Garlic Chives Garlic chives produces flat leaves with a light garlic flavour, use as chives. Sow and grow indoors for all year round crops. Sow 0.5cm deep, in small pots of compost. Water well and place in a warm position. A temperature of 15-20°C is ideal. Seedlings usually appear in 14-21 days. Grow on in cooler, but not cold conditions. For earlier outdoor crops, sow indoors from March to May. Gradually accustom plants to outside conditions, before planting out into warm, well-drained soil, 20cm apart, during May to June. Alternatively, plants can be grown on a light windowsill. Or sow outdoors from March to May for ease, where they are to crop, 0.5cm deep, directly into finely-prepared, warm, well-drained soil, which has already been watered. Thin seedlings to 20cm apart. Harvest by cutting leaves once they reach 15cm tall. Pick a few leaves from each plant so they regrow quickly.
