How to grow
Cultivation
Garlic grows best in a sunny, sheltered spot with fertile, well-drained soil. If you have heavy soil try growing your garlic in a raised bed or container. To produce good quality bulbs garlic needs a period of cold, so it’s best planted in late autumn or early winter. Divide each bulb into individual cloves and space the cloves 15cm apart, with the tip 2.5cm below the soil surface. Space rows 30cm apart. Harvest from early summer once the leaves have turned yellow. Please see our grow your own advice page about garlic for further advice.
Propagation
Propagate by dividing the bulb into cloves
