Direct Sowing Outdoors

Planting seeds directly in the garden where they will grow to maturity.

What is Direct Sowing?

Direct sowing means planting seeds directly in the garden or final growing location where they will mature. This is the simplest and most natural way to grow many plants, and is preferred for species that do not transplant well.

Which Seeds to Direct Sow

  • Root crops: Carrots, radishes, beets, turnips (do not transplant well)
  • Large seeds: Beans, peas, corn, squash
  • Fast growers: Lettuce, spinach, arugula
  • Hardy annuals: Cosmos, sunflowers, nasturtium
  • Trees and shrubs: Many species prefer direct sowing

When to Direct Sow

Crop TypeSoil TemperatureTiming
Cool-season crops40-60┬░F (4-15┬░C)2-4 weeks before last frost
Warm-season crops60-85┬░F (15-29┬░C)After last frost
Fall cropsCooling temps6-8 weeks before first fall frost

Soil Preparation

  1. Clear the area: Remove weeds, rocks, and debris
  2. Loosen soil: Work to 8-12 inches deep with fork or tiller
  3. Add amendments: Mix in compost or aged manure
  4. Rake smooth: Create a fine, level seedbed
  5. Moisten: Water deeply a day before sowing

Planting Methods

Row Sowing

  • Make furrows at recommended depth with stick or hoe
  • Sow seeds at recommended spacing
  • Cover with soil and firm gently
  • Water with fine spray

Broadcast Sowing

  • Mix small seeds with sand for even distribution
  • Scatter over prepared bed
  • Rake lightly to cover
  • Roll or press to ensure seed-to-soil contact

Hill Sowing

  • Create small mounds of soil 12-18 inches apart
  • Plant 4-6 seeds per hill
  • Thin to strongest 2-3 seedlings
  • Common for squash, melons, cucumbers

After Sowing

  • Water gently: Use fine spray to avoid washing away seeds
  • Mulch: Apply 1-2 inches of organic mulch to retain moisture
  • Mark rows: Use stakes or labels to remember locations
  • Keep moist: Water regularly until germination
  • Thin seedlings: Remove extras to recommended spacing
