Hippeastrums are bulbous plants. Their flowers which are usually produced in Spring are trumpet-shaped with prominent stamens and may be white, red, orange or yellow.
Water 2-3 times a week, more during hot weather and during flowering. Let the top half mixture to dry out between waterings. Do not water while resting.
Apply standard liquid fertilizer once every 2 weeks from the time the flowers have finished blooming until mid Summer. Then change to high potash fertilizer to help mature the bulb and ensure a flowering stalk the next year. Stop feedings entirely after mid Autumn.
Hippeastrums dislike root disturbance. Re-pot every 3-4 years when bulb outgrows its pot.
Detach offsets when they are one or one and half inch across, keeping as much root as possible attached to them. This is best done at the time of re-potting. Plant in 3 inch pots and treat as mature bulbs. These plants may also be raised from seed, a process involving a 3-5 year wait for flowers. Seedlings are not given a rest period but are kept growing through without a break.
They need bright light with some direct sunlight throughout the active growth period. Too little light results in elongated leaves and in no flowers the following year.
Cut off the stalk once the bloom have gone.
Prepare bulbs for the resting period by removing all the dried foliage. Leave them in their pots of mixture and store in a thoroughly dry place at a temperature of 10°C.
Too much heat will shorten the life of the flowers. Temperature not higher than 18°C is advisable for Hippeastrums at flowering time.
If room is dry, spray lightly over buds but never spray flowers or leaves. Do not spray while resting.
Well drained soil.
Watering is necessary when transplanting, but be careful not to over water.
