What to Plant in April (2026 Edition) Your Texas Garden Guide — Houston, Austin, Dallas & Beyond

April is one of the most pivotal gardening months in Texas. What you plant — and what you let go of — this month determines how your entire summer garden performs.

If you followed along with the March planting guide and got your cool-season crops in, this post is your next step: looking ahead to summer and making sure your warm-season garden is set up well.

And if you haven’t started anything yet — this is your push. It’s not too late. But the window is moving, and knowing your region’s specific timing makes all the difference.

Let’s get into it.

Why April Is Different From Every Other Month

April sits in a real transition zone in Texas. Cool-season gardening is winding down. Warm-season gardening is either already underway or about to be. And four things are happening simultaneously that make this month require its own approach:

• Soil temperatures are rising fast. Warm-season crops need soil above 60–65°F to germinate and establish well. In Houston we hit that in early April. In Austin, Dallas, and El Paso, it takes a little longer — and knowing your specific window matters more than the date.
• Cool-season crops are finishing. Lettuce, cilantro, spinach, and peas are sensing the shift in daylength and temperature. Even if they still look okay, they’re beginning their end-of-cycle stress response. Holding on past their peak costs you bed space you need right now.
• Pest pressure is beginning. Aphids, caterpillars, squash vine borers — they wake up with the warmth. April is when you get ahead of this, not when you react to it in June.
• Your summer window is already open. For Dallas and El Paso, the ideal transplant window for tomatoes and peppers opened in late March. If you’re reading this in April, you need to move this week — not next weekend.

The Bolting Lesson: What I Learn Every April

Every April, without fail, I let my lettuce bolt.

Every single year. Early April arrives, I know the lettuces are on their way out, I get busy thinking about warm-season crops and moving compost and preparing beds — and by the time I get back to them, the center stalk has already shot up. The leaves have turned bitter. The harvest window is closed.

Produce I grew and didn’t get to enjoy. It stings every time.

So if you have lettuce, spinach, or peas still in the ground right now: go harvest them this week. Once daytime temperatures consistently hit 75°F or above, bolting accelerates quickly and the flavor goes with it.

But here’s the distinction I want you to carry into this month:

Lettuce bolting = a harvest you missed. Herb bolting = a strategy you chose.

I let my herbs bolt on purpose every season. When my cilantro sends up its flower stalk, when my basil starts to bloom — I leave it. Those flowers are covered in pollinators. Every bee and butterfly in the garden finds them, and that activity moves through the whole growing space — my tomatoes, peppers, and squash all benefit. And once the flowers finish, I collect the seeds for fall planting.

Same word. Completely different outcome depending on which plant you’re talking about. Know the difference, and April becomes a lot more intentional.

Houston & Gulf Coast (Zone 9B): What to Plant in April

Houston, you are in the most favorable position. Your soil is warm across the entire month, your frost is well behind you, and you have a full window to plant aggressively. Don’t wait.

Warm-season vegetables: Tomatoes (transplants only — cherry varieties like Sweet 100 and Sun Gold hold up best in our summers), hot peppers, eggplant, cucumbers (give them a trellis from day one), summer squash, bush and long beans, okra (direct seed now), corn (plant in blocks), watermelon and cantaloupes, and roselle — a tropical hibiscus that thrives in our heat and produces calyxes for hibiscus tea in fall.

Herbs: Basil (seed or transplant, plant generously near your tomatoes), oregano, thyme, and rosemary (transplant preferred).

Companion flowers: Sunflowers, zinnias, marigolds near tomatoes and peppers, borage, and nasturtiums (early April is better while conditions are still cooler).

What to phase out now: Cilantro, lettuce, spinach, and peas. Pull them, compost them, and use that bed space for something that wants to grow in the heat.

Austin & Central Texas (Zone 8B–9A): April Planting Windows

Austin’s last frost date is March 18, so by April you’re fully in warm-season territory — but with a slightly narrower window than Houston before summer heat sets in. Move with intention this month.

• Tomatoes: Transplant April 1–8. Your most urgent task.
• Peppers & eggplant: Transplant April 1–8.
• Cucumbers: Transplant through April 8, or direct seed from April 1.
• Summer squash & zucchini: Transplant through April 8, or direct seed from April 1.
• Green beans: Direct seed through April 15.
• Okra: Transplant April 1–8, or direct seed April 1–15.
• Sweet corn: Direct seed April 1–15. Plant in blocks.
• Melons: Transplant or direct seed April 1–8.
• Basil: Transplant or direct seed April 1–15.
• Cilantro: Last recommended date is April 8. If it bolts quickly, let it — the flowers will feed your pollinators.

Dallas & North Texas (Zone 8A): Your Window Opened in March

Dallas’ last frost date is March 9 — which means your warm-season planting window opened in late March. If you’re reading this in April and haven’t planted tomatoes yet, you need to move this week.

• Tomatoes: Ideal transplant window was March 23–30. Get them in the ground immediately if you haven’t.
• Peppers & eggplant: Same window. Transplants in now.
• Cucumbers: Direct seed March 23–30. Early April seeding still works but don’t delay further.
• Summer squash & zucchini: Same timing as cucumbers.
• Green beans: Direct seed window runs through April 6. Still a solid window.
• Okra: Direct seed March 23–April 6. More flexibility here.
• Sweet corn: Direct seed March 23–April 6.
• Melons: Transplant or direct seed March 23–30. Plant this week.
• Cilantro: Last recommended date was March 30. If it’s already in the ground and bolting, let it go — collect the coriander seed for fall.

El Paso & West Texas (Zone 8A, 3,917 ft elevation): Dry Heat Gardening

El Paso shares a last frost date with Dallas (March 9), but nearly 4,000 feet of elevation changes everything. Your heat is dry, your overnight temperatures drop further, and your primary challenge is moisture retention — not humidity or disease.

• Tomatoes & peppers: Transplant window March 23–30. Move this week if you haven’t.
• Cucumbers & squash: Direct seed March 23–30. Early April still viable.
• Green beans: Direct seed through April 6.
• Melons: Watermelon and cantaloupe thrive in dry heat with consistent irrigation. Plant March 23–30.
• Sweet potatoes: Transplant window March 30–April 6. A great El Paso option right now.
• Okra: Direct seed March 23–April 6.
• Herbs: Oregano, thyme, and rosemary are all well suited to dry heat.

Most importantly: set up your drip irrigation before seeds go in. In West Texas, your water management plan is your planting plan.

The Simple April Formula

If you’re feeling overwhelmed by everything on this list, come back to the formula that works every single season:

Start with 1–2 vegetables + 1–2 herbs + 1–2 flowers. That’s a complete summer garden.

A focused garden that you actually tend will outperform an overstuffed one every time. Cherry tomatoes, long beans, basil, and zinnias — that’s four plants. That’s a productive, pollinator-friendly, joyful summer garden.

Start there. Expand next season.

A Quick Word on Soil

Before you plant anything, take a moment to think about what your plants are going into.

Most Houston-area gardeners are working with heavy clay soil — which compacts easily, holds water unevenly, and can stress young transplants as April temperatures rise. The single best thing you can do before planting is amend your soil.

• Add compost — it breaks up clay and feeds plants organically
• Consider raised beds if you’re starting fresh — full control over your growing medium
• Mulch your soil surface to hold moisture and protect roots as summer arrives

Healthy soil grows healthy plants. It always starts there.
