|My tulip flowers are spent; when do I cut back the plant?
|You can cut back the flower and stem now, but wait until the foliage has naturally withered and died before removing it. The leaves manufacture energy for the bulb so it can produce a blossom next year. If you cut the foliage back too soon, you'll rob the bulb of this required nutrition. If the yellowing leaves are unsightly you can gather them together and tie them, then gently bend them down so they'll lay on the ground.
