How to Prevent Black Spot Disease

Black Spot Disease is one of the most common rose diseases. Whether a gardener is growing climbing roses, rose bushes, or taking care of miniature roses, their roses are susceptible to this disease. Black Spot is caused by a fungus, and appears as small black spots on the upper surfaces of leaves. Rose plants can be vulnerable to this disease if rain or other moisture remains on their leaves, or if they are exposed to either another diseased plant or parts of a diseased plant.

This disease is hazardous to a plantís health as infected leaves often fall off early, leaving the rose bush with fewer resources to generate energy through the autumn. Any infected leaves or stems which do not fall off and are not cut off during the winter will carry the Black Spot Disease, which can then be spread to other leaves in the spring.

There are many ways Black Spot Disease can be prevented.

  1. Be careful to buy disease free plants. Examine rose plants while at the garden supply store, and before bringing them home. When planting, plant them the recommended distance apart, to make sure there is enough air circulation between full grown plants. Get gardening advice from anyone who offers it, as others who live in the same area will know a lot about rose bush care specific to that area.

  2. . There are many disease resistant variations of the different types of roses. Even for the gardener who is growing roses from a cutting from a neighbor, it is worth it to check if the rose is a resistant variation. Resistant does not mean immune, but a resistant plant has a lower risk of getting a disease.

  3. Water bushes at soil level. Watering rose plants from above allows leaves to trap moisture, which allow fungi to propagate. Also, make sure the soil is draining properly, so moisture doesnít get trapped in the roots. This is important when taking care of roses, but also when taking care of any plant.

  4. Rose care can be a very delicate business. Be careful when transplanting rose bushes, as injured plants are more vulnerable to disease.

  5. Some gardeners choose to apply fungicides to their plants. There are a variety of fungicides available, some more eco friendly than others. These can prevent disease, especially if applied consistently and starting before the rainy season, which is when there is the most risk. When spraying, spray both the upper and lower surfaces of leaves.

  6. Keep on eye on leaves. Many gardeners, concerned about the flowers, donít always look at the leaves. But the sooner a disease is detected, the less damage it will cause. If a rose becomes infected, cut away the diseased areas and send the clipping to the landfill. Putting the diseased leaves and stems into the compost will allow the fungus to spread to whatever plant the compost is put on next year.

Black Spot disease can weaken or kill rose bushes, and so an important part of taking care of rose shrubs or bushes is to prevent diseases from damaging your quiet backyard garden. Itís easy to get gardening advice from experts on how they prevent diseases as well, and all this information combined will allow you to happily enjoy your healthy rose plants.
