astible keep dying
I have planted an astilbe in one place 3 different times and it keeps dying. The first one I planted I don't remember the variety but the 2nd and 3rd were both spinell. The spot gets some morning sun but is mostly shady the rest of the day. The 3rd time before planting my husband reworked some mulch into the soil hoping that would help. Our soil is mostly clay. But the plant just shrivels up and dries up. We water it and do everything we can think of. I thought astible were supposed to be an easy plant to grow. What is the problem? Is there a better tall shade plant I should grow there? I also tried a fern and it died.
