Q.My Astilbe Is Not Healthy
Hi. I bought a new Astilbe plant this year and planted in my front garden that faces east with morning sun. I live in Cochrane and we have a lot of clay in the soil. We added compost horse manure to our clay and when I planted the Astilbe, we added bone meal into the hole w water. The plant was doing really well until all of the rain that we had. Now the plants looks like it is partly surviving. It has brown leaves that are very dry. We added peat moss to the base of the plant hoping it helps it. Can you please help me save this plant? When it was blossoming, it was beautiful.

It could be overwatered from the rain and the clay soil, which doesn't drain well. Or, it could be the plant is getting too much sun. Usually, just about an hour of sun is enough. You might consider moving it to a shadier location with moist, rich soil.
