Black vine weevil causes damage to numerous plants such as rhododendrons, cherry laurels and new trees by their typical habit of chewing small notches on the edges of leaves and needles. But it is the grubs that cause the most damage by feeding on the roots of plants and a heavy infestation can result in the damaged plant dying.
Many plants in the ornamental garden suffer from biting and sucking insects. A second generation of the rose leaf hopper can now appear, causing white leaf spots on the leaves. In August, plant-damaging bugs appear on many ornamental plants. Their sucking activity not only causes leaves to weaken and curl but can also affect the flowers of many ornamental plants too. BugFree Bug and Larvae Killer+ is an effective means of tackling these pests.

To help boxwood regenerate after cutting back, treat with a homoeopathic plant elixir that strengthens the plant before winter.
