Before planting, at night, the seeds of garlic must be soaked in a weak solution of potassium permanganate.
- Garlic grows best in loose, well-drained soil that’s been amended with organic matter. Seed garlic requires a cold period for healthy growth.
- Separate the cloves just prior to planting and locate a sunny area to grow them in. Plant the cloves with the point facing upward about 2 to 3 inches (5-8 cm) deep and spacing about 6 inches (15 cm).
- Apply a generous amount of mulch to help protect their shallow roots over winter. This can be removed in early spring once the new growth is ready to emerge and the threat of freezing has ceased.
- During its growing season, garlic requires frequent watering and occasional fertilizing. The plants can be harvested in late summer.
