What to Plant in June in Zone 8b Texas

June in Zone 8b Texas is when the garden separates winners from quitters.

The lettuce is gone. The peas are crispy. Highs are pushing 95°F by mid-month, and the soil is officially too warm for most spring crops. But this is also when okra hits its stride, peppers start setting heavy fruit, and your tomato vines are dripping.

Here's what we plant in June, what we keep alive, and what we start dreaming about for fall.

What June Looks Like in Zone 8b

By June 15, you can expect:

Daytime highs of 92-98°F, climbing toward triple digits
Soil temps of 80-85°F at planting depth
Almost no rainfall (or torrential storms — no in-between)
Tomato fruit set slowing as nights stay above 75°F

Plant accordingly. The crops that thrive now are heat-adapted, drought-tolerant, and originate from places way hotter than Vermont.

What to Direct Sow in June

The list is short — and that's okay:

Heat champions

Okra (still excellent through June 15)
Black-eyed peas / cowpeas (love the heat)
Yard-long beans / asparagus beans
Sweet potato slips (last good window — get them in by June 10)
Pumpkins for fall harvest (sow by June 30 for October pumpkins)
Winter squash (butternut, acorn — also for fall)

Herbs

Basil (still going strong)
Lemongrass
Mexican mint marigold (replaces tarragon in our heat)

Greens that can take it

Malabar spinach (not real spinach but a heat-loving climbing vine — delicious)
New Zealand spinach (same idea)
Sweet potato greens (yes — the leaves are edible and excellent)
Amaranth
Molokhia (Egyptian spinach — a hidden gem in Texas summer)

Timing tip: Pumpkin and winter squash sown in June will be ready right around Halloween. Most people don't realize Texas can grow pumpkins — June is the month to make it happen.

What to Transplant in June

The transplant window is mostly closed for warm-season crops. But you can still tuck in:

Sweet potato slips (last call by June 10)
Heat-tolerant pepper varieties (jalapeños, serranos, Anaheims) — they keep producing
Eggplant (still doing well)
Okra plants if you missed seeding

Don't waste money on tomato transplants in June. They won't set fruit reliably until temperatures drop in September.

What's Still Producing

This is when your spring investment pays off:

Tomatoes: Picking daily. Watch for blossom drop above 92°F — that's normal, not a problem.
Peppers: Heavy fruit set. Pick regularly to encourage more.
Cucumbers: Last few weeks before powdery mildew shuts them down.
Summer squash and zucchini: Picking every 1-2 days.
Eggplant: Just hitting stride.
Beans: Bush beans winding down, pole beans still going.
Herbs: Basil thriving. Rosemary, thyme, oregano all unbothered.

Start Fall Tomatoes Now

This is the secret of Zone 8b gardening: start seeds for your fall tomato crop in early June.

Yes, while it's 95°F outside.

The math works out:

Seed indoors June 1-7
Transplant in mid-July (yes, in 100°F — with shade and care)
Harvest in September-October

Fall tomatoes in Zone 8b are often better than spring. The plants are mature, the weather is moderating, and the bugs have moved on. Don't skip this.

How to Survive Summer Watering

June is when watering becomes a job.

The non-negotiables:

Drip irrigation, not overhead
Deep soak 2-3 times a week (not light daily watering)
3+ inches of mulch on every bed
Water before 9am, every time
Check pots and small beds twice daily — they dry out fast

The mistakes to avoid:

❌ Watering at noon (the water evaporates before it hits the roots)
❌ Watering leaves (fungal disease city)
❌ Letting beds go bone-dry between waterings (stress = no fruit)

A simple drip kit with a $20 Orbit timer pays for itself in the first week of triple-digit heat.

Use Shade Cloth

If your beds get afternoon sun (south or west exposure), you need shade.

30-40% shade cloth over your most heat-stressed beds will:

Drop soil temp by 5-10°F
Cut water evaporation in half
Keep tomato fruit from sun-scalding
Buy you another month of leafy production

We use 50% shade cloth clipped to PVC hoops over our most exposed beds. Cheap, effective, comes off in October.

Our June Planting Schedule

Week 1 (June 1-7): Start fall tomato seeds indoors. Direct sow pumpkins, winter squash, malabar spinach. Last sweet potato slips.

Week 2 (June 8-14): Mulch every bed. Set up shade cloth. Direct sow more okra, cowpeas.

Week 3 (June 15-21): Start fall pepper seeds (yes, also now). Plant heat-tolerant herbs. Begin succession of basil.

Week 4 (June 22-30): Maintain. Harvest aggressively. Plan fall garden layout while you're inside avoiding the heat.

What You'll Be Harvesting

Early June: Last cucumbers, peak summer squash, first heavy tomato harvests
Mid June: Tomato peak, peppers building, eggplant starting
Late June: Okra coming on strong, beans winding down, basil pesto-worthy

The Mindset Shift

June is when most new Zone 8b gardeners give up. The lettuce is dead, the spinach bolted, and they think the season is over.

It's not. It just changed teams.

Switch to the heat-lovers, mulch deeply, water smart, and start your fall garden indoors. You'll have okra in July, pumpkins in October, and tomatoes again in September.

Don't quit on your garden in June. The best is still coming.
