Roses - Insect Treatment and Prevention
The most common insect pest of rose bushes are aphids, followed closely by
beetles. Fortunately, you can effectively treat and guard against both of
these pests. Early and regular treatment is recommended. Don't wait until
pests have taken up residence on the rose bush, or in the flower.
Aphids and other sucking insects are a very common problem. They attach
themselves to the stem and the top and bottom of leaves. They suck in the
juices from the plant, weakening it and leaving it open to disease. They
quickly multiply into an unsightly mass if untreated, and you will not want
to cut the flower and bring it indoors.
Aphids and most other sucking insects are easily treated. There are also
a variety of insecticides that will effectively eliminate this problem. Organic
gardeners use insecticidal soaps. A wide range of insecticides and insecticidal
soaps can be purchased at a garden store or made at home.
Beetles are the second most common enemy of your rose bush. Japanese
beetles are the most common. They like to harbor in the flower and can quickly
destroy it. Once you have spotted them, it is too late for that particular
bloom.
Apply Malathion, Diazinon or other insecticides at the first sign of these
pests and on a regular basis.
For organic control of Japanese Beetles, garlic plants are believed to ward
them off. Plant Garlic as a companion plant near the bushes. Garlic sprays
will also deter them.
Plenty of other insects like your rose bushes as much as you do. Most of
them are effectively treated with insecticides. There are "systematic"
insecticides that the plant absorbs into it's system, and will provide effective
protection for several weeks.
