Create a Winter Container Garden
The holidays are literally right around the corner! Have you gotten all your decorating done? You may have answered yes to that question, but have you thought about the outdoor decorations? Have you ever heard of a winter container garden? Yes! You can create a container garden in the winter time. To find out just how to create a winter container garden, stay with me on the Sunshine Gardening Podcast for my secrets on creating a gorgeous winter container garden for this holiday season!
Remember that pretty container filled with annual flowers that was used all summer and maybe even to fall if you weren’t too tired? Well, the same container can be re-worked and situated in your home’s entryway to welcome close family and friends in for the holidays!
To begin creating a winter container garden, use a hard plastic or wood container that can withstand the harsh winter elements filled with potting soil mix. Make sure the potting soil is a little below the top rim of the container. If not, add more potting soil or use newspaper to bring it closer to the top.
Next, collect clippings from different landscape trees and shrubs growing around your home or neighborhood. Examples of greenery might include southern magnolia, white pine, Eastern red cedar, holly, heavenly bamboo, spruce, boxwood, and Eastern hemlock. Cut varying lengths of greenery when gathering samples. The thought is to use the longer pieces to “spill” out of the arrangement and the shorter pieces to “fill” in around the spiller plants.
Kentucky’s landscape is filled with different varieties of evergreen trees and shrubs that can be cut and used as fresh greenery in a number of holiday decorations for the home! Take a look around your yard to see what greens are available in your neighborhood.
- White Pine, scientifically known as Pinus strobus, offers a blue green color to arrangements and provides a nice fragrance when situated in the home. Not to mention, it has excellent needle retention.
- Another readily available greenery item is Eastern Redcedar, Juniperus virginiana, which possesses fleshy blue berries for good color and smells wonderful when brought indoors.
- Southern Magnolia, Magnolia grandiflora, a favorite among Southerners has glossy, dark green leaves with velvety, brown undersides that give an interesting contrast when placed against other leaf textures.
- Holly is another traditional holiday green that adds interest depending on the variety that is being used. Some leaves give a blue color while other holly varieties can be variegated. If looking for berries, make sure to collect from the female plant.
- Eastern Hemlock, Tsuga Canadensis, is one of my favorites to use around the holidays for decorating. This evergreen gives a lacey effect to fresh arrangements. The leaves are flat and the undersides have more of a white appearance on the undersides. At the ends, find small pinecones that look like little ornaments attached.
- Other types of greenery such as Colorado Blue Spruce, and Boxwood are acceptable, too.
Things to know before cutting. Make sure to use clean, sharp cutters and cut at an angle for better transport of water and nutrients. Before cutting greenery from trees in the landscape, carefully consider which branches need to be cut. It is best to distribute cuts evenly throughout the tree or shrub to preserve its natural form.
The tips to know to ensure freshness! After cutting the greenery, immerse stems into a bucket filled with water and soak it overnight to maximize moisture. An optional step would be to allow the greenery to dry and then spray it with an anti-transpirant such as Wilt-pruf to help seal in additional moisture. However if you are using blue spruce, juniper berries, or cedar avoid using anti-transpirants, since this product can damage the wax coating that gives the plants their unique color.
Now comes for the fun part—creating the winter container garden! Here are some items that you will need before you begin the process.
Gather up a round tomato cage and turn it upside down where the wire stakes are pointed up. The round part of the tomato cage should be positioned on the bottom with the 4 prongs facing upward to look similar to a Christmas tree. This piece will serve as the thriller in this arrangement and also give the container some height.
For some added cheer, attach Christmas lights to the tomato cage using floral wire. Use a spiral pattern when adding the lights to the tomato cage, or if you prefer more lights, place strands on each wire of the tomato cage. Don’t forget to place the plug-in towards the back of the container and next to a plug-in.
After getting the lights attached, put a block of green floral foam in a sink filled with room temperature water. The floral foam will support the greenery in place and keep it fresh by holding in moisture. Avoid forcing it down in the water where air bubbles form and allow the water to slowly soak into the block like a sponge and sink to the bottom. Floral foam can be purchased at most big box stores or at your favorite craft and floral supply store.
Place the block of wet floral foam in the middle of the container, and put the round base of the tomato cage over the foam. Next, take a roll of clear tape and secure the sides of the cage and floral foam to the container to keep it from falling over.
