Rose Pest Control

To manage rose pest control successfully, checking your roses frequently is crucial

To assume that garden pests will never infest your roses is wishful thinking. Roses provide natural habitat and food source for many insects. Most of them are harmless and cause little damage, others may destroy canes, blossoms or even the whole plant.

A balance between pests and beneficial insects would be a desirable situation for a garden. Aphids, for example, will be eaten by lady beetles, green lacewings and their larvae or even by chickadees.

Some pests are so well protected that they cannot sufficiently be hit by predators or pesticides. Among this are cane borers and thrips.

To achieve a natural balance in your garden you have to check your roses frequently, and you have to know what is going on in your garden.

Easy Steps To Rose Pest Control

A rose pest control program starts with planting a rose at the proper site. Location means everything to the health of a rose and if a rose is not healthy, she is prone to every sort of garden pests.

Choosing the right site, proper feeding and rose care maintenance are fundamental requirements for the health of your plants.


Having a balance between good and bad insects in your garden is preferable but sometimes pests can be annoying and should simply be avoided or removed from the plants. My approach to prevention is the use of:

  1. Neem oil (not neem extract): It is also effective against common rose diseases such as powdery mildew, black spot and rust. I use neem at least once a month starting before the growing season. Best time to apply neem is in the morning or the evening.
  2. Horticultural oils Can be used in two ways: When your roses are already infested, use them to smother pest insects and their eggs during the growing season. The second way is to use dormant oils, which is applied before roses go to sleep in late fall. Dormant oils kill overwintering pests as well as disease spores. Water the plants well before using horticultural oils and don’t use them during temperatures higher than 85°F.

Neem oil and dormant oils are permanently present in my garden pharmacy. As they are not chemical but botanical insecticides, they are short-lived and must be used more frequently to get adequate results.

Spraying Insecticidal Soaps

Insecticidal soaps kill soft-bodied pests such as whiteflies, aphids and spider mites. These oils are of organic origin and are nontoxic to humans. I use insecticidal soaps on infested plants as well as for prevention once a month. Apply the oil in the evening and not in the sun. Otherwise, the leaves could burn.

My preferred product: Rose Pharm Organic Insecticidal Soap

Spraying Pesticide Following A Routine Program

For those rose gardeners who don’t have the time to control their plants daily, chemical pesticide may be the best choice. I recommend spraying your roses following a routine program each year. (A single spray in mid-May, mid-June and early September)

Recommended Product: Bayer Garden Multirose Concentrate 2. It is a combined insecticide and systemic fungicide.

Spraying – Some Tips 

Spraying pesticides may not be everybody’s preferred pest and disease control method, and if you use chemical pesticides use them carefully.

Read the label first: Follow the instructions and protect your skin. Use a dust mask while spraying

Sprayer: Never use the spraying equipment with other fluids

Weather: Do not spray when it is hot, sunny or windy. Best time to spray is the evening, when bees stopped working.

Spraying: Apply the pesticides on top and the underside of the leaves until the liquid starts to run off the leaves

After Spraying: Carefully wash the equipment, hands, face and every part of your skin that got in touch with the pesticide.
