After identifying garden pests and diseases, sometimes spraying will be necessary but more often beneficial insects are the better solution
From time to time pests and diseases will make rose gardening life really hard. I primarily try to get rid of the pests with organic remedies but occasionally the use of pesticides will be a better choice to keep the plants out of troubles.
Nevertheless, pesticides should always be treated with respect.
As not only pests populate our plants, but also beneficial bugs it is important to identify the insects first. Here you can find information about common garden pests and how to treat them.
I know it is annoying to find pests on your nourished and fostered roses but in many cases the insects are harmless or even beneficial. That’s why it is important to know the dwellers on your rose bushes.
The lovely and familiar ladybug is one of the most useful insects in the garden.
The specialty of ladybugs and their larvae are to eat soft-bodied insects, especially aphids.
A ladybug can eat about 50 aphids a day.
Green lacewings are known as aphid lions. A soon as the larvae hatch from the eggs, they develop a big appetite for aphids, soft-bodied insects, mites, thrips, whiteflies and small caterpillars as well as their eggs.
The larvae are green-grey colored and look like small alligators.
As adults they feed on nectar, honeydew and pollen, some species still feed on the pests.
These small arachnids feed on plant eating thrips, spider mites and many pest eggs.
Tiny and harmless (to people) wasps that feed on eggs of moths and caterpillars
They look similar to house flies, but they are important enemies to Japanese beetles, caterpillars, sawflies and many other pests.
Parasitic nematodes kill many pest insects in the soil but have no effect to beneficial insects like lady beetles or earthworms. They kill garden pests in the ground before they become adults.
To reduce garden pests and avoid using pesticides it is a good idea to encourage beneficial insects to come to your garden.
Beneficial insects need places to hide and reproduce. A variety of garden plants like yarrow, dill or fennel will attract them as well as offer excellent possibilities to reproduce and hide.
Sometimes if too less beneficial insects populate your garden it is possible to buy them online.
Spraying with a broad-spectrum pesticide means to kill good and bad insects in the garden together. Use a pesticide that targets especially rose pests.
As I already said, most garden insects are harmless to roses, and many of them are beneficial. Unfortunately, there are some insects that eat and damage your roses.
Many of them are easy to spot, such as Japanese beetles or aphids. Others, like most caterpillars, will hide during daytime. You can find them with a flashlight in the evening or nighttime, when they feed on the roses.
Other insect pests such as thrips or spider mites are very hard to identify and sometimes it is hard to get rid of them too.
