Spring is in full swing, and May is one of the busiest months for gardeners across the United States. Whether you’re in a warm southern zone or still seeing frost in the north, there’s plenty to do to get your garden growing strong.
Here’s your May gardening checklist, organized by USDA Plant Hardiness Zones, to help you stay on track. Plus, we’ll share a few natural gardening solutions to boost your soil health and plant vitality along the way.
Zones 3–5: Gearing Up for Full Planting Season
Average Last Frost: Late April to Mid-May
Garden Tasks:
- Start planting warm-season crops like tomatoes, beans, cucumbers, and squash once danger of frost has passed.
- Direct sow hardy vegetables like carrots, beets, lettuce, and spinach.
- Prepare soil beds with organic compost and improve microbial life using Ecoworm Soil Extract.
- Prune shrubs and perennials as they begin to show new growth.
- Mulch beds to retain moisture and reduce weeds.
- Monitor for early pests like aphids—use Ecoworm Potassium Soap, a natural garden soap, to help plants thrive without synthetic chemicals.
Zones 6–7: Full Steam Ahead
Average Last Frost: Late March to Early April
Garden Tasks:
- Plant tomatoes, peppers, corn, and melons now that soil is warm.
- Feed soil and seedlings every 2-3 weeks with organic liquid fertilisers like Ecoworm’s Soil and Sapropel Extracts.
- Thin out seedlings for proper spacing.
- Weed control is essential – get ahead now before summer growth explodes.
- Deadhead spring blooms and prune flowering shrubs after they finish blooming.
- Aerate and feed your lawn – Ecoworm Soil Extract works wonders on turf health.
Zones 8–10: Maintain, Mulch, and Harvest
Average Last Frost: February to Early March
Garden Tasks:
- Harvest early spring crops like lettuce, spinach, and radishes.
- Plant heat-loving crops like okra, eggplant, sweet potatoes, and watermelons.
- Protect soil moisture with mulch—especially in hot zones like Texas and Florida.
