Why are the leaves on my katsura tree (Cercidiphyllum japonicum pendulum) curling in towards the central rib?

Question

Can someone please give me some advice about this problem as i had to fight for this tree at a local nursery as its a lovely example and had more than one admirer the day i bought it.I got it in spring and the leaves had just come out but were slightly damaged by hailstones, or so i was told?!. I repoted straight away as it was only in an 8" pot and was 3 meters tall, it responded by puting out lots off new growth but gradually starting with the old leaves first they have started to curl. Please help

Answer 1

Possibly red spider mites. Have a look on the underside of the leafs with a hand lens.

Answer 2

You dont have the required nutrients in the soil. Leaf curling on any plant is heat or nutrition.

The leaves will not curl due to insects - never seen it.

Curling leaves means is responding to something comming internally from the sap of the plant/tree.

Dont water - let it dry out ,and move it in the shade for a week or two and see how it responds - still curled - repot with different soil.
