If mummified fruit is left on branches after the leaves have fallen it could indicate an attack of brown rot fungus, which can lead to blossom wilt if left to overwinter. Use secateurs to prune out branches that carry such fruit to reduce the risk of further fungal attack. Also, keep an eye out for cork growth and flattened ends to branches, which may signify fungal canker on apples and pears. Remove diseased fruit and prune out infected wood, then sterilise tools with white spirit before pruning another plant.
Any fruits showing signs of brown rot should be removed
