I love this mint plant. It has grown like crazy. However, it is very
invasive and is shooting roots into neighboring plants and sprouting
everywhere and all around.
I learnt that it should be contained by planting in space with no-out. I am
thinking of planting it in an old Fish tank and bury the fish tank into the
ground. I inherited this fish tank (1.5 ft deep X 4 ft wide X 2 ft high)
when we
moved into this old house. Has anyone done this? What are the problems if I
do this?
