Prevent And Combat Rose Rust: 4 Natural Remedies

Rose rust is one of the most common fungal diseases that can affect your garden roses. Here you’ll learn four natural remedies for rose rust.

Recognizing rose rust: Characteristics and spread


You want to make your garden more colorful and you’re planting a large flower bed. Finally, the first rose bushes sprout and the flowers begin to bloom. However, the appearance is marred by brown spots on the leaves: it is rose rust.

Rose rust is a fungal disease and is one of the most widespread rose diseases in Europe. It is caused by the two fungal species “Phragmidium mucronatum” and “Phragmidium tuberculatum”. The fungi spread their spores via the wind and thus enter your garden. There, the spores multiply quickly and can infect your roses.

The course of the disease in rose rust is identical for both types of fungi. You can recognize the optical changes especially on the rose leaves: Yellow-red spots form on the upper side of the leaf. Small pustules are also visible under the leaf. These are usually yellowish-brown in color and form the spore deposit of the fungi. If these two symptoms are present, it is clearly rose rust.

In most cases it remains with the optical changes. Severe infestation occurs only rarely and can then lead to the loss of foliage of the plant. In this case, the rose shoots may also be affected and the spores may be transferred to the next flowers. Ultimately, severe rose rust can cause the rose to die.

Preventing rose rust: What you need to know

Prevent And Combat Rose Rust: 4 Natural Remedies

For the health of plants, prevention is better than cure. To prevent your roses from being affected by rose rust in the first place, you can prevent the disease. These tips can help prevent infestation of your roses:

  • Plant your roses with enough spacing between them. The fungus multiplies best in a humid and warm climate. If the plants are spaced enough apart, the wind can aerate them well. This keeps the rose petals dry.
  • Plant the rose bed in a sunny location. This way you can also make sure that moisture does not form between the leaves.
  • When watering, distribute the water only in the root area and not over the entire plant. This way the leaves will stay dry.
  • Don’t fertilize the plants all the time. Fertilizers often make them more susceptible to pests and diseases like rose rust. If you fertilize, use organic fertilizer.
  • Carefully remove individual infested leaves. They should not be left with the roses, as spores spread quickly. Instead, dispose of them in the compost or organic waste. This allows the fungal spores to be broken down by natural organisms.


Tip: There are special rose varieties with a seal of the “General European Rose Novelty Test”. These are particularly hardy and more resistant to diseases such as rose rust.
