Preventing rose pests and disease

There are many ways to protect your roses from pests and disease, both synthetic and organic. These methods assure a healthy and beautiful plant growth. You might want to start off by cleaning the area around the roses of any fallen leaves or debris and then pruning the plant.

Use a magnifying glass to see any signs of pests like aphids, rose chafers, leafhoppers, thrips, mites, slugs, sawflies and Japanese beetles.

The Japanese beetles have hard shells and can be noticed because of their bright color. You can either get rid of them by hand or drown them. If you wish to use a chemical insecticide to get rid of them, use one that doesn’t harm the roses.

Aphids deal internal damage to the roses by sucking on the rose juice and damaging rose buds that haven’t bloomed yet. Aphids are either brown, red or green. Use a hose to get rid of them temporarily or a insecticide that is harmless for the rose.

If spider mites are an issue for your roses, the leaves of the plant will lose their color and drop off. You can use a hose to get rid of them, but for a more permanent solve, get some beneficial insects that eat spider mites. If you plan on using an insecticide, make sure it is harmless for the rose.

Waxy-shelled insects can affect the healthy growth of a rose. You can either use lacewings to kill them off, as lacewings are waxy-shelled insects’ natural predator, or use a rose-friendly insecticide.

Rust affecting roses is a common issue. Orange patches on the leafs are sure signs of disease. This can be solved by removing the damaged and spotted leaves and pruning the plant, or by applying a rose-friendly pesticide made of lime sulfur.

Black spots can appear on any part of the plant. If infected, the part will eventually fall off. It must either be removed or sprayed with neem or copper sulfate fungicide.

The primary symptom of rose mildew is a white powder like coating on the plant leaves. Those leaves must either be cut off or sprayed with neem and watered weekly with a hose.

It is best to avoid these issues through simple measures like applying a layer of mulch around the plant and tamping down weeds. Get rid of any pests or diseases before they spread too much.
