I had two stargazer Lily bulbs, one in a pot the other in the ground.
The one in the ground was rotted with a single stalk trying to grow but it literally pulled right out from the center of the bulb leaving a hole. The rest of the bulb was rotten and mushy in the middle.
The one in the pot was all roots and no bulbs! Last year it was a huge, healthy bulb.
The one in the pot had poor drainage so perhaps that could of caused it. But in the ground was good drainage so it makes no sense.
Last year both plants were big and had multiple blooms. I did fertilize very often all year, perhaps I over fertilized and the plants were absorbing the bulb for leaf nutrients and the winter did them in with little or no scales left?
When in the season do you fertilize Lilys and stop?