Cut stems of greenery at an angle and insert them into the wet floral foam. Start on the sides, then the front, and back of the arrangement, so the greenery appears as if it is cascading over the sides of the container. Add smaller pieces of greenery to fill in around the spiller until the foam is no longer visible.
After the greens are placed, for the finishing touch, incorporate natural elements like red berries, magnolia pods, or pine cones for a creative personal touch. Place your arrangement near the entrance of your home and watch how it glows with glamour from top to bottom! Guests will enjoy viewing these fresh arrangements around the holidays, and you will appreciate it more, knowing that you created it yourself using natural materials from around Kentucky’s landscape!

Don’t forget that the pumpkin seeds can even be eaten too! Take the seeds and roast them in the oven. Add your favorite seasonings and you have a healthy snack or seasonal salad topper.
#2. Decorate Them!
One fall activity that youth look forward to is pumpkin decorating! Take your family to a local pumpkin patch to pick out their own pumpkin. Once you have picked out a pumpkin then your child can select their preferred method on how to decorate their pumpkin, without the hassle of having to carve them too! Options may include painting their pumpkins with acrylic paints or creating their own designs. Parents may want to purchase decorating kits at local crafts stores. The kits can be purchased in all different designs like dinosaurs, cats, Disney characters, or funny jack-o-lantern faces. The best part about these kits is they can be recycled year after year. Another option is fun 3-D stickers where kids can make funny faces on their pumpkin. The last kit used was a cat kit that came with foam parts and pipe cleaners. With the foam Halloween decorating kits, it contains everything that a parent would need to help their child decorate their pumpkin. If you do plan on carving the pumpkin, carving design books are available where the design is perforated instead of having to use scissors to cut them out.
#3. Create a Fresh Pumpkin Centerpiece using Natural Elements!
With pumpkins in a huge supply this October, create a fresh do-it-yourself pumpkin centerpiece to brighten up your lovely abode! First, gather a few materials to begin your project — a sharp knife, a big spoon, one block of wet floral foam, clear tape, scissors, a small pie pumpkin, and a variety of seasonal flowers and natural elements from the landscape such as garden canna, dried hydrangeas, purple basil, sedum, and goldenrod.
Begin by soaking a block of floral foam in a sink filled with cold water to get it wet. Allow the water to gradually soak up into the foam and avoid pushing it down in the water where it can gather air bubbles. While the block is soaking, take the pie pumpkin and with a knife carve a circle around the top of the pumpkin’s stem to hold the wet foam of your arrangement. Remove and discard the seeds and pulp.
Next, place the water saturated block of floral foam inside the pumpkin. You may have to cut it with a knife to make sure that it fits in the opening of the pumpkin. This is the perfect membrane for holding the mechanics of the arrangement.
Add the thriller of the arrangement first which would be the tall garden canna to give it some height. Make sure to cut stems at a diagonal so water will easily transport up the stem. Next, add dried hydrangeas to serve as the main flower for the arrangement. Place the purple basil greenery around the hydrangeas to give a nice pop of color. Lastly, add the stems of sedum and goldenrod as the filler flower to fill in the dead space and finish the arrangement.
#4. Make a Gratitude Pumpkin!
Spend time with family by creating a gratitude or a thankful pumpkin. To create this pumpkin, take a black permanent marker and have each member of the family write what they are thankful for each day. Keep the pumpkin on the table until Thanksgiving to serve as a reminder of what your family is thankful for this season!
#5. Assemble a Table Centerpiece using Pumpkins!
Another way to use other pumpkins this season is to create a pumpkin centerpiece! Grab a white plate or tray from around the house, other types of pumpkin whether it be multi-colored ones or small white ones, and collect fall clippings from trees and shrubs around the landscape to create a simple fall centerpiece for the table!
To begin this process, place one type of tree cutting on the bottom of the white plate or tray to serve as the base. In the picture above, we used a deciduous shrub showing bright red berries. In the picture below, we selected heavenly bamboo. Next, place the pumpkins on top of the leaf clippings. Make sure to use an odd number of pumpkins like 3’s or 5’s. Next, add another type of colorful fall foliage around the pumpkins for some accent color like the red maple or even the Northern Sea Oats. For some extra embellishment, place small raffia bows around the stems of the pumpkins. You can also add little tea lights around the pumpkins if you have any extra room. Another added touch would be to personalize the pumpkins with Thanksgiving sayings or blessings for the table. Have fun and be creative!
