Why overwinter flower bulbs?
Many flower bulbs originate from warm climates and do not cope well with the cold temperatures of a winter in temperate climates. By overwintering them properly, you protect them from frost and freezing bulbs, which greatly increases their chances of survival and flowering power in the following growing season.
Which flower bulbs should overwinter?
Not all flower bulbs need to be dug up and stored indoors for the winter. It is important to know which ones are hardy and which ones need extra protection. Here are some examples:
Hardy flower bulbs: Tulips, daffodils, crocuses and hyacinths are hardy and can usually remain in the ground.
Non-hardy flower bulbs: Dahlias, gladioli, begonias and cannas are examples of non-hardy flower bulbs that should be dug up and stored indoors.
Overwintering flower bulbs: step-by-step
1. Digging up the bulbs
Digging up the bulbs is the first step in the overwintering process. Do this after the foliage of the plants has died, usually after the first light frost. Use a garden fork to carefully lift the bulbs out of the ground, being careful not to damage the bulbs.
2. Cleaning the bulbs
Remove any excess soil from the bulbs, but be careful not to damage the bulbs themselves. Then let the bulbs dry in a cool, dry place for a few days. This will help remove excess moisture and prevent mold from forming during storage.
3. Inspect and sort
Check for signs of damage, disease or mold. Remove and discard any damaged or infected to prevent these problems from spreading to healthy ones.
4. Prepare for storage
For storage it is important to keep the bulbs in a cool, dry and dark environment. An ideal storage temperature is between 4 and 10 degrees Celsius. Place the bulbs in paper bags, net bags or open crates to ensure sufficient air circulation.
5. Storage medium
To prevent mold, you can cover the bulbs with a dry storage medium such as sawdust, vermiculite or dry peat. This will help keep the humidity low and protect the bulbs from drying out.
6. Check regularly
Check stored regularly during the winter for signs of rot or mold. Remove affected plants immediately to prevent the problem from spreading to others.
