Leaf spot disease on the hydrangea

Leaf spot disease: the symptoms

The leaf spot fungi cause visible changes in the leaves of the hydrangea.

• Foliage turns yellow
• Leaves are covered by spots of different sizes
• these are colored dark
• all spots have a brown center

The disease progresses in such a way that the leaf tissue initially thins or tears as it continues to grow. Eventually the affected leaves fall off completely.

Fight infection with scissors

A frequently recommended measure for fungal infections on plants in private gardens is to cut away the infected parts of the plant. In the case of a hydrangea with leaf spots, it is even the only measure if you do not want to resort to chemicals. Home remedies unfortunately do not have a great effect.

• promptly remove all infected parts
• do not add to the compost, the fungus can survive for a long time
• Dispose of plant cuttings as residual waste
• Disinfect cutting tool

Keep the soil free of fungi

Leaves that have already fallen should not be overlooked during the rescue operation. they are carrier of living fungal spores, which can lead to a new infection in neighboring plants at any time. the Leaf spot disease is also used frequently, for example Cucumber and Camellias observed.

Heavy infestation

If your hydrangea suffers from severe leaf blotch infestation, you must remove it from the garden immediately so that other plants are not infected. If you don't want to give up the hydrangea, you might have to resort to a fungicide quickly.

Prevent leaf spot disease

Leaf spot disease usually occurs when the plant suffers from a lack of nutrients and at the same time there is high humidity. A large part of the preventive measures can be derived from this:

• fertilize better and as needed
• thin out regularly so that leaves dry well
• Avoid too dense planting
• water only through the roots
• Pay attention to disinfected tools when cutting
