Mature trees in the gardens could be under real threat from very destructive bark-eating beetles and weevils. You can identify the possible damage with small dead branches spread intermittently throughout the canopy of cypress trees.

The female beetle or weevil lays eggs under the bark of small cypress tree branches. Larvae are small, cream-coloured grubs that feed on the soft material beneath the outer bark. Get the tree ready for its natural defence with surrounding with grub -resins.

If you are growing cherry or pear slug and if these plants are in their juvenile stage black slug is the most dangerous. It looks like a flat, black slug but matures into a small black fly, technically known as a sawfly. Sawflies graze on the surface of cherry, pear and other ornamental leaves.

You can control the Sawfly larvae by spraying the foliage with spinosad . This is a relatively new non-toxic bacterium that is specific to caterpillars and similar insects.

Leaf-eating caterpillar, known as light brown apple moth (LBAM) becomes a real problem causing serious damages in the shady gardens, rose beds and in vegetable patch. You must spray where they are grazing with non-toxic spinosad .

Citrus leaf minor normally attacks soft and succulent foliage. It becomes great risk if the trees are overstimulated with water and in particular, nitrogen fertiliser. Damage can be reduced significantly by not over- stimulating the trees during summer. It is better to control the citrus leaf minor by spraying with garden pest oil.
