1. Pre-Forcing Storage Hadeco®
Hippeastrum may be stored until the end of January under ideal conditions:
Temperature: 9°C (48°F) is ideal
Humidity: 70% to 75% is ideal
If mould forms: React as soon as the first mould forms (usually on fine roots). This symptom indicates that there is insufficient air movement and/ or the air is too humid.
The best medium is one that is relatively dense but well- draining:
Avoid peat such as the image shown.
Use a combination of sand and soil.

4. Location for Growing
A greenhouse in which the above requirements can be maintained is ideal but Hadeco® Hippeastrum may be forced in full light as well as in darkness until the stem is 10cm in length provided the above guidelines as to temperature, ventilation and humidity are followed. If the bulbs have been forced in the dark until marketing stage, the plants will need 4 to 7 days in medium light intensity to form chlorophyll. Rotate pots through 180° (a half turn) every few days if the light source is oblique from one side.
The following conditions will encourage shorter stems:
