Prevention is Better than Cure Rose Diseases

This saying applies especially to rose diseases. Make sure your roses do well from the start, and you've already done a lot for their health.

  • Avoid overhead watering; keep the leaves dry

Hygiene is essential to keep the flowers healthy. Ensure the roses get as little as possible in contact with germs and pests. The following methods are helpful:

  • Cut withered blossoms, wild shoots and damaged plant parts regularly and dispose of everything
  • Dispose of infected plant parts and rose-cut into the garbage can; don't compost them!
  • Before applying winter protection, tidy up the rose bushes; remove foliage, hips and withered blooms and dispose of it
  • Cultivate useful animals

 

What to do in Urgent Matters

Check your roses for infestation with diseases and pests every time when it comes to regular rose-care. Usually it is enough to cut the effected plant-parts and dispose them into the garbage-can.
