Rose Bush Care Problems
With every rose garden there are the possibilities of having problems. One of the most common problems with every rose garden is bugs. With the proper rose bush care you can prevent or even eliminate all your bug problems. There are various products on the market that help with these problems. For the organic grower, there are organic products to help your garden as well.
If you are having any problems with aphids, growing chives and garlic in the same garden will help with rose bush care. Aphids are small, almost colorless, soft-bodied insects that feed only on plants. You can put a clove of garlic into the soil before planting/transplanting; the rose will take up the exudation and become less attractive to the greenfly. There are also a wide range of enemies (predators) that can eliminate the aphid problem. Some natural enemies include lady beetle adults and larvae, lacewigs, syrphid fly larvae, and parasitic wasps. All are important to aphid control and rose bush care. If chemical control may be what you’re looking for, than it is best to use an insecticidal soap.
Japanese beetles feed on the foliage of many plants including roses. Japanese beetle larvae are a type of white grub that feeds on the roots causing twice as much injury to the plant than the beetles themselves. Japanese beetles are not everywhere, but wherever they are is a serious problem for gardens. These beetles can be prevented from damaging your rose garden by applying neem oil. Using Milky Spore targets the white grubs in the soil. This product may take several years to prevent and fully eliminate all of the white grubs.
Spider mites are another common rose bush care problem amongst rose gardeners. Spider mites feed on the plant leaves by injecting their toxin in to the leaf, then they drink back the juice. By them doing this, it leaves a small yellow dot on the leaf. Leaves can quickly turn yellow if hundreds or thousand of these bugs are feeding on your roses. Some natural predators include Phytoseiulus persimilis, California occidentalis, Lady bugs and Chrysoperla species. These are all excellent predators to use for any spidermite infestation you may have.
The Green Lacewing, known as Chrysoperla (kry-SOPE-er-lah) species, is also widely known as the spider mite destroyer and perfect for rose bush care. Green lacewings do not fly away like Lady bugs, and will feed for 3 weeks as larvae before changing to adulthood. These are aggressive predators and they feed on Aphids, caterpillars, loopers, Mealybugs, Scale crawlers, Spider mites, Thrips, Whitefly, and many others.
Phytoseiulus persimilis is a predatory mite that feeds on a number of different spider mites. This predator will eat the eggs, nymphs, and adults. These mites will usually eat about 5 spider mites a day or eat about 20 mite eggs a day. If used correctly, the Phytoseiulus persimilis should gain control in about 4 weeks. These predatory mites are the most effective in temperatures up in the 80s with mild humid conditions.
