Why Are The New Blooms On My Scabiosa Turning Brown?

Question

I live in high elevation in Calif.

Answer 1

This may have a lot to do with moist soils. They do need to dry out between waterings, and only need extra during dry periods and drought. Otherwise, rainfall is usually enough.

I would recommend a fungicide and watering only when the soil gets dry down further than 4 to 6 inches. It is also worth noting that it is a must to keep the soil a little on the acidic side.
