Kentucky Planting Zones – USDA Map Of Kentucky Growing Zones
Information On Kentucky Climate Zones
This is the USDA Kentucky planting zone map. You can look at this map to learn the Kentucky climate zones and which one you live in.
In order to find your USDA planting zone, simply look at the map and locate where you live. Then, match the color of that location to the legend to the right. This will tell you which of the Kentucky climate zones you live in.
The Kentucky growing zone map above is based on the 2012 USDA map of growing zones. In 2012, the USDA map was revised to take into account the warmer temperatures that have been recorded in the past few decades.
Plants, particularly perennial plants, grow in specific temperature ranges. The USDA map simplifies the temperature ranges found in Kentucky and the rest of the US. Knowing your USDA Kentucky planting zone is important to your gardening efforts because it will help you choose plants that will thrive in the area that you live in.
You can find plants that grow in your planting zone at your local plant nursery or store. Reputable plant nurseries and stores will only carry perennial plants that have their proper growing zone clearly marked. The employees at your local plant nursery or store will also be able to help you choose plants that are appropriate for your USDA Kentucky planting zone.
Trees & Shrubs for Kentucky
Kentucky enjoys a moderate climate with warm, moist weather. Summers are warm and winters are relatively mild. The Bluegrass State’s weather is influenced by conditions in the Gulf of Mexico, especially during the summer months. The state’s annual rainfall is around 46-50 inches and spring is the rainiest season.
The Best Trees for Planting in Kentucky
Native Kentucky trees include Black Oak, Tulip Poplar, Sourwood, American Holly, American Beech, Red Maple, and Green Ash. With this in mind, we recommend that our Kentucky gardeners opt for native shrubs and trees that will adapt easily to their region and will thrive.
We Kentucky landscapers have full confidence in our range of fast-growing Tulip Poplar and American Beach, both of which provide dense shade trees to protect your garden and your home during the summer months. Our range of hardy Maples will also be right at home in your Bluegrass garden.
If you’re looking for privacy, consider planting a row of American Holly, Thuja Emerald Green, Cryptomeria Radicans or Drought Free Evergreens. These fast-growing evergreens will enhance the beauty of your property’s boundary while adding a sense of security.
A Large Variety of Trees for Kentucky
Wherever you live – the Bluegrass Region, the Cumberland Plateau, the Western Coal Field, the Pennyroyal Region, or the Jackson Purchase Region – we have the right geographical location. Our wide selection of trees for Kentucky is bound to provide long-lasting solutions for your landscaping needs. The Kentucky State Tree is the Coffee Tree.
The Kentucky soil series is Crider. This extensive soil makes up around 500,000 acres throughout Kentucky and is present in 35 counties. It is mostly used for cropping crops or for pasture. This is a highly productive soil and is ideal for growing trees and shrubs. If you have a different soil type on your property, it can easily be amended by adding organic matter and fertilizer.
Unforgettable Kentucky landscapes are usually a blend of different varieties of hardy shade trees, feathery evergreens as well as flowering shrubs and fruit trees. Choosing trees that are easy to establish in the KY soil conditions and climate will ensure that you have a landscape that is stunning and easy to maintain.
10 Common Plants To Avoid In Kentucky
Plant selection is never an easy choice. There’s the old adage of right plant, right place. But what criteria make a plant the right choice?
Often times plants are chosen based upon how pretty they are, which is why the same plants in flower sell faster than when they are out of flower. But the prettiness of a plant is not a good measure of its long term performance in the landscape.
The plant should also be the proper size for the location, adapted to the amount of sun exposure, tolerant of the soil conditions, and adapted to the climate conditions. Additional criteria to ensure the right plant choice is to consider pest and disease resistance.
Many of the most common landscape plants have serious problems, and they should be used with caution or avoided all together. Here is a list of 10 problematic trees and shrubs commonly found in Kentucky landscapes along with better alternatives.
- Trees to avoid:
- Ornamental Pear – These invasive trees are still available at many retail centers. Aside from the invasive problem, the flowers smell bad, the branches easily break in wind and ice storms, and they get fire blight.
- Alternative – Service Berry trees have attractive white blooms, edible fruit, and outstanding fall color.
- Ash – Once a common street tree in Lexington and Louisville, the Emerald Ash Borer (EAB) has devastated their populations both in cities and in forests. The presence of the EAB means Ash trees are no longer viable plants for our landscapes. Be wary of anyone still selling Ash trees in Kentucky.