#6. Make a Pumpkin Bird Feeder!
This is a fun project and activity to perform at home and involve the kids. Plus it helps to feed the birds at the same time!
To make the pumpkin bird feeder, use a small to medium sized pumpkin and with a knife cut and remove all the guts of the pumpkin. To make the hanger for the pumpkin bird feeder, take heavy-duty string and attach it to the sides of the pumpkin by drilling a hole. Another option is to place the string around the sides of the pumpkin and in the grooves and secure it down with clear tape. Tie the string together in a knot if using several pieces of string. Place birdseed in the center of the pumpkin, based on the birds you wish to attract. If you want to provide a place for the birds to perch when feeding, add tree branches or small twigs to the sides. Hang up the finished pumpkin bird feeder in a tree and watch the feathery friends from your favorite window.
#7 Lastly, recycle the pumpkin to the compost pile!
It is always good to return nutrients to the soil by composting it. Cut up the pumpkin(s) into sections or quarters and add it to the compost pile. Add water and turn it often with a garden fork to incorporate with other materials from the compost pile. In a few short months, the compost pile will reduce in size and finished compost will smell earthy, feel crumbly, and appear dark in color.
Fall Home Lawn Improvement Practices
Do you have trouble establishing a good stand of grass in your home lawn? Do you notice bare spots? Do you have more weeds than grass? If you answered yes to any of these questions, fall is the absolute time to carry out several home lawn improvement practices to help improve the appearance of your Kentucky home lawn. Today on episode 11 of the Sunshine Gardening Podcast, I am sharing the top 4 secrets to improving your home lawn this fall. For all the details, stay right here on the Sunshine Gardening Podcast!
#1. When is the best time to perform lawn care practices in Kentucky? The turf care calendar for cool season lawns in Kentucky is found at the beginning of this guide. It shows each month of the year and highlights the best and second best times to perform specific lawn care practices for the Kentucky lawn. There are also foot notes located at the bottom of the page that gives more explanations related to the specific lawn care practices.
#2. Select the right grass for the Kentucky lawn. Based on research from the University of Kentucky, turf-type tall fescue performs the best for Kentucky Home Lawns. Tall fescue has good qualities including: There are also some slight drawbacks which include good traffic tolerance. For a link to see the publication on Selecting the Right Grass for your Kentucky Lawn, make sure to see the show notes. This publication explores the different types of grass species that can be grown in Kentucky and lists major qualities and problems associated with each grass type. Recommendations for the top performing varieties of tall fescue and other cool-season grasses are also included in this guide.
#3. Soil Test, Soil Test, Soil Test! The secret to having a nice looking lawn is by conducting a soil test. I often say that the secret to good plant growth is through the soil and by testing the soil, this process gives homeowners the exact recommendations of lime and fertilizer rates needed to reach optimum plant growth. To improve the appearance of the lawn, first start with a soil test.
To test the soil for a home lawn, sample the top 2 to 4 inches of soil using a garden shovel or trowel. Collect soil from different locations in the lawn at random and make sure to avoid getting any grass clippings or leaves when sampling. Some people sample their front and back yards separately. Place soil in a clean five-gallon bucket. Repeat this same process 10 to 12 times and mix all the samples together. If there is any excess moisture in the soil, allow the sample to dry on newspaper for 24 hours.
After collecting soil, bring samples to the local extension office. Some basic information about the crop being grown is needed to go along with the sample before being mailed. There is a small fee to pay for conducting a soil test, but I assure you that it is the best money that you will spend since it gives you the exact amounts for lime and fertilizer that is needed. When results come back, extension agents review and sign the soil test recommendations. Soil test results generally take about 7 to 10 days to be processed.
#4. When should I fertilize my home lawn? Fertilization is an important part of maintaining a home lawn. Fall is the absolute best time to fertilize cool season grasses in the Kentucky home lawn. By performing this practice in the fall, the root system is stronger and can make it through the winter months. September, October, and November are the best months to apply fertilizer according to soil test recommendations.
