Growing amaryllis in water

Question

I am growing amaryllis with roots in rocks and water and bulb above water..it is doing fine but water stinks as soon as it is changed almost. Any ideas to keep water smelling better?

Answer 1

I would recommend using a floral preservative in the water. This will prevent the bacteria from forming.
You can also make your own preservative:

2 teaspoons sugar
1/2 teaspoon chlorine bleach
1/4 teaspoon Alum
mix this with 1 quart of clean water.

Water should be changed every 3 days through the life of the bloom.
