🌱 How to Plant Lettuce Seeds Successfully

1. Timing

Plant in early spring or late summer for fall harvest.

2. Soil Preparation

Use loose, rich soil with good drainage and consistent moisture.

3. Planting Depth

Sow seeds ⅛ inch deep—lettuce needs light to germinate.

4. Watering

Keep soil evenly moist. Dry soil causes bitterness.

5. Spacing

• Loose leaf: 6–8 inches apart

• Romaine: 10–12 inches

• Butterhead: 8–10 inches

6. Successive Planting

Plant new seeds every 2 weeks for a nonstop supply.

Aphids, slugs, and leaf miners can be controlled with row covers or organic sprays.
