pampas grass flowers

Question

I have some pampas grass growing in the garden. The flowers were cut and brought indoors last year, and there are no flowers growing again this year. Can I do anything to make flowers grow again in this plant?

Answer 1

It is very early in the year for these to be flowering. This will happen much later, usually. If you don't see anything by the start of summer, then you can add potassium and phosphorus to the soil. This will help initiate flowering. Only do this if it does not flower, as this can affect the pH of the soil.
