Bay leaf suckers

By Gardeners' World on 18/10/2011 14:33:48

insects - which have a fluffy white covering - carry on feeding on the sap, prolonging the problem. Prolific breeding in summer means the symptoms don't disappear. Young, winged, sap-feeding insects attack young bay foliage, discolouring and distorting it

Pea and bean weevils are a nuisance but rarely a major problem on the veg patch. The larvae live in the soil and feed on the root nodules. Then when the adults emerge in June and July, they climb up the plants and eat the edges of the leaves

to feed. After 2-3 weeks, the larvae pupate inside the leaves and emerge as adults. The damage is mostly cosmetic but where many leaves are affected, the plant may be weakened or die. Different species of leaf miner fly affect specific plants.A maze


Mildew on cucurbits

kill a plant. Since there are separate fungal species that affect different plants, an attack on your curcubits won't lead to a garden epidemic. Powdery mildew and powdery mildew on roses are similar problems, with similar solutions.The first sign


Ants

By Gardeners' World on 18/10/2011 11:13:01
