Q.Can forced indoor tulip bulbs be planted outdoors?
Late last fall (closer to winter), I purchased many tulip bulbs on clearance sale. I have never forced tulip bulbs to grow indoors in vases and I question whether or not the bulbs will be successful growing outdoors after being forced indoors.

They do not come back well after forcing. They are meant to be thrown out after flowering, as they use up almost every bit of energy they have to flower instead of to produce leaves to harvest energy. This makes them very drained out and unable to come back from the stress.
