Every May, I can feel North Texas waking up in full color. The mornings are warm, the soil is alive, and those unpredictable spring rains finally start to settle down. It’s that golden window where the weather’s just right — not too hot yet, but warm enough for your plants to really take off.
If you’re anything like me, you probably start May with dirt under your nails and excitement in your heart, wondering what can I still plant now? Believe me, I’ve been there — juggling seedlings, checking soil temps, and racing the Texas heat. Some folks care more about vibrant color; others, like me, are torn between the joy of fresh herbs and the satisfaction of a bountiful veggie patch.
Over the years, I’ve tested, failed, and triumphed through countless Texas Mays. From watching my okra explode under the sun to learning the hard way that lettuce bolts faster than you can blink, I’ve picked up a lot of practical know-how. That’s why I wanted to share this guide — to save you the trial and error and help your garden thrive in this unique climate.
So grab your gloves and a cold drink — I’ll walk you through what to plant in May in North Texas, complete with my personal favorites, care tips, and a handy chart you can use year after year.

🥒 Vegetables That Love May Heat
1. Okra: The True Texan’s Summer Warrior
I’ll be honest — I used to underestimate okra. Then one May, I stuck a few seeds in the corner of a bed, and by July, I had a forest. Okra thrives in the Texas sun, even when other veggies wilt.
My tip: Don’t baby it with rich compost. Okra prefers moderately poor soil and can handle dry spells. Just make sure it gets full sun — 6 to 8 hours daily — and harvest pods while they’re young (3–4 inches) before they toughen up.
If you’re curious about companion planting, okra pairs wonderfully with peppers and basil. (You can read more in my post on how to grow peppers successfully in North Texas.)
2. Southern Peas: Reliable, Resilient, Rewarding
Black-eyed peas and purple hull peas are some of my favorite May plantings. They don’t just tolerate heat — they celebrate it.
These legumes enrich your soil with nitrogen while producing delicious pods. I usually direct-sow them right into my beds around mid-May, once the soil’s nice and warm. They’ll germinate fast and sprawl happily.
Pro tip: Don’t bother fertilizing them; they make their own nitrogen. And for pest control? Marigolds nearby help repel nematodes naturally.
3. Sweet Potatoes: Beauty and Function
Sweet potatoes are the dual-purpose gem of the summer garden — edible roots underground and lush vines above. They spread beautifully, making a great edible groundcover.
In May, plant slips, not seeds. I’ve had great success with varieties like Beauregard and Georgia Jet. Once planted, they need very little care except consistent watering early on.
Come fall, you’ll dig up a treasure trove of roots. Honestly, few crops give me as much satisfaction as harvesting sweet potatoes I planted in May.
4. Eggplant: Glossy, Gritty, Gorgeous
Eggplants are finicky early on but unstoppable once established. I usually transplant healthy seedlings in early May when nighttime temps stay above 60°F.
Tip from experience: Use mulch generously. Eggplants hate root stress, and mulch keeps the soil evenly warm and moist. Also, give them room — about 24 inches apart.
Their deep purple blooms are ornamental too, making them a lovely addition even in decorative beds.
5. Peppers: Sweet or Spicy, They Love It Hot
By May, pepper seedlings hit their stride. Whether you prefer jalapeños or bell peppers, both do beautifully in North Texas’ warm soil and long days.
I’ve noticed my peppers produce best when I prune off the first few flowers — it encourages stronger root growth. Keep them mulched and watered deeply twice a week.
Peppers are slow to start but unstoppable once summer hits full swing. If you want a steady supply, stagger plantings every two weeks through late May.
🌿 Herbs for May Planting in North Texas
6. Basil: The Queen of the Texas Kitchen Garden
Every May, I plant at least three types of basil — sweet, Thai, and lemon. Basil loves North Texas heat, as long as it gets regular water.
Here’s my biggest basil secret: pinch off any flower buds as soon as you see them. This keeps your plant producing tender, flavorful leaves.
I also grow basil next to tomatoes to deter hornworms naturally — a little gardener’s hack that’s never failed me.
7. Oregano: The Lazy Gardener’s Best Friend
Oregano might just be my favorite “plant it and forget it” herb. Once established, it laughs at drought and keeps giving for years.
In May, start with a small nursery plant and let it spread. I like to grow oregano along the sunny edges of my raised beds — it softens the borders and fills the air with fragrance.
If you ever need a quick seasoning boost, just snip a few sprigs. Oregano’s flavor actually intensifies in the heat!
