Thawing of lily bulbs

Thawing of lily bulbs

Defrosting, lack of oxygen and dehydration.

Incorrect defrosting of the bulbs from the storage cells can have a major impact on the quality of the lilies in the greenhouse.

Plan the arrival date of the bulbs at such a time that they can thaw quietly and still be planted on time. Before planting, allow frozen bulbs to thaw gently in the shed or in the climat cell and ensure sufficient oxygen. Separate the crates on the pallets so that the crates can defrost evenly. To prevent lack of oxygen during and after defrosting, it is advisable to open the bags, especially if the lilies are defrosted at temperatures higher than 10˚C.

Defrost at a temperature around 10˚C and count on a defrosting time of at least four days. Once the bulbs have thawed, they can be planted. If you are unable to plant due to circumstances, store the bulbs at 2˚C. When the bulbs are thawed, breathing (oxygen-uptake) increases. Especially if the bulbs are stored at higher temperatures. If the bulbs are stored in closed bags, the oxygen percentage in the box will quickly fall, which can lead to a loss of quality.

The sprout starts sprouting from thawed bulbs. The longer the sprout when planting, the shorter the migration time in the greenhouse. Ensure that the sprouts do not become too long due to breakage.

Prevent any form of drying of bulbs and roots when planting. Do not scatter more bulbs at once than the planters can plant within half an hour.
