This guide will explore the best things to plant in May, focusing on specific recommendations for each USDA zone to ensure your garden thrives.

Vegetables To Plant

Tomatoes

Tomatoes are a quintessential vegetable for home gardens, and May is the perfect month to plant seedlings in USDA zones 5-10. When the soil temperatures reach at least 60°F and all danger of frost has passed, initiate your planting. Choose determinate varieties like ‘Early Girl’ for compact growth if you’re short on space or indeterminate types like ‘Brandywine’ for a bigger harvest throughout the season. Tomatoes prefer full sun, ideally receiving 6-8 hours daily. Regular watering is essential, especially as fruit develops—aim to keep the soil consistently moist but not soggy. Use mulch to retain soil moisture, reduce weeds, and maintain even soil temperatures. With careful nurturing, you can expect your first harvest about 75-90 days after planting.

Cucumbers

Cucumbers are another warm-weather crop that thrives when sown in May across USDA zones 3-10. They enjoy temperatures ranging from 70-95°F.
