Q.Curling Leaves New Zealand Holly
The leaves on my holly are curling inwards. (2.5 ft high) I have it in avery large pot in a sunny position. As it is in large round stone pot ( 2ft hight and 30inches at widest point ).It does have new growth re leaves and the stems feel springy, not dry or brittle. There are no brown spots on the leaves nor are they yellow, nor can I see insects. There are a couple of black leaves. The shrub just looks limp, my first considerations was that I had not watered it enough. The bark is doing what is should do i.e. peeling I have recently put pebbles around its base to provide some protection from the sun and also to help prevent weeds popping up. I live about 4 miles from the seaside in on normal side road which is not busy I water the plant regularly ( until water runs out of the bottom of the pot ) and do feed with Tomato feed

Curling leaves can be due to insects, disease, or environmental issues. I'm wondering if your plant is getting too much water. The container may be too large and is holding too much moisture. Let it dry out completely before watering again.
