Guidelines for storing flower bulbs
This temperature storage chart has been drawn up for dry sales! Modified
preparation temperatures can be
necessary for purposes of flower production in order to time the flowering
periods
General remarks:
- Storage temperatures apply to properly dried, clean products
- For the forcing sector and for different planting and flowering periods, modified temperature treatments may be necessary
- It may be important to ask the supplier about previously applied storage temperatures
- A decreasing series of temperatures means that the highest temperature
should be applied at the beginning of the
storage period and that the lower temperatures should be applied towards planting time - For spring-flowering bulbs, we assume a storage period lasting to planting
time (no later than mid-December and, in
any case, before freezing winter temperatures set in - If we mention protecting from desiccation, it would be advisable to use a filling material, and this should be added to the packaging in any case
- "Dry and ventilated" means to use ventilated packaging
- Pay special attention to aphid control
