After cleaning up 6 sacks of elephant grass yesterday (it's probably not called that, but it's a weed that takes over the lawn and grows 4 ft tall) I tidied the kitchen garden this morning. The kitchen garden is where I grow my ginger, garlic, tomatoes and chile peppers. I reckon I need some more soil and better fertilizer, but the ginger is growing beautifully. I managed to fumigate this afternoon, since it poured for about 30 minutes this morning.
Edit: I've just discovered it's called guinea grass. None the wiser, but it's a real nuisance!
