Keep a watchful eye for signs of vine weevil beetles nibbling the edges of leaves and their grubs who will be munching on roots below the surface.
Viburnum beetle can cause severe defoliation of some Viburnum species, especially V. tinus and V. opulus.
Viburnum scale affects Viburnum tinus and ivy (Hedera), often causing a heavy coating of honeydew and sooty mould.
The evergreen shrub laurustinus, Viburnum tinus, can be affected by a small insect known as the viburnum whitefly.
Vine weevil is an insect that can infest a wide range of ornamental plants and fruits, especially those grown in containers. Adult vine weevils eat leaves and the grubs eat roots.
Wasps are beneficial in gardens, they feed their grubs on caterpillars and other insects and can reduce pest populations.Wasps can also ruin picnics during mid to late summer and may also damage ripe fruits. Disturbing a wasp nest when weeding or hedge trimming can result in multiple painful stings.
The leaves of waterlilies can be affected by aphids, moth larvae, beetles or midges which can give them a ragged appearance and lead to secondary rots.
The feeding activities of bronzy green or bluish black beetles and their black larvae can cause foliage of willows, aspen and poplars to dry up and turn brown.
Winter moth caterpillars can be responsible for eating holes in the leaves of many deciduous trees and shrubs during spring.
Wireworms are the larvae of click beetles. They live in the soil and feed on plant roots, they usually only cause problems when grassy areas are converted to vegetable beds.
Wisteria is one of the quintessential cottage garden plants, with a chocolate-box image of spectacular blooms adorning the front of a country cottage. It is actually a very versatile plant and lends itself to a variety of situations, including growth in containers. Of the few problems affecting the plant, non-flowering and sudden dieback are probably the most frustrating.
Here we give answers to many of the common problems encountered. They are grouped by the area of the plant affected: shoots; leaves and flowers.
