Rose Diseases

Healthy Roses by Prophylaxis 


Prevention is better than cure-this saying applies especially to rose diseases. Therefore, no compromises when choosing the right location for your roses:

Only at sunny and aerated places the foliage of the roses will quickly dry and makes it difficult for fungus to occur.

Good Care Prevents Rose Diseases

After prophylaxis, good care for roses is most important to prevent diseases. Watch out for the following:

  • Consistent soil moisture, loose soil and balanced fertilization
  • Cut withered blossoms, wild shoots and damaged plant-parts regularly
  • Dispose sick plant-parts and rose-cut into the garbage-can 
  • 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.

Only when diseases occur to a greater extent, you should hark back to plant protection products. Use eco friendly products to preserve bees and useful animals.
