There is not much you can do about pillar rust. The fungal spores overwinter in pines. To prevent red currant disease, all of the pine trees in the area would have to be felled.

Prevention is better than cure

So that the red currant does not get sick in the first place, ensure a good location. The soil should not be too wet or too dry.

Cut the red currant twice a year, once immediately after the harvest and a second time in autumn.

When doing this, light the bush well. This makes it harder for pathogens to spread.

Pests are also responsible for diseases

There are a number of pests that appear on red currants. You should therefore examine the bushes at regular intervals. This is an effective way of preventing severe infestation.


Diseased plant parts such as leaves, fruit mummies or cut shoots must never be disposed of on the compost. As a result, the diseases spread to other, healthy plants. Throw the plant residues in the household garbage can or burn them, if this is allowed in your area.