- Alternative – Kentucky Yellowwood grows to a similar size as an Ash tree, but it has large panicles of fragrant white flowers in the spring (pictured on the right).
- Leyland Cypress – Fast growing and elegant, these evergreen trees simply are not hardy in Kentucky zone 6 winters. They may survive for a few years, but eventually they will get zapped by a true zone 6 winter and either die or look bad enough they’ll need to be removed.
- Alternative – Green Giant Arborvitae is a vigorous grower with a stronger upright habit and is perfectly winter hardy. Or use our beautiful native red cedars.
- Trees to use with caution:
- Purple Leafed Redbuds – The flowers of Redbuds are true harbingers of spring. There are many varieties of Redbuds, and the purple leafed varieties are very popular. Their purple leaves make a striking addition to any landscape, but these trees are highly susceptible to a type of fungal wilt that has no cure. It causes die-back in branches, attracts secondary infections, and will eventually kill the trees. Properly locating purple leafed Redbuds in well drained non-irrigated sites will help in managing the disease. Oftentimes, trees come infected directly from the nursery. Look for malformed leaves which can be an indicator of serious problems (pictured on the right).
- Alternative – The straight species green leafed Redbud, for whatever reason, is more resistant to the root rots than the purple leafed varieties. For a small tree with purple leaves, try the Purple Filbert which has the bonus of edible nuts.
- Crabapples – In springtime, Crabapples are glorious. Come summertime, they look ragged. Most Crabapples are attacked by a disease called apple scab which causes them to defoliate in the summer. Another disease, fire blight, also manifests during the heat of summer in the form of dead branches. Annual applications of fungicide can control apple scab, but fire blight has no cure.
- Alternative – Thankfully plant breeders have developed varieties of Crabapples that are resistant (not immune) to both apple scab and fire blight. Resistant varieties include Prairie Fire, Jewel Berry, and Dolgo among others. Do your research and make sure the Crabapple you purchase has resistance to both diseases.
- Pin Oaks – These majestic trees struggle in the Bluegrass. They often suffer from bacterial leaf scorch, which slowly kills them over a matter of years. Pin Oaks can survive if located in irrigated lawns or wet areas. Due to the prevalence of the bacterial leaf scorch which has no cure, Pin Oaks are best avoided.
- Alternative – Shumard Oak is a strong performer with excellent fall color.
- Shrubs to avoid:
- Dwarf Alberta Spruce – This cute evergreen is a mainstay of foundation plantings in many homes and businesses. Unfortunately, Dwarf Alberta Spruce is attacked by spider mites more so than any other plant. Spider mites are notoriously difficult to control and require multiple treatments annually. The shrubs never quite recover and can also act as an infection point for the rest of the landscape.
- Alternative – The Dwarf Hinoki Cypress is an elegant slow growing plant.
- Inkberry Hollies – This would be the perfect native shrub, except that it is highly prone to root rot. Most every Inkberry Holly in Kentucky shows signs of infection, and they die a quick death. Late stages of decline show as large dead areas in the shrub (shown on the right). Fungicides do not always work as some of the root rots have no cure.
- Alternative – Use another native holly, Winterberry Holly. It may not be evergreen, but it provides an awesome show of color all winter long.
- Shrubs to use with caution:
- Knockout Roses – For decades, no flowering shrub has been more popular. But a recent virus, called Rose Rosette Disease, is spreading quickly. It deforms the plants and flowers eventually leading to death. If a plant is found with this virus, it is best to remove and destroy the plant before the infection spreads.
- Alternative – It is difficult to find a perfect replacement for Knockout Roses, but several Hydrangeas come close. The Oakleaf Hydrangea “Ruby Slippers” or Panicle Hydrangea “Fire Light” are among several varieties with large blooms that fade to deep red.
- Azaleas – A true classic landscape plant. Unfortunately, Azaleas struggle in the Bluegrass. Our soils are not acidic enough for them to thrive, they suffer in our heavy clay soils with root rots, and the leaves are attacked by lacebugs. Azaleas can be grown successfully, but they require a lot of work, site prep, and diligence.
- Alternative – Another native spring bloomer, Fothergilla (pictured to the right) has fragrant white bottlebrush flowers and lovely fall color. Several varieties are available with blue foliage as well.
Fall is for planting. It is probably one of the most popular slogans of the garden center world, and it is true.
Peak fall planting season in our area runs from mid-September until mid-December. This is the most successful time of year for planting trees and shrubs because the environment is the most conducive for establishment and growth of the root system.
