Spring flowering Wisteria are starting to clothe the walls with festoons of flowers.
It may be an excuse for newspapers to show pictures of Wisteria in full bloom but they are running a story about Asian insects wiping out our Wisterias.
- RHS entomologists are reputed to be very concerned about Wisteria scale insects that are 10mm in diameter.
- These insects deposit 1000’s of eggs to later feed on the plant’s sap.
- Branches and whole plants will succumb over time.
- Infections are worse around London and the south.
- Stems can become heavily encrusted with scales.
- Experts fear the bug may spread to other trees and fruit bushes.
- Treat with a systemic insecticide – it is no time to worry about organic insecticides.
- It also gives me a chance to show a white flowering Wisteria
