I have a red hydrangea which normally blooms well. This year however, it has not done at all well. At the moment, it has a whitish mildew on many of the leaves, also it seems to have spider web in many of the leaf clusters with myriad little white mites in the webs and the flowers are almost all decaying without having fully bloomed. Can you please advise on problem and any possible solution.

I'm having some problem in removing decorative bark from an area where I want to add about 10-20 cm top soil and sow a lawn from grass seeds. Can I just leave it and cover it with soil? The bark is Shamrock Decorative Bark Mini Chips.
