Here is the top swale which is mostly macadamia nut trees, but mixed in is a cherry bush, a tropical apple tree and the davidson plum in the foreground. Then of course green manure on the ground as well as sweet potato and pumpkin. There is still too much grass and other weeds for my liking but I'm sure someone will tell me they have uses I'm as yet unaware of, so its all OK.
I think this Davidson Plum is possibly the happiest tree on the property. I've mulched it heavily but otherwise its had no different treatment.
