If you’re searching for what to plant in May in Kentucky, you’re in the right place, and you are probably as excited as I am to dig in the dirt! May is THE month for Kentucky gardeners—frost risk is behind us, soil has warmed to 60°F+, and everything that’s been under lights finally goes outside. Here’s what to plant this month in zones 6b, 7a, and 7b across Western, Central, and Eastern Kentucky.
May in Kentucky means warm-season crops: tomatoes, peppers, beans, corn, squash, and cucumbers all go in the ground this month. If April was about patience, May is about ACTION.
See my complete, but in progress, [Kentucky Gardening Hub] for things I learn and share as I go.
I’m up here on the ridge in Columbia, Zone 7a, and the garden shifts completely this month—from cool-season to full warm-season mode.
🌱 We grow our own food to know exactly what goes into it—no guessing about pesticides or where it came from—and May is when the summer food production jumps into full action movie production!

What to Plant in May In Kentucky
May in Kentucky is primarily about warm season crops. I am so amped about planting this year. I am getting a small high tunnel put up! Can you say, extended season? Ok, we are putting it up so it won’t be fast, but still super excited about how this will extend our seasons.
🌱You will see most long time local gardeners say use The Kentucky Derby Rule — wait until the first Saturday in May. Most of central Kentucky’s last frost date falls right in that early May window. Western Kentucky can push a little earlier, Eastern Kentucky waits a little longer. But watch the weather, and if you do go in early, have cold-cover protection at the ready.
The big shift in May is soil temperature. Cool-season crops needed soil around 45–50°F. Warm season crops want 60°F minimum — and some like okra and sweet potatoes want even warmer than that. Don’t go by the calendar alone. Go by your soil thermometer. (I am going to love the raised beds for these sweet potato slips this year)

What if I Don’t Want to Start Seeds?
That is totally fine. May is actually a great month to direct sow a lot of warm season crops right into the ground — beans, corn, squash, cucumbers, and zucchini all go directly in the soil and don’t need to be started indoors first.
🌱 And just like April, your local Amish nurseries, farmers’ markets, and garden centers will have transplants ready and waiting. Don’t feel bad about buying starts — I do it too, especially with flowers or something new I want to try, but I am a little picky about who I buy from. The local growers are fantastic about answering questions, especially when I need to know what seeds and sprays are used.
What I’m Actually Planting in May — On My Kentucky Homestead
Here’s what is actually happening in my garden this month up here on the ridge in Columbia, Zone 7a. Your timing may shift a little depending on whether you are in western, central, or eastern Kentucky — but the general flow is the same.
Transplanting Out — Everything That’s Been Waiting
This is the big moment. Everything that has been sitting under lights in the basement or hardening off on the porch finally gets to go in the ground.
My tomatoes — German Pink, Kentucky Beefsteak, and San Marzanos — are going out once the soil hits 60°F and nights stay consistently above 50°F. I lost my Sungolds to a cold April night so I started a new round and I’m watching them closely. I love growing my own tomatoes, not only are fresh tomatoes AMAZING, I also get to control what goes into all my pasta sauces, pizza sauce, salsa, etc. See my complete guide to the best tomatoes for Kentucky for variety recommendations.
Peppers are going out this month too. I’ve been potting them up and they are strong — peppers hate cold soil even more than tomatoes so I’m waiting until nights are reliably warm before they go anywhere. [link to pepper post]
The cantaloupe and pickling cucumbers I started in April on the heat mat are heading to the new raised bed with the cattle panel trellis. The plan is cucumbers on one side of the trellis and Jack Be Little pumpkins on the other — we’ll see how that works out. I’ll report back.
🌱 And the big project this month — the high tunnel is going in. It’s been on order, and May is when we are installing it (if not sooner) We might be a little different; we did not go through the NCRS program to acquire our high tunnel. This isn’t for selling vegetables—it’s for extending our family’s growing season and having fresh tomatoes well into fall. We grow our own food to control exactly what goes into it, and the tunnel means more months of real, homegrown food for our table. I’m really hoping it arrives on schedule. More on that as it happens!
Direct Seeded Outdoors — Into Warm Soil
May is prime time for direct seeding warm season crops once soil temps hit 60°F.
Zucchini seeds are going directly in the ground this month — I started some indoors in April but zucchini actually does just fine direct seeded into warm soil and it catches up fast. I honestly may give a few away, as one will feed us just fine!
🌱 I’m also putting Jack Be Little pumpkin seeds to grow up the trellis as a special treat for my grandson. He loves the little pumpkins! And beans are going in this month too. I have Malibu Pole Bean, Kentucky Wonder, and Kentucky Blue Pole all ready to go. I am just going to plant one variety for Dilly Beans. Pole beans need something to climb, I may give the 3 sisters thing a try, or build a few wood pole set ups I just saw in my Rodale’s Gardening book. Bush beans like Jacob’s Cattle are going in as well — 88 days to harvest, so timing matters.
For corn I have Silver King and Cafe F1 — both go in mid to late May once soil is warm. This will be my first year planting corn here. I plan to plant them in a block, 4×4. I prepared the bed early this spring and have it covered to warm up that soil. I really really want to give that 3 sisters growing set up a test run.
I’m also direct seeding poppies, sunflowers, and nasturtium in my old raised beds along the fence near the garden for the pollinators this month. I found some Silvia, too at the Amish nursery I am going to plant. The bees are going to be obsessed.