The number of times nitrogen fertilizer is applied depends on the lawn quality desired. Most general home lawns with no irrigation system are maintained at the low to medium maintenance levels. These levels require either one or two applications of nitrogen. Make sure to have the soil tested to know these exact recommendations for the home lawn.
If interested in knowing more information about home lawn fertilization, make sure to see the link in the show notes to achieve the publication for Fertilizing your Lawn, AGR-212.
While I know that I gave the top 4 secrets to improving your home lawn this fall, I also have a free resource that I am offering up today that can offer more help in home lawn improvement practices! This free resource is called the Home Lawn Improvement Guidebook. This guidebook will assist you in making the best decisions for how and when to improve the appearance of your Kentucky lawn. Material in this guidebook is provided by University of Kentucky Cooperative Extension Turf Specialists and other Extension Professionals. If you would like a copy of this guidebook, make sure to contact the Warren County Extension Service at (270) 842-1681 or contact Kristin Hildabrand at kristin.goodin@uky.edu.

Cover Crops for the Kentucky Garden
Photo Source: Rachel Rudolph, UK Extension Vegetable Specialist
Our gardens are finally slowing down for the season. One thing you may ask yourself is should I consider sowing a cover crop for my Kentucky garden? Your mind may wonder next what type of cover crop should I sow? How is the best way to sow a cover crop? To find out more information about cover crops, I contacted our UK Extension Vegetable Specialist Dr. Rachel Rudolph to see what recommendation she had on cultivating cover crops. After talking with her, I discovered selecting a cover crop comes down to what you are hoping to accomplish for your garden plot.
University of Kentucky Extension Vegetable Specialist
Why would gardeners want to sow cover crops for their gardens? What are the advantages or benefits? Cover crops have the potential to lend several benefits for the Kentucky garden. Most of the benefits proven through research are increased soil organic matter, weed suppression, soil structure improvement, pest and pathogen suppression, soil micro-organism promotion, improved nutrient cycling and management, increased water infiltration, reduced soil erosion, and even attract and provide habitat for native pollinators to the garden.
Which cover crops perform best for Kentucky gardens? Generally not one cover crop will capture all the benefits listed above. The question goes back to the home gardener to decide “why do I want a cover crop?” and “what am I hoping to accomplish in my garden?”. Once you answer that question, it gets much easier to implement a cover crop for the garden. For example, let’s say that you desire a cover crop for weed suppression. The next question you may ask is what time of year do I want to deal with weed suppression? You may answer this question as the winter and summer months are needed more for weed suppression. Make sure to know what growing location you are located in as well as the soil type. Also, consider what type of crops are being grown in your garden. What will happen after these crops come out of the garden? What does your timeline look like? Once you answer some of those basic questions, you will better understand what cover crop is needed or wanted for your garden.
If you are looking for a cover crop that might check multiple boxes for benefits with the home gardener, cereal rye might be a good option! With cereal rye, it will increase organic matter content in the soil, reduce weeds, improve soil structure, promote soil micro-organisms, decrease soil erosion, increase water infiltration, and help improve nutrient cycling.
@ The UK Horticulture Research Farm
How should we prepare before sowing cover crops in the garden? Before getting started, home gardeners should do their homework to know how much biomass will be produced from their specific cover crop being grown. For instance, cereal rye can get several feet tall at maturity, so ask yourself, are you equipped to handle it. Make sure that you are prepared and ready for when that times comes. Also, understand when the cover crop needs to be terminated.
When it comes to seeding these cover crops, most of them can be sown by broadcast seeding it. To know how much to apply over the area, measure the acreage of the garden and know what the recommended seeding rate for the cover crop. Next, prepare to broadcast the cover crop seed over the area. It may be helpful to mix it other additions such as potting soil or sand, so you feel it better and achieve better coverage when broadcasting the seed over the ground.
Next, prepare the soil before sowing the cover crop. Soil should be loose, crumbly, and soft on the top like planting for a vegetable garden. Gardeners should be able to rake the soil softly over the entire area. Avoid rocky or compacted soils.
If someone would like to learn more about cover crops, here are some other good resources to consider adding to your library.

