Clematis Pests and Control Methods

Clematis Pests: Aphids

Both black and green aphids will attack clematis. Spring to early summer is the peak season for aphids, so special attention should be paid. Aphids usually gather at the top of young shoots, on stems or on the back of leaves, eating the leaves and flesh of the plants. A large amount of insect feces will contaminate the plants.

After the clematis enters the growing season in spring, you should always observe whether there are aphids on the leaves. If the situation is serious, you can spray some insecticide. Note that if the bottom of the plant is too dry, it will cause aphids to gather, so the surrounding environment should be kept moist to reduce the occurrence of aphids.

Clematis Pests: Caterpillars

Most caterpillars emerge in early spring and prefer to be active at night, feeding on new leaves and flower buds. Properly increasing the light at night can reduce the gathering of caterpillars, or spraying pesticides can kill pests.

Clematis Pests: Leaf Miner

The larvae of leaf miners often shuttle between leaves, forming one or more irregular gray-white curves on the leaves, forming spots at the ends. Leaf miners will not have a significant impact on the growth of the plant, but will only reduce the ornamental value of the leaves.

In the early stages of leaf miner infestation, the affected leaves can be cut off and thrown away. Note that the spots at the end of the curve of the leaf surface contain the larvae of the leaf miner. Be sure to cut off the spots completely and destroy them. If the infected area of ​​the plant is large, remove the leaves and spray the plant with appropriate amount of pesticide.

Clematis Pests: Snails

Snails are mollusks that prefer warm and humid environments. They reproduce in large numbers in spring and devour tender leaves and buds, causing serious damage to plants. But they are afraid of light and heat. They hide in humid, shaded areas during the day and come out to look for food at night. Wherever it crawls, it will leave glowing mucus, which not only affects the growth of the plant but also looks unsightly.

Spraying 70 to 100 times the concentration of ammonia water at night can kill pests on a large area and also achieve the purpose of fertilization. Alternatively, choose diatomaceous earth and charcoal ash and bury it at the roots or spray it with water.
