Cypress aphids are a sap-sucking insect and one of the causes of dieback on conifer hedges. Active from May to November, these insects are common throughout southern England, having become increasingly problematic on conifer hedges since the 1980s.
The conifer species most affected by this pest are the Leyland cypress, particularly ‘Castlewellan Gold’, as well as Lawson cypress and some Thuja.
- Rapid yellowing of shoots in the summer; by late summer they will be brown in the affected parts
- The effects of the dieback on the hedges is more obvious on the clipped hedges, with the lower parts often more severely affected than the top
- A black sooty-like mould may develop on the stems and foliage
Whilst damaged hedges can recover it is generally a slow process. A hedge that is cared for and pruned during the growing season will be more resistant to Cypress aphid damage. If you are experiencing issues with these pests, contact Naturally Trees for a free, no-obligation quote to keep your hedges regularly trimmed.
Pesticide control can be useful, dependent on how large or dense the hedges are. We recommend spraying in the early summer to prevent damage occurring.
