my force grown tulips are done blooming—can I now plant the bulbs outside this spring
same as above
The standard answer is to throw them out, especially if they were forced in water. The bulbs are too depleted to do well plus some tulips don't reliably repeat the next year. If you research this and determine yours is a perennial tulip (in your climate) and it has been in soil, then yes, you can put it out. You will have to acclimate the plant to the outdoors over a week once you see tulips up in your neighborhood. If you are like me and your tulips have been in water, you'll say "what the heck" and plant them anyway. They may not come back. C'est la vive.
