Q.My two amaryllis bulbs came in boxes with soil and grew long leaves with no flower stalk or flower ever appeared. Any idea why?
I watered and put in warm room and followed directions for 3 months. No pictures but you can imagine perhaps.

It's always possible the bulb was deficient before it was purchased. Once home, overwatering or lack of light could have prevented blooming. Since it has leaves, continue to feed and water according to the instructions below. You can move it outside after the threat of frost has passed. You can try to force it again in the fall or leave it planted in the ground outside in a protected area on the south side of the house. You are in zone 7 so it should be OK if mulched well in the fall. Garden amaryllis bloom in the spring.
