Before I would ripe out something that takes a licking by your husband and keeps on ticken' I would give it a try.
A good example of taking a bush and turning it into a
tree is the loquat. Everywhere you see them they look like
trees. However, if left alone they are just one nice big bush. (See photo below!) This one is mine too~~!
BTW that ground cover you see is
growing so fast I have to dig out around it ever couple of days or so to remove the "grass." In 6 weeks there will be no grass at this rate~~! Which is good! The ground cover is a purple
potato vine.