Have you noticed Hammerhead Worms?
Last week, a client sent me a photo of a hammerhead worm. To be honest, I had never seen one or even heard of it before. I thought this article would shed more light on this unique creature. Read here to find out more information about hammerhead worms.
Hammerhead worms are flattened, very long earthworms, and have a broad shovel-like head. They can be 10 or more inches in length. Please see the picture below received from a Warren County resident.
Hammerhead worms are earthworm and mollusk predators and have been a problem in earthworm farms. These are terrestrial planarians. They are able to detect secretions left by earthworms in the soil, and then track, kill, and consume those earthworms. They are able to kill earthworms many times their size as hammerhead worms can use a neurotoxin (tetrodotoxin) to paralyze the worm. Hammerhead worms have the potential to greatly impact local earthworm populations. These hammerhead worms have few predators.
Reproduction can be sexual, or asexual as all the species are hermaphroditic. Some species can use fragmentation, fission of posterior body fragments. These diverse reproductive strategies enable hammerhead worms to spread rapidly.
While there are native hammerhead worm species, this species appears to be invasive from southeastern Asia; however, I am not able to confirm this. This species is widely distributed and has been in the United States for over a century.
Information for this article was taken from Ric Bessin, Entomology Extension Specialist Kentucky Pest News article published on September 8, 2020 found at https://kentuckypestnews.wordpress.com/2020/09/08/hammerhead-worms/.
Summer Garden Pests
Home gardeners are busy harvesting their crops until the summer garden pests move in! To talk to an expert, I called up UK Extension Entomologist Dr. Jonathan Larson to see what information he could provide to keep these summer pests under control.
A popular summer pest in the Kentucky garden is the Japanese beetle. Japanese beetles are easily recognized by their attractive, shiny emerald-green and copper color. They are about 7/16 of an inch long, and if you look closely, you’ll see patches of white hair on their sides.
The beetles have sharp, chewing mouth parts that allow them to grind up tender leaf tissue between the veins, leaving the leaves skeletonized and lacy. But they don’t stop at leaves. They will shred flowers – you’ve probably seen them buried into the blooms on your roses – and even eat fruit. They attack and feed on more than 300 different plant species. Their favorites include linden, roses, grapes, blackberries and peaches.
So how do you protect your garden from Japanese beetles? First, if you’re in the process of planning or planting your landscape, consider including species and cultivars they don’t like to eat. Examples of those are most oaks, hollies, tulip trees and silver maples.
For those of us whose landscapes are mature and planting more trees isn’t feasible, one of the best methods is to simply pick off and kill beetles when you see them on your plants. Beetles will be strongly attracted to a plant that is already damaged by beetles. The more damage, the more beetles, resulting in more damage and more beetles. It’s a vicious cycle. If you walk through your garden in the evening and remove beetles by hand, you’ll cut back on the number of beetles that show up the next day. Pick them off and plop them in a bucket of soapy water.
There are insecticides available that can help kill or repel beetles, but always follow the label instructions carefully and beware of treating any plant that is blooming. Organic options, which offer a three to four days of protection, include Neem oil, pyola and BtG (Bt for beetles). Synthetic options, which offer protection for one to three weeks, include bifenthryn, carbaryl, cyfluthrin and lamda-cyhalothrin.
Another common summer garden pest is the squash vine borer. The squash vine borer is a key pest of squash, gourds, and pumpkins in Kentucky. Symptoms appear in mid-summer when a long runner or an entire plant wilts suddenly. Infested vines usually die beyond the point of attack. Sawdust-like frass near the base of the plant is the best evidence of squash vine borer activity. Careful examination will uncover yellow-brown excrement pushed out through holes in the side of the stem at the point of wilting. If the stem is split open, one to several borers are usually present. The caterpillars reach a length of 1 inch and has a brown head and a cream-colored body.
Monitor plants weekly from mid-June through August for initial signs of the borer’s frass at entrance holes in the stems. Very early signs of larval feeding indicate that other eggs will be hatching soon.
Home gardeners may have some success with deworming the vines. At the first signs of the sawdust-like frass, vines are slit lengthwise near where the damage is found and the borers removed. The stems should be immediately covered with earth. Sanitation is also important. After harvest is complete, vines should be removed from the garden and composted to prevent the remaining borers from completing larval development.
