Real gardening tips for Kentucky’s clay soil, unpredictable weather, and humid summers—from an Adair County gardener figuring it out alongside you.
Welcome to Bloom & Peck’s Kentucky Zone 6 & 7 Gardening Hub—where I share what’s actually happening in my Zone 7a garden, wins and fails included.
Are you new to Bloom and Peck? Want to know more about why I homestead in Kentucky, you can see that here.
I’m not a master gardener or an expert. I’m learning as I go, dealing with the same Kentucky clay soil, surprise spring frosts, and July heat waves that you are. Some things work great. Some things… well, let’s just say the chickens enjoyed those failed lettuce starts.
This garden hub is where I’m organizing everything I’m learning about gardening in Kentucky Zones 6b, 7a, and 7b—the stuff that’s working, the experiments in progress, and the honest mistakes so you can skip them
New Kentucky Planting Calendar
Just updated a new 3 zone Kentucky Vegetable Planting Calendar, and it is free to check out and a printable via email! See the article HERE
🌍 What Zone Am I In Kentucky?
Kentucky spans USDA Zones 6b, 7a, and 7b depending on where you live:
☁️ Zone 6b (Northern Kentucky, higher elevations)
- Last frost: Late April/early May
- First frost: Mid-October
- Coldest winters
☁️ Zone 7a (Louisville, Lexington, central KY)
- Last frost: Mid-April
- First frost: Late October
- Most common zone in Kentucky
☁️ Zone 7b (Southern Kentucky)
- Last frost: Early-mid April
- First frost: Late October/early November
- Warmest zone
Good news: Most of what works in one zone works in the others—you just adjust your planting dates by 1-2 weeks. I’ll note when zone differences really matter!
When in doubt of what zone you are in You can look it up by your zip code, Here is a link that will help you from Farmer’s Almanac–
🌱 WHAT I’M LEARNING ABOUT KENTUCKY GARDENING
Understanding Kentucky’s Zone 6b/7a Climate (The Real Version)
What “Zone 6b/7a” actually means for your garden:
- Last frost is supposed to be mid-April (but I’ve seen May frosts, so… 🤷♀️)
- First frost hits around mid-October (earlier if you’re in a valley)
- Growing season: About 200 days (when Mother Nature cooperates)
- Summer = hot, humid, and rain when you don’t want it (or drought when you do)
- Clay soil = nutrient-rich but DENSE (amending is a must)
What I’ve learned the hard way:
- Don’t rush tomatoes out in April with out protection (even if it’s 75°F that day)
- July and August require shade cloth (trust me on this)
- September is actually the best planting month
- That “last frost date” is more of a suggestion than a rule
- No matter What the weather looks like in February, wait for it….
update – I got to excited and did not cover my pea seedlings and we had a March freeze after a week of 70 degrees. Don’t be like me, take precautioins
This is where I talk about growing peas in Kentucky..

🍅 GROWING FOOD IN KENTUCKY (My Ongoing Experiments)
Tomatoes (My Main Obsession)
I’m slightly obsessed with getting tomatoes to thrive in Kentucky’s heat and humidity. Here’s what I’m learning:
What’s working:
- Best Tomatoes to Grow in Kentucky: Zone 6 & 7 Guide
The varieties that actually survive our summers (not all heirlooms make it) - Tomato Trials Series
My ongoing experiments with trellising, companion planting, and keeping hornworms at bay
What I’m still figuring out:
- The perfect spacing for airflow (humidity is REAL)
- When to give up on a plant vs. when to keep trying
- Whether determinate or indeterminate works better here
Update 3/19/2026- I am growing Kentucky Beefsteak, San Marzano, German Pink, and Sun Gold tomatoes this year! Will report back on those soon!
Potted up the tomatoes they are looking good! 3/27/2026 update.
Other Veggies I’m Growing
Sweet Potatoes:
- Starting Sweet Potato Slips in Kentucky
My trial-and-error journey with slips (spoiler: clamshell containers work!)
Cucumbers:
- Learning about trellising (my arched trellis is working great!)
- Dealing with powdery mildew (ongoing battle)
Peppers:
- They LOVE Kentucky’s heat (one success story!)
- Still learning optimal planting times
Coming soon as I try them:
- Thelma Sanders Squash
- More companion plant
- Garlic, planted in november I will share my success and failures
Update Garilc pit fall check it out - Onions – plants, Just got my Dixondale order in! March 27th, 2026

