What is eating the leaves of my cumquats?
I thought it was possums! But one cumquat now defoliated and two more on the way. The leaf looks as though it has been eaten by a caterpillar but underneath there is a brown / silver trail that I think is the problem. NOthing on stalks / stems. Will the defoliated tree revive? What to do to others under attack?
hard to say from this decription. The silvering could be caused by citrus leaf miner (see section on our website) and can be pruned of and avoided with the use of regular PestOil spraying. It also causes distortion of new leaves but does not cause defoliation, this is usually from dryness or malnutrition. If it is a caterpillar you will see droppings but no silvering. Snails cause silver trails but don't usually eat citrus leaves. If its possums, Yates has a wonderful new product available - Yates Possum Repellent Spray helps protect your precious plants by deterring possums from browsing on sprayed plants.

Problem really needs to be seen to be properly identified, suggest take sample to your local nursery and talk to horticulturist to confirm. Doesn't sound like possums.
