How Long to Refrigerate Hyacinth Bulbs Before Planting


Hyacinth plants produce long spikes of small, blooming flowers that come in a variety of colors. Violet, pink, white and salmon are just a few of the splashes of color you can add to your yard. Because these flowers grow from bulbs, you must plant them in the fall for spring blooms. Keep them in the refrigerator if your live in a warm climate. The bulbs should be forced into dormancy before they can bloom again.

Digging Up Your Hyacinths

Choose a time after your hyacinths have bloomed in the spring to dig them up for storage. Wet the planting area to make digging easier. Dig a few inches away from the base of the plant. Lift underneath the plant to not disturb its root system. Wash the bulbs off and dry off thoroughly. Inspect the bulbs for any fungal diseases or damage. Throw away any bulbs that feel mushy.

Storing Your Hyacinths

Place you hyacinth bulbs in an onion bag and store in the refrigerator. Because hyacinth bulbs are poisonous, you must take extreme caution when storing them. If you have children in the house, place them high enough in the refrigerator that it is beyond their reach. Make sure that you keep the bag labeled to indicate they should not be eaten. Refrain from keeping your bulbs in a drawer with vegetables or fruit. There are certain vegetables and fruit that can produce ethylene gas, and it will cause your hyacinths to prematurely bloom. You can also store your hyacinth in a pot full of moist potting mix. Check the pot every week to make sure that the soil is moist. Keep your hyacinth bulbs in the refrigerator for 12 to 14 weeks if you live in a southern region that does not have freezing temperatures. The freezing temperatures force the bulb into dormancy. The bulb can not bloom again without having at least six weeks of dormancy. If you live in a northern region, you can keep your bulbs in the refrigerator for six weeks before replanting in the fall. It's best to wait until your soil has had one frost before planting them.


Take your hyacinths out of the refrigerator when you are ready to plant. Till the designated planting area. Dig a hole 8-inches deep and place them in the hole with their pointed ends facing upward. Give them 6 inches of space. Cover them with soil and mulch over the area.