The root system is considered the most important part of the plant. Without a healthy, vigorous root system, trees and shrubs are fighting an uphill battle for survival. I am often called to evaluate trees and shrubs that are not doing well. What I have observed is that if the root system is severely damaged or diseased, this type of injury is very difficult, if not impossible, to correct or repair.
Of course, the actual variety of tree or shrub is very important too, but so are a host of other factors. I am constantly recommending varieties for specific characteristics, both visual and internal. But without proper care in the nursery, protected transportation home, correct planting techniques, excellent maintenance after planting, and proper site selection, all the research in the world—finding the No. 1-rated tree on the market and paying top dollar—won’t help it survive.
The big oaks
If you are planning on planting any large shade trees this fall, there are a few I highly recommend. The first is actually a group of plants, the oaks. Within that group, there are a few we do not recommend planting, but the oaks we definitely like are bur oak, Quercus macrocarpa; willow oak, Quercus phellos; and swamp white oak, Quercus bicolor.
These three varieties of oak can grow more than 100 feet tall, although in most urban landscape environments they do not reach quite that tall. All make beautiful shade trees, and while their growth rate is only medium to slow, it is worth the wait. The oaks are typically a very forgiving group, growing successfully in situations that are not always perfect.
Colorful sugar maple
Another beautiful shade tree that often goes overlooked is the sugar maple, Acer saccharum (not to be confused with the awful silver maple, Acer saccharinum). Sugar maple is known for its amazing and consistent fall color and matures to a height of typically just under 100 feet, again slightly shorter in most urban environments. It is considered to have a faster growth habit than the oaks, making it a more popular choice where a shade tree is needed. Sugar maples are harder to find, but worth the effort.
Popular native black gum
Rounding out my top three is my personal favorite, the native black gum, Nyssa sylvatica.
The black gum (not to be confused with sweet gum, Liquidambar styraciflua) is an amazingly beautiful shade tree. In the summer the foliage is a glossy dark green, turning the most stunning scarlet red in autumn. It is the smallest of the group, growing only 50 to 75 feet tall, considered a medium-rate grower, and today is more commonly planted than the sugar maple or the oaks.
Big trees require big spaces, so plant appropriately. If the available area in your front or back yard is 30 feet wide or less, you may not have enough room for one of these big shade trees and should consider selecting something slightly smaller.
Know your space, do your research, and take special steps to ensure the establishment, optimal health, and survivability of our trees and shrubs. I hope you will celebrate this beautiful fall season and plant a tree for future generations in your garden, perhaps planting one for a friend or one in memory of a family member.
ASK THE GARDENER
by Angie McManus
When should I cut back my peonies? Some of the leaves have dark brown spots on them.
Peonies can look a bit ragged this time of year, but it really is best to leave the foliage until after the first frost arrives. The plant is now storing up food and nutrients essential for next year’s growth and blooms. The longer the foliage has to photosynthesize, the healthier the peony will be. As far as the brown spots on your plant, you should find out what you are dealing with just so you know. When peonies are not planted in ideal situations or if they have poor air circulation, they are more susceptible to fungal problems, including botrytis and other blights. A rainy season can increase fungal problems. If this is the case, you should remove all infected foliage. It should not go into your compost pile but rather with the yard waste. Your county Cooperative Extension Service is a reliable place to take a sample of your peony. The horticulture agent will be helpful in diagnosing the problem and giving you options for treatment and prevention.

Flag of Kentucky.
What time is it in Kentucky? This is a commonly asked question — but this question requires a question in return — where in Kentucky?
Kentucky actually has 2 time zones — the Central and Eastern Time Zones to be exact. Approximately 60% of Kentucky is located in the Eastern Time Zone with the remaining 40% of Kentucky in the Central Time Zone.
As a general rule, the western part of Kentucky (left side) is located in the Central Time zone while eastern part of Kentucky (right side) is located in the Eastern Time zone. But there are exceptions to the rule.

What Time Is It In Kentucky? There Are 2 Time Zones
The time in Kentucky can actually be a little bit confusing.
Any Kentucky County that is 100% east of 86°30’W is in the Eastern Time Zone — but there are 11 counties to which this rule does not apply.
The 11 counties that are the exception to the rule are: Adair, Allen, Barren,Clinton, Cumberland, Edmonson, Hart, Green, Metcalfe, Monroe and Russell.
All other Kentucky Counties plus the 11 counties mentioned are in the Central Time Zone.
