Cool Season Crop Guide

Cool-season champions prefer temperatures between 50-70°F and can tolerate light frosts. Plant them 2-4 weeks before your last frost date for best results.

Early Spring Plantings (6-8 weeks before last frost)

  • Onion sets and transplants - Plant as soon as soil can be worked
  • Garlic - Actually planted in fall, harvested in spring
  • Fava beans - Cold hardy, nitrogen-fixing
  • Peas (snap and snow) - Direct sow, provide support

Mid-Spring Plantings (2-4 weeks before last frost)

  • Lettuce - Mix of varieties for extended harvest
  • Spinach - Bolt-resistant varieties for spring
  • Radishes - Quick growers, succession plant every 2 weeks
  • Carrots - Direct sow, thin carefully
  • Beets - Edible roots and greens
  • Swiss chard - Cut-and-come-again harvest

Late Spring Plantings (last frost date)

  • Broccoli - Transplants preferred over direct seeding
  • Cabbage - Long season crop, plan for fall harvest
  • Kale - Heat-tolerant varieties for spring planting
  • Arugula - Quick growing, spicy greens

Warm Season Crop Guide

!Warm season warning

These crops are killed by frost and prefer temperatures above 60°F. Wait until soil temperature reaches 60°F or higher before planting.

Early Warm Season (2 weeks after last frost)

  • Beans (bush and pole) - Direct sow, succession plant
  • Corn - Plant in blocks for pollination
  • Squash (summer) - Zucchini, yellow squash, pattypan
  • Cucumbers - Provide trellises for space saving

Mid-Season Warm Crops (3-4 weeks after last frost)

  • Tomatoes - Transplants only, support with cages/stakes
  • Peppers - Transplants, wide variety of heat levels
  • Eggplant - Long season, heat-loving
  • Basil - Perfect companion for tomatoes

Late Season Heat Lovers (4+ weeks after last frost)

  • Okra - Thrives in hot weather
  • Sweet potatoes - Long season, plant slips
  • Hot peppers - Superhots need extra warmth
  • Melons - Need consistent heat and space

2026 Succession Planting Schedule

Succession planting extends your harvest season and ensures fresh produce all season long. Here is your 2026 succession schedule by interval.

2026 Climate Considerations

!2026 weather patterns

Plan for these regional patterns this season. La Niña effects: cooler, wetter springs in northern regions. Irregular frost patterns: late spring freezes possible even in warm zones. Heat dome potential: early summer heat waves in the Southwest. Drought watch: Western states continue water conservation.

Adaptation Strategies

  • Row covers ready: Keep frost protection handy even after "safe" dates
  • Water systems: Drip irrigation and mulching more important than ever
  • Heat protection: Shade cloth for summer crops in hot regions
  • Flexible varieties: Choose heat and cold tolerant cultivars

Essential Tools for 2026 Success

  • Soil thermometer - Know when soil is ready
  • Row covers - Frost protection and pest barrier
  • Mulch - Temperature regulation and water conservation
  • Drip irrigation - Water efficiency for changing climate
  • Shade cloth - 30-50% for heat protection

Conclusion: Your Best Garden Starts with Perfect Timing

The 2026 growing season offers amazing potential for home gardeners. With proper timing, succession planting, and climate-appropriate variety selection, you can enjoy fresh vegetables from spring through fall (or year-round in zones 9-10).

Remember: it's better to plant a week late than a week early. Cold-stressed plants rarely recover fully, while patiently waiting for proper conditions sets you up for abundant harvests all season long.