8. Rosemary and Thyme: Evergreen and Ever Reliable
Though these herbs prefer cooler starts, May-planted rosemary and thyme will still take off if you give them well-draining soil.
My advice: Avoid heavy clay. Mix in sand or perlite. Once they root, they’ll endure the hottest July days without complaint.
Rosemary also doubles as a pollinator attractor — bees absolutely adore it. You can read more about that in my article on Texas-friendly plants for pollinators.
🌸 Flowers to Brighten Your May Garden
9. Zinnias: Instant Color, Zero Fuss
If there’s one flower I’ll always recommend for a North Texas May, it’s zinnias. They’re heat-loving, drought-tolerant, and bloom nonstop till frost.
I scatter seeds directly into garden beds, and within weeks, I’m rewarded with bright pinks, oranges, and yellows. Zinnias are also butterfly magnets — I often see monarchs and swallowtails fluttering around them all summer.
Pro tip: Deadhead regularly for continuous blooms.
10. Marigolds: Pest Control in Disguise
Marigolds aren’t just beautiful; they’re strategic. Their strong scent deters aphids, nematodes, and whiteflies, which makes them perfect companions for tomatoes, peppers, and beans.
Plant them in May, and they’ll last through October. I love how they make my veggie garden look cheerful while protecting it.
For large beds, I like the African Marigold varieties — tall and showy. For borders, French Marigolds stay compact and tidy.
11. Sunflowers: The Giants of Summer
Nothing captures the Texas summer spirit quite like a sunflower. I plant seeds in late May along fences or the back of my garden.
They love heat, thrive in poor soil, and attract bees and birds. The only trick is space — tall varieties need staking or wind protection.
If you’re short on space, try dwarf sunflowers like Teddy Bear — they’re just as charming but easier to manage.
12. Portulaca (Moss Rose): Drought-Proof Beauty
For hot, dry spots that fry everything else, portulaca is a lifesaver. Its bright, almost neon blooms open every morning and close at night — a small daily delight.
I grow it in rocky soil where nothing else survives. Once established, it needs almost no care. Believe me, this plant will forgive your neglect in the heat of summer.
13. Periwinkle (Vinca): The Ultimate Heat Champion
If I had a dollar for every time vinca saved my summer garden, I’d have a lot of mulch money. It’s practically indestructible once established.
Plant in May, and it will bloom nonstop until the first frost. Just avoid overwatering — vinca likes it dry and sunny.
I love pairing white and pink varieties around pathways for a clean, classic look.
🥒 Bonus Picks for May
If you’ve still got room, try cucumbers and summer squash. Both take off fast in warm soil and reward you within weeks.
Cucumbers need trellising to save space and improve air flow (reducing powdery mildew), while squash benefits from frequent harvesting to stay tender.
Pro tip: Interplant marigolds nearby — they’ll help repel cucumber beetles naturally.
🌤️ Expert Notes and Regional Advice
After years of planting in North Texas (I’m in Zone 8a, for the record), here are a few hard-earned lessons I’ve learned:
- Watch the weather: May can swing from cool rain to 95°F in a week. Always check the soil temperature (ideally above 65°F) before direct-sowing seeds.
- Mulch is your best friend: It keeps moisture consistent and soil temps stable. I use shredded hardwood or straw around most plants.
- Don’t over-fertilize: Especially for heat-loving crops like okra and peas. Too much nitrogen gives you big leaves but fewer fruits.
- Water deeply, not often: Shallow watering creates weak roots. Two deep soakings per week usually beats daily sprinkling.
- Shade cloth helps: For young seedlings, a bit of afternoon shade (or 30% shade cloth) can prevent transplant shock.
- Mind your pests: May is when aphids, spider mites, and caterpillars wake up. Neem oil or insecticidal soap does wonders if used early.

🌻 Conclusion: Wrapping Up My May Garden Story
May is one of my favorite gardening months in North Texas. It’s that sweet spot between spring and summer where everything feels possible — when your beds are full of life, bees buzz around, and new blooms appear almost overnight.
I still remember my first May garden years ago — a chaotic mix of basil, zinnias, and a few scraggly pepper plants. But over time, I’ve learned that May is more forgiving than it seems. With the right choices, you can set up your garden to flourish through the hottest months ahead.
So whether you’re planting your first okra seed or experimenting with sunflowers by the fence, trust the rhythm of the season. North Texas may be unpredictable, but it rewards those who plant with patience and heart.
