Successional Sowing
Sow a short row every 2–3 weeks for a continuous supply. Lettuces hate heat — in midsummer, sow heat-resistant varieties in a shaded spot or use a cold frame.Cut-and-Come-Again
Sow salad leaf mixes thickly and cut with scissors 2–3cm above the ground when 10cm tall. They regrow for 3–4 cuts. This is the most space-efficient way to grow salad.Bolting
Once a lettuce "bolts" (runs to seed), the leaves turn bitter. Choose bolt-resistant varieties for summer, and harvest hearts promptly.Soil: Moist, fertile, moisture-retentive soil. Will tolerate partial shade in summer
