I planted some huge astilbe roots last fall and am looking forward to them flowering this year.
The directions said to cover the top of the roots with about an inch of soil, but some creature (squirrels? voles? cats?) LOVES to dig around that bed. The soil has been uncovered and no matter how much I recover them, the tops are exposed again the next day.
Is this going to cause harm to the plants? Should I bury them with several inches of soil and put some chicken wire type of covering to discourage digging, or is it better to let the tops expose a little bit?
