I am a new amature gardener and have a Kilmarnock Willow in my garden in a large pot. On the whole, the plant is healthy but I have recently noticed some leaves curling and turning brown and others seem to have strange green lumps on them. Cany anone advise me as to what is happening and how to remedy the situation? Please see the attached photos.

Many thanks
Theresa

Hi, Theresa,
Those strange green lumps are galls - not uncommon on Kilmarnock willow. They are caused by pest, most likely sawfly, laying eggs in the leaf. The larvae grow in the little mound or gall within the leaf. The majority of the time, they do no real harm to the plant other than make it look unsightly. To help control the pest, you can remove the leaves with galls. Sprays don't tend to work by the time you see the galls since the larvae are protected within the leaf.

Many thanks! I will set about removing these leaves - once the weather permits.
