Apple Tree pests

[Emma08]

Hi
ive had my apple tree since last year, ive noticed some little flys underneath the leaves. the leaves are a little discoloured and a curling over, ive only just started gardening and wonder if anyone has any tips for me something i can do as i dont want to put any chemicals onto my tree.

If you don't want to put any chemicals on to the leaves you could just try a homemade soapy spray. Also clear up any fallen leaves and destroy to prevent the bugs from overwintering under the plant.
