Dwarf Hemlock in container? Or other suggestions...
I have a spot with a concrete structure (looks like a small well) that is part of a drainage (not sewage) system. You can see it in the picture. I have been trying to think of something evergreen and deer resistant to grow approximately where the tall grass/weeds/rocks are and cover the concrete thing. I would love a dwarf prostrate evergreen but am concerned about the roots getting into the pipes. I'm assuming the roots would invade? Also, not sure what could thrive in the heavy wet clay that is there.
Sooo, am wondering about planting a 'Cole's Prostrate' hemlock in a container, then digging the container into the ground a bit and letting it grow over the structure.
Does this seem like a reasonable way to grow a dwarf hemlock?
How long can you keep an evergreen like this in a container? Will it's growth be limited by being in a container? How large a container would I need?
Are there other evergreens that come to mind that might suit this predicament?
I would love for it to one day become a large mounding green cover.
Thanks in advance!
