What to Plant in Phoenix in April
April is the best month in the Phoenix garden. Tomatoes are ripening, cucumbers and squash are producing daily, and temperatures are still comfortable. This is what you planted for back in January and February — enjoy it. There's very little to plant in April; the focus is harvest.
What's Producing in April in Phoenix
If you planted on schedule, April is your payoff month:
- Tomatoes — Peak production. Pick daily as fruit ripens. The more you pick, the more the plant produces.
- Cucumbers — Extremely productive in April. Pick every 2–3 days or they'll get too large and turn bitter.
- Summer squash and zucchini — Daily picking required. One day too long and a zucchini becomes a baseball bat.
- Peppers (all types) — Producing well. Green peppers can be picked early or left to ripen to red/yellow for sweeter flavor.
- Green beans — At or approaching harvest. Pick pods when fingers are visible but before seeds bulge.
- Eggplant — Producing steadily and will continue into summer better than most crops.
What to Plant in April in Phoenix
The spring planting window has closed for most crops, but a few things still go in April:
Basil
Basil thrives in April warmth. Direct sow seeds or transplant from a nursery start. Pinch off any flower heads as they appear to keep plants leafy and productive. Basil and tomatoes are natural companions in the garden and on the plate.
Okra
April is prime time to start okra. It loves heat and is one of the few crops that actually improves as Phoenix temperatures rise through summer. Direct sow seeds 1 inch deep, 18 inches apart. Expect first harvest in June–July and production all summer.
Armenian Cucumber
Not actually a cucumber — it's a melon — but it tastes like cucumber and tolerates Phoenix summer heat far better. Plant seeds in April and it will bridge the gap between spring cucumber season and summer, producing through June and July when regular cucumbers have given up.
Sweet Potato Slips
Plant sweet potato slips in April–May. They grow as a sprawling ground cover through summer, tolerate extreme heat, and are harvested in fall. The vines are also edible as greens. Good use of garden space during the months when most crops can't grow.
What April Signals: Prepare for Summer
April is also the time to start thinking ahead. In 6–8 weeks, most of your spring crops will be finished. Start planning:
- What beds will you rest through summer?
- Will you try any summer heat-lovers (okra, sweet potatoes, Armenian cucumber)?
- Stock up on compost to refresh beds in late summer before the October fall planting window.
