Hymenocallis are tender perennials and must be kept away from frost. They require mild to warm conditions to sprout and are therefore best started off in a heated greenhouse or indoors in the spring.
— Plant into pots between March and May using multipurpose compost, and grow them on indoors or in a warm greenhouse. They can be grown indoors throughout the season or transplanted outside from May onwards. Alternatively, you can plant them straight outside in May.
— Plant the with the neck of the bulb exposed.
— Space the bulbs around 10-15cm apart from each other in borders or containers. They don’t need a lot of space, one bulb usually fits into a 6” pot where it will be happy through the season. You could fit three in a 12” pot.
— When planting outdoors, choose a sheltered position in full sun with free-draining soil..
— Water-in after planting and continue to water regularly when in growth. Allow the soil to become almost dry between watering. Don’t allow the bulbs to sit in wet soil whilst dormant.
