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.
Most of fruit grown in gardens can be attacked by sap sucking aphids (commonly known as greenfly, blackfly or plant lice) during spring and summer. These may reduce the plant's vigour and spread viruses.
Metallic blue fuchsia flea beetle adults and their black larvae can feed on the leaves of fuchsias, occasionally resulting in severe defoliation.
Fuchsia gall mite is was found for the first on the mainland of Britain in 2007. Since becoming established it has become a serious problem for fuchsia growers in southern England and is spreading northwards.
Fungus gnats, also known as sciarid flies, are associated with damp composts especially in house plants and seed trays.
Gall mites are tiny animals that cause distinctive abnormal growths (galls) on some plants. In most cases this does not affect the health of a plant.
The greyish green larvae of geranium sawfly larvae eat holes in geranium leaves during the spring and summer.
The caterpillar like larval stage of two species of sawfly can completely defoliate Geum in spring and summer.
Gladiolus thrips can cause a mottling on foliage and flowers of gladiolus.
Glasshouse leafhopper can cause a pale mottling on the foliage on a wide range of glasshouse and garden plants, including tomato and fuchsia.
