Vegetables & Sustainable
Overcrowded plants cannot grow rapidly or reach a good size. Thin small root crops, salad crops, and those grown for greens early at the second or third true-leaf stage. Thin root crops, such as beets or carrots, so the plants are 2 inches (5 cm) apart in the row. Thin radishes so plants are 1 inch (2.5 cm) apart and head lettuce to 12 inches (30 cm) apart. Vegetable Gardening at a Glance: How to Plant and Store lists standard spacing for each crop. However, different spacings may be required in your garden.