Gardeners should also be concerned with ticks that can harm the body. To hear the full interview with Dr. Larson, make sure to check out Episode 9 on Summer Garden Pests from the Sunshine Gardening Podcast!
We appreciate Dr. Jonathan Larson being our guest on the show! If you would like to learn more about insects, Dr. Larson also has his very own podcast called Arthro-Pod. To hear more about what is covered on the Arthro-Pod, click here: http://arthro-pod.blogspot.com/.

Creating a Hydrangea Heaven
June is the month with blessings from several varieties of the Hydrangea shrub in the Kentucky garden and landscape! Hydrangeas are the number 2 most popular shrub planted in the home landscape. It grows in zones 3-9 and offers different shapes and colors of blooms for the landscape throughout the growing season. This plant is relatively pest free if planted in the correct place for bloom production.
Uses of Hydrangeas
Hydrangeas can be used in mass planting, border, and as an accent or specimen plant.
Types of Hydrangeas:
Smooth Hydrangea- Hydrangea arborescens
Oakleaf Hydrangea- Hydrangea quercifolia
Panicle Hydrangea- Hydrangea paniculata
Bigleaf Hydrangea- Hydrangea macrophylla
Watering
Hydrangea means “water lover” in Greek where “hydra” means water and “angeon” means “vessel”. After planting, water hydrangeas consistently throughout their first year. Even after establishment, hydrangeas will require 1 inch of water per week either by rainfall or irrigation. Additional water may be needed in a sunny or windy location. Make sure to give hydrangeas the proper location based on the type being grown and provide ample amounts of mulch to conserve soil moisture and keep roots cool.
How to Adjust Bigleaf Hydrangea Flower Color
For Bigleaf hydrangea also known as Hydrangea macrophylla, blooms can vary by color from true blue, deep purple, to pink according to the soil’s pH or the availability of aluminum in the soil. For example, in acid soils, aluminum is more available and leads to a blue bloom color. In basic or more alkaline soils, aluminum is found in less amounts and gives a pink bloom color.
Altering soil pH for hydrangea production can take up to 6 months and requires a basic soil test for complete accuracy. Based on soil test recommendations, add powdered or pelletized lime or sulfur in the fall for desired pink or blue blooms for the following summer.
Remontant Hydrangeas
Remontant hydrangeas also referred to as “repeat bloomers” are plants that flower more than once in a single growing season. Some top mophead remontant selections include ‘Blushing Bride’, Endless Summer ‘Bailmer’, ‘Decatur Blue’, and ‘Nantucket Blue’. “Twist-n-Shout’ is the only remontant lacecap type. The bigleaf hydrangea cultivars are more strongly remontant. Make sure to fertilize remontant hydrangeas to help support repeat blooming.
Pruning
In order to prune hydrangea, know the type you have and understand if it blooms on old or new wood.
“Old Wood” refers to previous year’s growth. Hydrangea cultivars with old wood formed the buds the year before.
“New Wood” refers to the current year’s growth. Hydrangea cultivars that bloom on new wood set their buds during the year in which they bloom.
When is the correct time to prune specific hydrangeas?
Smooth hydrangea blooms on the current year’s growth. For this type, prune back by early March, so plants have time to grow stems and form flower buds.
Oakleaf hydrangea– allow this type to grow in its natural form and prune as little as possible. Oakleaf hydrangea flowers are produced on old wood. If pruning is necessary, finish by the end of July to ensure that there is still time for next year’s flower buds to develop.
For panicle hydrangea, pruning isn’t needed. If you would like to create a neater and tidy appearance and help increase the size and number of blooms, cut the plants back hard to approximately two buds. The blooms will develop on new stems, so make sure that this pruning is performed once plants go dormant through early March. If you desire, panicle type hydrangeas can be trained to a tree form unlike other hydrangeas. Begin training at an early age and requires a stake to help support. To keep the tree form shape, remove branches that develop from the trunk several times throughout the year.
Once bigleaf hydrangea is mature, prune no more than one-third of the older branches to the base of the plant in early spring. Pruning will rejuvenate the plant without a large loss of flowers. To reduce size or for shaping, prune after blooms fade but no later than the end of July.
