Purple Fountain Grass In Containers

Question

Is there a specific type of fertilizer that is suitable for these plants and, is it necessary to fertilize them. When the flowers (or plumes) turn brown during the summer or fall, is it necessary to remove them?

Answer 1

In your area, and since you are growing in container, your care routine will be a little different than typical. Since you will be dividing and repotting each Spring, it won't usually be necessary to use fertilizers. You will refresh the soil in Spring as it is being divided and planted back.

As far as pruning goes- Sure! You can do this before bringing them back in for the Winter.
