How To Get Rid Of Black Spots On The Leaves Of Your Roses

Black spots on the leaves of your roses are one of the most common diseases of roses and it is the nightmare of many skillful gardeners. Black spots occur in roses especially during the spring and summer transition, but also throughout the summer, just when you want your roses to be more beautiful than ever. Fortunately, there are some ways you can prevent and treat this disease.
How do black spots appear in roses?

Roses are predisposed to a lot of diseases, so it is important to know how to distinguish between diseases to take the appropriate treatment. The black spots on the leaves are caused by the Diplocarpon rosae fungus, which attacks all the organs of the rose, from leaves and shrimp to floral buds. As a result of this disease, the attacked leaves get small dark-colored spots, which then get a brownish shade and only then become black.

Leaves affected by black spots fall sooner than they should, and the rose produces fewer flowers. The black spots on leaves of roses occur especially in rainy evenings and rains, in plants that do not have well-fed soil.
How to prevent and treat the black spots on the leaves of your roses

First of all, to be sure that your roses do not acquire the black spots on the leaves, it is good to plant resistant varieties. From these, you can choose the varieties Emeraude d’Or (Teahibrid), New Dawn or Danse du Feu (up flowing roses), Camp fire, Lavender Dream, Swany.

Secondly, to prevent and treat the black patch of the leaves to the rose, you must gather and destroy the attacked leaves at the end of the vegetation period. It is not advisable to use the diseased leaves in the compost and not to leave them in the garden, whether you cut them because they can spread the disease.

Another preventive measure is the proper cutting of roses and their planting at some distance from each other. Cuttings have the role of allowing the plant to breathe better and thus lower the risk of illness.

As for the distance between roses, this is essential as it prevents the spread of the black spots on leaves from one rose to another.

When you wet the roses, try to pour water directly at the root, without wetting the leaves. Water may favor certain diseases.

Another method to combat the black spots on leaves of your roses is the use of fungicides, such as Synthane 12 E or Mirage 45 EC.
