Hi, we have a dwarf orange and dwarf mandarins trees that are 18 months old ( in ground).

The new growth on both have curled up distorted leaves. Trees have not flowered. Could you please help identify problem. Have used white oil and have fertilised with small amount of urea.

Hi Rob,

Thank you for contacting Yates.

Looks like the tree is affected by a pest called Citrus Leaf Miner. A tiny nocturnal moth lays its eggs on leaves, a tiny caterpillar hatches, tunnels through the leaf distorting it as it goes to the edge, rolls it over and pupates there. 
It is active all through the warmer months and you can control it by trimming off the affected leaves and spraying Yates Nature's Way Citrus & Ornamental Spray every 7-14 days. Click here for more info:


Hope this helps and happy gardening :)
