I had planted several Glad bulbs 2 years ago. The ones I planted in full sun turned brown, died and have not regrown. Some of the ones I planted in one bed in the partial shade grow about 2 feet tall then fall over, never bloomiming. I have one that I planted in another bed that has grown to almost 4 feet, only part of it has fallen over but still not blooming. I have bulb fertilizer in the ground around it, have tried a bloom fertilizer, still nothing. Please help. Any ideas will be GREATLY appreciated.
