What Is Considered Early Summer?
Defining the Term
In gardening terms, early summer typically refers to the transition period between late spring and the full onset of summer. This usually occurs:
- From late May to mid-June in most of the United States
- When daytime temperatures consistently reach 70°F to 85°F
- After the last frost date but before peak summer heat
“Early summer is a sweet spot for gardeners—warm enough for growth, but not too hot to stress plants.” — Gardeners of America
USDA Zones and Early Summer
| USDA Zone | Approx. Early Summer | Notes |
|---|---|---|
| Zone 3–4 | Early June to Mid-June | Short growing season |
| Zone 5–6 | Late May to Early June | Optimal planting window |
| Zone 7–8 | Mid-May to Early June | Heat-tolerant crops thrive |
| Zone 9–10 | May | Warm-weather plants already in bloom |
Why Early Summer Matters for Gardening
Critical Time for Planting and Maintenance
Early summer is crucial because it’s:
- The ideal time for planting summer vegetables and flowers
- A period when soil temperatures are warm enough for rapid root growth
- Prime time to fertilize, water deeply, and prepare for mid-summer heat
Seasonal Milestones
- First fruits begin forming (e.g., strawberries, peas)
- Flowering annuals enter active bloom
- Warm-season pests and weeds become active
What to Plant in Early Summer
Vegetables
| Crop | USDA Zones | Tips |
|---|---|---|
| Tomatoes | 5–10 | Choose heat-tolerant varieties |
| Peppers | 6–10 | Mulch to retain soil moisture |
| Squash | 3–10 | Direct seed in warm soil |
| Beans | 3–10 | Fast growers for succession planting |
Flowers
- Zinnias – Quick to bloom, heat-loving
- Marigolds – Pest repellent, colorful
- Cosmos – Thrive in full sun and low water
Herbs
- Basil – Loves heat
- Cilantro – Bolt-resistant varieties recommended
