Prunus domestica subsp. insititia · Tree
Silver leaf: Prune out infected wood well below the infection site during dry weather and sterilize tools between cuts.
Bacterial canker: Prune out infected wood in dry weather during summer to avoid spreading bacteria via rain splash.
Brown rot: Remove all fallen fruit and mummified berries from the tree and ground to reduce overwintering spores.
Plum aphids: Encourage natural predators like ladybirds or use a strong jet of water to dislodge infestations.
Honey fungus: Improve drainage and avoid wounding roots; severe cases may require removing the tree to prevent spread.
