We have 9 fruit trees that are about 6mths old, plum, peach, apricot, nectarine, oranges & mandarins. They appear to be growing healthy however apart from a thick layer of mulch & of course watering when the weather is dry, we haven't done anything to the soil or trees.
I'm just wondering if anyone has any suggestions on what we should do to keep them growing strong? should I spray them with anything to protect them from pests or fertilize etc? We are in SA.
Cheers
