Calla lilly – lots of green, no flowers.

Question

My calla lilies are in pots. They look very healthy and are growing, but no flowers- I have more than one bulb in the pot – is that the problem?

Answer 1

The problem is, likely, the fertilizer or type of soil that you are using! This sounds like an excess of nitrogen, or a lack of phosphorus and potassium.

A soil test will confirm this. Here is an article that will help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-soil.htm

You can usually fix the issue by adding phosphorus and potassium. "Bloom boosters" are a good source of these elements. Just start at 1/4 strength to make sure that you plants can handle it.