- Cabbage
- and more! I will share as I “Grow”
🌼 COMPANION PLANTING (My Favorite Experiment)
I’m all-in on companion planting because it’s like a puzzle I get to solve:
What I’m testing:
- Companion Planting for Kentucky Gardens
What grows well together here (spoiler: marigolds are my best friend) - Companion Planting Series
My ongoing tests—some wins, some “well, that didn’t work”
Current experiments:
- Pollinator rings around my raspberry bushes
- Three Sisters method in Kentucky clay (we’ll see…)
- Herbs that help (and which ones the chickens destroy)
📅 WHAT TO PLANT WHEN (As I Figure It Out)
I’m building this section as we move through the seasons! Check back for updates.
Spring in Kentucky
March:
- Cool-season starts (peas, lettuce, spinach)
Peas are getting a raised bed and arched trellis to be followed by cucumbers.
March 2026- Peas are out, I transplanted Garlic (hope it does well), Potting up tomatoes, broccoli, cabbage and peppers. - Seed starting indoors (tomatoes, peppers) update March 22nd, (Ok I did this early in 2026 Ooops-but glad I did my Jalepenos did not germinate)
- Hoping the chickens don’t scratch up the new beds
- Transplanting strawberries end of month ( I did not get this done ini Marach 2026)
- Transplanted Raspberries
April:
- Still frost risk—learned this the hard way
- Planting potatoes (fingerling experiment happening!) (2026 Mine were growing crazy in the basement in March so I planted them!)
- Getting tomato bed (never too early)
- Plant Onion Plants and Broccoli, other cole crops.
May:
- FINALLY safe for tomatoes (usually after May 10th)
- Warm-season planting begins
- Companion planting setup
Summer in Kentucky
June:
- Everything is growing! (Or dying from heat… one or the other)
- Companion planting starting to show results
- First harvest excitement
July:
- Shade cloth is a MUST
- Keeping plants watered (but not drowned)
- Fighting humidity and pests
- Questioning my life choices (kidding… mostly)
August:
- Some plants are thriving, some are done

- Collecting seeds (when I remember)
Fall in Kentucky
September:
- I love the Fall Succession Planting

Winter Projects
Planning next year (and forgetting half my notes)
Winter Sowing Without Milk Jugs
Using clamshell containers (works great!)
🛠️ MY KENTUCKY GARDEN SETUP (Budget Edition)
Dealing with Clay Soil (The Struggle is Real)
What I’m learning:
- Clay isn’t BAD, just… challenging
- Amendments are your friend (compost, peat moss, perlite)
- Raised beds help A LOT
- No-till is tempting but I’m not there yet
Coming soon as I test more:
- What soil amendments work best
- Building soil over time
- When to just embrace the clay
My Garden Beds & Containers
What I’m using:
- 7 Best Metal Raised Garden Beds for Kentucky
The ones that survive our weather (I tested them so you don’t have to!) - Salt lick tubs (free from a local farm, work great!)
- Thrifted containers (whatever I can find)
- In-ground beds (with LOTS of amendments)
DIY Projects I’m working on:
- Cattle panel trellises (surprisingly affordable!)
- Shade cloth setup (trial and error happening)
- Compost system (currently a messy pile, working on it)
🐛 KENTUCKY GARDENING CHALLENGES (What I’m Dealing With)
Pests I’m Fighting
Tomato hornworms:
- Hand-picking is my go-to (gross but effective)
- Considering Bt spray from Epic Gardening
- Chickens love them (silver lining!)
Squash vine borers:
- Still learning how to prevent these jerks
- Lost some squash this year, trying again next season
Japanese beetles:
- They’re everywhere in July
- Testing companion plants that repel them
- Hand-picking gets old fast
Powdery mildew:
- Humidity + crowded plants = problem
- Learning about airflow and spacing
- Milk spray experiment coming soon
Weather Drama
- Spring frost surprises (covered plants at 10pm more than once)
- July/August heat (shade cloth saved my sanity)
- Too much rain OR drought (never just right!)
- Humidity (the root of most problems)
🌾 OTHER STUFF I’M TRYING
Berries (New Obsession)
- Growing Raspberries Series
My Tulamagi raspberry adventure with intercropping - Strawberries (planning to try next spring)
- Blueberries (researching varieties for Kentucky)
Herbs & Flowers
Working great:
- Thyme (variegated lemon thyme smells AMAZING)
- Marigolds (pest control + pretty)
- Basil (when it’s not too hot)
Still figuring out:
- Perennial herbs in clay soil
- Which flowers attract the BEST pollinators
- Keeping chickens out of flower beds (ongoing challenge)
Kentucky’s climate gives us a long growing season, but also throws some curveballs—like heavy spring rain, dense clay soil, July droughts or RAIN, and humidity that can wreck your tomato leaves overnight.
I garden in Zone 6b or 7A, depending on what grow chart is used, and here’s what that means in practice:
- You’ll plant cool-season crops as early as mid-March
- Summers are hot, humid, and stormy
- Clay soil holds nutrients, but needs major amending
- Shade, airflow, and organic mulch are your best friends
📌 RESOURCES I ACTUALLY USE
Where I get seeds:
- Epic Gardening (affiliate link – use BLOOMPECK5 for 5% off)
- Local seed swaps (when I remember to save seeds!)
- Experimenting with seed saving
Tools & supplies I recommend:
- (Building this list as I find what works!)
Local Kentucky resources:
- (Adding as I discover them!)
