That makes sense to me amd it is essentially the same reason I don't grow trees or shrubs. I have to replant every year.
It does take a little of the permanent out of permaculture, but it is really a lifestyle. Trees and scrubs are also tougher and require more thinking as you can't move them year after year.
That said, grow a variety of cabbages. Fast, easy to grow and harvest, nutritious, lots of meal choices.
