I have removed 40 holly plants from my North facing yard. The ground was covered with what I know as 'volcanic rock'. The porous black rocks that are light. Hope you understand what I mean.
I have an established tree that does not lose it's leaves in the winter. Sorry I cannot tell you what it is, but it would provide shade for the maples in Summer.
I would like to plant several Japanese Maples (Crimson Queen, Orangeola, Shin Deshojo) beneath that large tree and wonder if the 'volcanic rock' will pose a problem if I don't remove all of it? Would it be wise to dig a deeper hole and put some of that 'volcanic rocks' in the bottom of the hole, to provide more drainage? I would appreciate any suggestions as I'm new to planting those beautiful trees here in Texas.
I would appreciate any suggestions.
