The joy of raspberries in the garden is quickly spoiled when the bushes become ill and bear little fruit. So you can see what your raspberries are suffering from and how you can fight the diseases.

The most common diseases of raspberries

  • Red root rot
  • tail disease
  • fruit rot
  • focal spot disease

Symptoms of Red Root Rot

If your raspberry is only developing weak buds, you should take a look at the roots. If these are discolored brownish to gray, it is root rot.

It is mainly caused by waterlogging. The rainwater or irrigation water cannot drain off properly. As a result, fungi develop which attack the roots and later also the rods.

When planting, make sure that the soil is very loose. Since the fungal spores are distributed in the garden, moving the plants is of little help. Cut off affected rods and discard.

The rod disease

This is also a fungal disease. It mainly attacks perennial shoots. The fungus attacks the rods so that they are no longer supplied with nutrients. They die and need to be removed.

As a preventive measure, choose a bright location. Thin out the bushes regularly, because too many rods encourage the spread of the fungus. Regularly remove weeds from under the bushes.

Autumn raspberries are rarely affected by the disease. Since the canes are cut back immediately after harvest, no perennial shoots remain on the bush.

fruit rot

You can recognize this fungal disease by the fact that the fruits on the bush begin to go moldy. The damage begins as early as flowering.

Collect and discard any affected fruit. Spraying with plant broth made from field horsetail can help. Often the only option left is to apply chemical fungicides.

focal spot disease

If small, purple spots form on the young rods, it may be focal spot disease. Although this disease is common, it usually does not affect crop yield. Simply cut off infected rods.

tips and tricks

When planting new raspberries, look for fungus and disease resistant varieties. There are now some breeds on the market that are much more robust and cope better with pathogens.
