May is a great month to plant a variety of warm-season crops in your Houston backyard garden. With average temperatures climbing into the 80s and plenty of sunshine, USDA Zone 9 provides an ideal growing environment for both vegetables and herbs. Here are some top crops to consider planting in May:
1. Okra
Okra thrives in Houston’s heat and can handle the hot, humid summer ahead. Sow seeds directly into the garden in full sun. Harvest the pods frequently while they are young and tender.
2. Sweet Potatoes
May is an excellent time to plant sweet potato slips. They need loose, well-drained soil and lots of space to sprawl. These heat-loving tubers will mature in about 90 to 120 days.
3. Southern Peas (Black-eyed peas, Crowder peas)
Southern peas love the heat and are drought-tolerant, making them perfect for Houston summers. Sow seeds directly in the garden for a late summer harvest.
4. Peppers (Bell, Jalapeño, Banana)
If you missed planting peppers in early spring, you can still transplant established seedlings in early May. They need full sun and consistent watering to thrive.
5. Eggplant
Like peppers, eggplants love warm soil. Transplant young plants into your garden beds and provide support as they grow. Watch for flea beetles and other pests.
6. Basil and Other Herbs
Basil, oregano, thyme, and mint grow well in the heat of May. Basil especially flourishes and benefits from frequent harvesting, which encourages bushier growth.
7. Malabar Spinach
This heat-tolerant leafy green thrives where regular spinach wilts. It climbs easily, so give it a trellis and enjoy fresh greens throughout the summer.
8. Yardlong Beans (Asparagus Beans)
These vigorous climbers do well in the Houston heat and produce long, tender pods. Direct sow and provide a trellis or fence for support.
Tips for Success:
- Mulch: Apply mulch around plants to retain moisture and suppress weeds.
- Water: Houston heat dries soil quickly. Water deeply and early in the morning.
- Watch for pests: Aphids, squash bugs, and caterpillars can appear this time of year. Monitor plants regularly and use organic pest control methods when possible.
May is a transitional month for gardening in Houston. With the right crops and care, your backyard garden can thrive and provide fresh produce all summer long.
