Q.Amaryllis bulbs that never bloom
I have Amaryllis bulbs that never bloom. They get a lot of foliage, but no flowers. I have several bulbs in one planter. A friend gave me several bulbs about 10 years ago because she could not get them to bloom and the ones I had were always beautiful year after year. I planted hers along with mine and they still have never bloomed.

Here is a great link with step by step directions.
How wonderful that your caring for these bulbs.
