1. Do I fertilise Citrus Gems Citrus?
Citrus Gems are Australian Native trees and generally have much less fertiliser requirement than usual citrus ( which are greedy .
Use a low phosphourous, native fertiliser or if you wish to use a citrus fertiliser use it at 1/2 the recommended dose.
Organic tonics are also excellent as a top up.
Citrus Gems are best feed before flowering and fruit set, - late winter or early spring.
They have shallow fiberous root systems so we also advise providing them with a luscious layer of organic well rotted compost and leaf litter, not too close to the trunk and out to the drip line.
