These can handle plenty of water so you don't have to worry about root rot. They also react well to very heavy pruning so shape it how you like and tip prune as the branches grow to make it bushier. I would put down a heavy layer of mulch as well and just keep it off the trunk. You can make it like a foot deep. Unless you want to drench it weekly with insecticide I would just bag the fruits if you find maggots in the fruit.
