Sprekelia (or Jacobean Lily) corms are tender, and must be protected from frost. They should be grown in frost-free conditions in the spring and will require winter storage.
— Plant your Sprekelia bulbs between March and May and grow on in warm, frost-free conditions to plant out after risk of frost has passed in your area. Alternatively, you can plant them directly outside in early May, although they will be behind those started off earlier in the season.
— Grow in borders or containers in a sunny, sheltered spot, in a fertile but well-drained soil. If planting in containers, we recommend using a peat-free multipurpose compost.
— Plant shallowly, with neck of the corm exposed.
— Space the corms about 10-15cm apart from each other.
— Water-in after planting and keep hydrated while in growth, not allowing the soil to fully dry out or become waterlogged at any point. Whilst the bulbs are still dormant, allow the soil to become almost dry before watering again.
— Sprekelia are perennial, but may not flower every year. Apply a liquid fertiliser after flowering to replenish the corms.
— To overwinter the corms, lift them before temperatures drop in the autumn and allow to dry off in a warm place for a few days, before trimming off any remaining foliage. Then store in a cool, dark, but frost-free place before replanting the following spring. Alternatively, you can leave the container in a cool but frost-free place and cease watering while the corms are dormant.
