Why have the leaves on my lily turned brown?

This sounds very much like lily disease which is a common fungal disease, especially virulent in wet seasons. The spores are spread in the air, by rain and water splashing on the leaves. This disease is often checked by the onset of warm, dry weather conditions.

Small red-brown circular or elliptical spots often with a yellow halo appear on the leaves, flower stems and buds. The leaves soon turn brown or bleached and wither, they hang down but remain attached to the stem. The flower buds are either killed or produce distorted flowers.

Any infected leaves should be removed and destroyed as soon as they are seen. In the autumn destroy any infected plant debris. Provided the disease has been checked and the bulbs have not been weakened or started to rot they can be saved for replanting.
