Q. My Astilbes did not bloom this summer. Plants are wilting and look pitiful. Any suggestions?

I am including images of a couple of my plants. They all look similar.

Astilbe is a shade plant. If yours is getting afternoon sun, it may be leaf scorch that you see. Astilbe chinensis tolerates sun and dry spells better than Astilbe arendsii. However, even the A. chinensis varieties need consistently moist soil if they are in sun. If your plants are new, they may not be to blooming size yet; your plants look small but they might be a dwarf variety. Blooming takes a lot out of a plant and one that is under heat, nutrient deficiency, drought or other environmental stress may forgo blooming.

They may have just completed their natural cycle, but there could be other reasons. https://www.gardeningknowhow.com/ornamental/flowers/astilbe/growing-astilbe-plants.htm
