The Rose Garden’s Ten Most Wanted List
The following insects have made it to the Rose Garden’s Ten Most Wanted list. Read carefully so you can identify them and eradicate them from your garden.
1. Aphids
Aphids top this list because they are the most frequent rose pest. They love to nestle into the buds and shoots of rose bushes. While low to moderate levels of aphids will not do much harm to your roses, you need to keep an eye on how they spread. High numbers of aphids will produce a lot of honeydew. This substance encourages mold growth and will eventually cause your rose leaves to blacken. You may notice that your flowers shrink in size and the buds may even be killed. Lady beetles and syrphid flies are the natural enemies to aphids and will keep the population under control. You can also spray the plant with water or insecticidal soap. Aphids are usually a problem during spring and early summer. Unless you have a really heavy infestation, it is uncommon to have to use insecticides against them.
2. Spider Mites
If you notice your rose leaves are stippled or dried up and dropping to the ground, you may be infested with spider mites. These little insects are so tiny you may need a magnifying glass to see them. They like dry, dusty conditions. You can control spider mites by providing a little more water to your roses to cut down on dust. (more…)