And I can’t forget More Herbs! Dill, savory, cilantro, pineapple sage, tarragon. I found a new love for growing herbs since I started trying to have more control over our food.
What I’m Watching This Month
The high tunnel installation is the big one. Getting that structure up and the tomatoes inside is my main May goal. (We got it picked up April 21, 2025) I can’t wait to grow even more and extend our growing season. Having a say in what goes into our food makes my heart so happy!
I’m making sure the broccoli and onions are doing well under the bug net. My garlic transplants are also keeping me busy, they drink a lot of water since I had to move them for the high tunnel. Beyond that I’m watching soil temps closely before anything warm season goes in the ground — a week of warm days doesn’t mean the soil is ready.
I’m also watching the peas that went in back in March — they should be finishing up soon and I’ll tuck those cucumbers in beside them.
What NOT to Plant in May in Kentucky
May is too HOT for cool-season crops. Skip these:
Don’t Plant:
- Lettuce & Spinach — Will bolt immediately in May heat
- Peas — Season is over; they need cool soil
- Broccoli, Cabbage, Cauliflower — These went in March/April
- Radishes — Too hot (unless you want them to bolt for seed saving!)
Wait until August to start fall plantings of these cool-season crops.

This is an approximation with information from the UK Cooperative Extension. Kentucky is full of microclimates. For example, my kitchen garden things are colder than my ridgetop garden, and the holler is cooler yet. Check with your local extension office or look up your frost dates by zip code.

Frequently Asked Questions — What to Plant in May in Kentucky
Best Tomatoes to Grow in Kentucky: Zone 6 & 7May is your biggest planting month in Kentucky! Once frost risk passes (May 1-15 depending on zone), plant tomatoes, peppers, cucumbers, squash, zucchini, beans, corn, okra, melons, and pumpkins. Herbs like basil go in once nights stay above 50°F. Direct sow beans and corn straight into warm soil—they don’t need to be started indoors. See my complete guide to [when to plant tomatoes in Kentucky] for variety recommendations.
No! Late May is still fine for planting tomatoes in Kentucky. You’ll have 90-120 days until first frost (mid-October in Zone 7a, late October in Zone 7b). Most tomato varieties mature in 60-85 days, so you have plenty of time. You might miss the absolute earliest harvest, but you’ll still get a full tomato season.
According to the UK Extension office Publication 128, not at all. If you are just getting started in mid-May, you can still plant tomatoes, peppers, beans, squash, cucumbers, corn, and okra. I started zucchini at the end of May in 2025: it grew fast, I just had to watch for powdery mildew buildup. You have the whole warm season ahead of you. Make sure you check the maturity dates and see if the crops you chose are bolt-resistant too. The only crops you are genuinely too late for are cool-season crops like lettuce and spinach — those needed to go in back in March and April. But for everything warm season, you are right on time.
And July is coming for that Fall Garden!
The Kentucky Derby Rule is a traditional guideline Kentucky gardeners have used for generations: wait until the first Saturday in May (Derby Day) as your minimum safe date for planting warm-season crops like tomatoes and peppers. This timing coincides with when frost risk has passed in most of central Kentucky. Western Kentucky can plant a week earlier; Eastern Kentucky waits until mid-May. Always check your local frost dates and soil temperature (60°F minimum) before planting.
The 70/30 rule is a simple guideline that suggests planting about 70 percent of your garden with reliable crops you know grow well in your climate, and reserving 30 percent for experimenting with something new. It protects your harvest while still leaving room to try new varieties and learn. Honestly this is exactly how I approach my Kentucky garden — my reliable cool season crops anchor April, and the sweet potato slip timing experiment I’m running this month? That’s my 30 percent. 😄
