The Q&A Archives: Refrigerating Bulbs

Question: Can bulbs be refrigerated until planting? We are thinking about doing a Science project which will involve planting bulbs and using fertilizer. My question is, can We keep the bulbs in the freezer or refrigerator until we need them the last week of December? The project is due in Feburary. We are going to try to prove that when fertilizer is used the bigger the bloom. Any suggestions? Maybe it will show that the blooms last longer.

Answer: You can keep them until planting time in a cool dry place, but do not let them freeze because that is too cold. Remember that they need a chilling time after planting in order to grow normally -- the time varies depending on the type of bulbs and the temperature. You will eventually need to pot them up and chill them in their pots. A refrigerator will work for this, but do not store them in the same refrigerator with fruits such as apples -- the fruits give off a gas that causes the blooms to fail. A cold garage or cold frame may also work for this. Good luck with your experiments!
