How To Force Bulbs Indoors

Year Round Colour

Winter and the garden is sleeping under a thick blanket of snow, keeping warm until Spring arrives and calls the bulbs that brighten our Springtime gardens and ease our snow worn eyes.

You do not have to wait until Spring to enjoy your favourite bulbs; thee is no need to wait for those splashes of colour to break the monotony of the winter yard. You can grow you favorites indoors all Winter long.

The way you achieve this indoor bloom is by using a method that is called forcing and it is not as painful as it sounds. Your indoor garden will work best when you select bulbs that are hardy, this way you will be able to have colour throughout the seasons,

The following are the hardy bulbs that are most commonly forced:

- crocuses (Crocus species),

- daffodils (Narcissus species),

- hyacinths (Hyacinthus species)

- tulips (Tulipa species).

You can also force:

- Dutch iris (I. x hollandica)

- netted iris (Iris reticulata),

- snowdrop (Galanthus species)

- grape hyacinth (Muscari species),\

- winter aconite (Eranthis species)

- star-of-Bethlehem (Ornithogalum species),

- and Brodiaea species.

There are some bulbs that are difficult to force and may require special conditions such as artificial lighting, among these are the Allium, Camassia, Lilium and Scilla species.

There are four stages involved when forcing bulbs:

(1) selecting appropriate bulbs;

(2) planting;

(3) cooling;

(4) Forcing into flower.

You will achieve the best results when you but the cultivars that are recommended for forcing. ; This is important when you are working with daffodils, hyacinths and tulips, where the cultivar selection is wide.

The bulbs need to be handled with care so avoid exposing them to temperature extremes for example.

If you are not going to plant them immediately then be sure store them in a cool place (35 to 55 °F). You can place bare bulbs in the refrigerator for several weeks before you pot them.

It is best to keep them in a paper or mesh bag than have holes for breathing. If you are going to use the crisper drawer in your fridge make sure that you do not put fruit or vegetables in the same drawer. The ripening process gives off a gas that may harm the bulbs.

Remember that some bulbs are poisonous, and should not be eaten so if you have young children it may be best not to use the fridge for bulb storage.

I suggest repotting them in larger containers until you can plant them out.

Bob they are about 3 ins up now and I still have them in the dark......what do you think I should do? Are you sujesting I bring them upstairs now and keep them inside for a few weeks more in containers? and if so when do you think I should put them outdoors(while still in new containers? or from the inside strait into the garden)

thanks so much!

I'd keep them in the dark for another week, then transplant them into containers, keeping them inside until aroound May 25 or so, dependning upon the last frost date in your area. Then you can move them outside to the garden.

My dad will be finished his chemo treatments end of march. I bought bulbs, planning to plant them in the late fall. I wanted to surprise him with the beautiful flowers at the end of his treatment(blue passion bend tulipa and crocus). The ground was to hard to plant the bulbs in November as he lives in the great white north (Niagara, LoL). Now what do I do? The bulbs have been sitting in my Moms fridge, it is now March 8. Some of the bulbs are sprouting others are soft and seem to be moldy. Id like to plant them, they look like a gorgeous mix of beautiful flowers. I'm new to gardening, but I love gardening. Any advise would be appreciated. Thank you :) Happy gardening

I would pot up the bulbs that are sprouting and place them in a sunny window for now. Be sure to water them.

Andrea  5 years ago

Thank you. I will give it a whirl....... WEEEEEEE!!!!!!

I hope they end up looking half as beautiful as they look on the bag.

After they bloom in a pot, when can I place them in the ground.

You have nothing to lose by cutting them back, they ,may have sat in the dark too long.
