Top 10 garden pests and diseases

Apr 2, 2021
The box tree caterpillar has come top of the list of gardeners' concerns. The Royal Horticultural Society (RHS) said it was the number one pest inquiry, as it continues to spread across the UK.
The alder leaf beetle, which feeds on the leaves of trees, entered the top 10 for only the second time. The beetle has recently become re-established in some parts of England.
Honey fungus was the top concern in terms of diseases, while other types of fungi took advantage of the warm wet weather to attack fruit trees.
The RHS has analysed thousands of gardener enquiries for its latest tally of top 10 diseases and pests. The charity is conducting research into controls for the box tree caterpillar, focusing on the use of nematodes.
