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.
This fungal disease of walnut trees is unsightly, and in wet summers can cause significant early leaf fall. Unfortunately, it can also affect the fruit of the tree, rendering the walnuts useless.
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.
Many households have water-softening units fitted to reduce household limescale on appliances and to reduce the quantity of household detergents used. Advice can be confusing on whether softened water is safe for plant use.
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.
Lawns can become waterlogged if water sits on the surface and drains slowly. Waterlogging is more likely to be a problem on compacted and clay soils. However, it is worth noting that patches of dead grass where the soil proves very difficult to re-wet can be caused by a fungal problem: dry patch.
The development of brown leaves or dieback of shoots on a much valued specimen can be alarming, but does not necessarily mean you will lose the plant. More often than not, brown leaves, dieback, wilting and leaf drop are caused by weather damage; such as drought, waterlogging, snow, frost or hail.
