I have noticed my only holly has suddenly began dropping its leaves. Is this OK during this hot spell? It is a young tree about 4 ft.

This indicates that it might not be getting enough water. Water the ground long and deeply 1-2 times a week rather than quick and shallowly everyday. Deep watering will make sure the water stays in the ground rather than evaporating from the top few inches.
