Galtonia bulbs are half hardy and can tolerate temperatures down to -5C. They can be planted directly outside in mild areas, but it is safest to start them off in a sheltered location such as a cool greenhouse or under cover in the garden.
— In mild areas, plant your Galtonia bulbs straight outside between late March and May, in a fertile but well drained soil. Alternatively, start them off in pots in a cool greenhouse and transplant into the garden later in the season.
— Choose a position in borders or containers in a sheltered spot with full sun. If planting in containers, we recommend using peat-free multipurpose compost.
— Plant with the tip of the bulb facing upwards, sitting just below the soil surface.
— The bulbs can be spaced around 40-50cm apart, or between 25-40cm apart for a denser display.
— Water-in after planting and keep hydrated while in growth – it is important not to let the soil dry out at any point.
— If you live in a mild area and have well-drained soil that does not become waterlogged in the winter, they can be left in the ground throughout the year with a thick mulch to protect them from winter frosts.
