Roses: Insect Treatment and Prevention

Roses: Insect Treatment and Prevention

Most common rose pests: aphids, then beetles. Both effectively treatable. Early, regular treatment recommended—don't wait until pests reside on the bush or in flowers.


Aphids and Other Sucking Insects

Very common. Attach to stems and leaf tops/bottoms. Suck plant juices, weakening it and inviting disease. Multiply quickly into unsightly masses if untreated—you won't want to cut flowers for indoors.

Aphids and most sucking insects are easily treated. Many insecticides work. Organic gardeners use insecticidal soaps. Wide range of insecticides and soaps available at garden stores or homemade.


Beetles

Second most common enemy. Japanese beetles are most common. They harbor in flowers and quickly destroy them. Once spotted, it's too late for that bloom.

Apply Malathion, Diazinon, or other insecticides at first sign and regularly.

For organic Japanese beetle control: garlic plants ward them off. Plant garlic as companion near bushes. Garlic sprays also deter.

Many other insects like roses. Most effectively treated with insecticides. "Systemic" insecticides absorb into plant system, protecting for weeks.
