Prepare your growing medium for planting. If you’re direct sowing seeds, add a 2- to 3-inch layer of fresh compost to the top of the planting area. If you’re starting cabbage seeds indoors, fill your seed trays to the top with pre-moistened seed starting mix.
Use a dibber or a chopstick to make shallow holes in the soil or in the center of each seed starting cell. Cabbage seeds only need to be planted ¼” deep, which is not very deep at all. If you’re direct sowing, space your seeds about 12 inches.
Water the planting area gently and keep seeds moist until they germinate (which usually takes 7 to 12 days). If you’re starting seeds indoors, use a water bottle to gently spray water on the soil surface and water your seed tray from the bottom to avoid displacing seeds.
