What to Plant in Phoenix in June
June is when Phoenix earns its reputation. Temperatures climb past 110°F, soil surface temperatures reach 150°F in direct sun, and the vast majority of vegetables simply cannot survive. This is not a failure of your gardening — it's physics. Here's what can grow, what to do with your beds, and how to set yourself up for a great October fall garden.
What Can Actually Grow in Phoenix in June
This is a short list, and most of these plants look at our summer heat as an invitation rather than a threat:
Okra
The undisputed king of Phoenix summer gardening. Okra doesn't just tolerate 110°F heat — it thrives in it. If you planted in April or May, June is when okra production ramps up. Pick pods every 2–3 days when they're 3–4 inches long (they get tough and fibrous if left longer). Production accelerates as summer continues.
Armenian Cucumber
Technically a melon, but used like a cucumber. Much more heat-tolerant than regular cucumbers. If planted in April–May, it's producing now. Needs consistent water and some afternoon shade in the hottest weeks, but can produce through July.
Eggplant
Eggplant is a phoenix of the Phoenix garden — it often looks stressed during the worst heat but bounces back and produces steadily. Keep it well-watered with drip and mulch heavily around the base. It will reward you with production all summer and into fall.
Sweet Potato Vines
Already in the ground since April or May, sweet potato vines spread as low-maintenance ground cover through summer. Keep drip running and let them grow. Harvest the tubers in September–October. The leaves are also edible as greens.
Malabar Spinach
A tropical vine that tolerates heat most greens can't touch. Not the same flavor as regular spinach, but heat-tolerant and productive in summer. Plant in June and harvest leaves through summer.
Amaranth
Both edible and ornamental. Thrives in June heat. The leaves are edible as cooked greens; the seeds are edible as grain. Direct sow now.
Most Gardeners: Rest the Beds
If you're not pursuing heat-lovers, the smart June move is garden maintenance:
- Mulch empty beds 3–4 inches deep — protects soil from sun, keeps it cooler, preserves beneficial soil organisms
- Keep drip running — Even resting beds benefit from occasional moisture to keep soil life alive
- Order fall seeds now — Summer is a great time to plan your October garden when you're not busy planting
- Refresh compost — Add a fresh layer to beds you'll plant in October; let it break down over summer
