Warm-Season Vegetables Perfect for Atlanta’s May Weather

May in Atlanta means the risk of frost is long gone, and warm, humid days are in full swing. This is the time to focus on heat-tolerant crops that will thrive in USDA Zone 8. With warm soil, frequent rain, and long daylight hours, it’s a prime month for summer vegetables to get established and flourish.

Top Vegetables to Plant This Month

If you’re wondering what to plant in Atlanta gardens in May, these warm-season vegetables are the top picks for vigorous growth and high yields:

Tomatoes: Indeterminate varieties offer longer harvests; plant deeply and provide sturdy stakes or cages for support. Look for disease-resistant types suited to Georgia’s climate.
Peppers: Bell peppers, jalapeños, and other hot varieties thrive in Atlanta’s heat and rich soil.
Beans: Both bush and pole beans do well in late spring; succession plant every few weeks for a steady supply.
Okra: A Southern staple, okra is drought-tolerant and grows tall, producing pods well into summer.
Squash & Zucchini: Fast-growing and prolific; give these plants plenty of room and monitor for squash bugs and powdery mildew as the season progresses.

What About Greens?

Cool-season greens like spinach and arugula are past their peak by May, but heat-tolerant alternatives keep Atlanta gardeners harvesting all summer:

Malabar Spinach: This vining, tropical green flourishes in heat and humidity and is perfect for summer salads and sautés.
Swiss Chard: Handles warmth better than lettuce or kale and offers colorful stems that brighten the garden bed.

Tips for May Garden Success in Atlanta

Soil Prep: Mix compost and well-aged manure into heavy Georgia clay to improve drainage and boost fertility. Consider a soil test to check pH (aim for 6.0–6.8 for most vegetables).
Water Early & Often: Deep watering at the base of plants in the early morning helps establish strong roots and minimizes evaporation. Atlanta’s May heat can dry soil quickly—mulch generously to lock in moisture.
Mulch Matters: Apply straw, pine bark, or leaf mulch around plants to suppress weeds and regulate soil temperature. This also prevents soil from splashing onto lower leaves during heavy rain.
Pest Watch: Scout regularly for aphids, caterpillars, and squash bugs—handpick or use organic sprays as needed.

Planning for a Summer Harvest

Stagger plantings of quick-maturing crops like beans and summer squash for a longer, continuous harvest. For tomatoes and peppers, mix early, mid-, and late-season varieties to spread out picking and avoid gluts. With proper planning, your Atlanta garden will yield fresh vegetables well into the hot summer months.
