Growth promotion of roses through the use of Trichoderma

The quality of cut flowers is largely determined by the number of stems, the length of stems and the size of flower heads.

In this experiment we used our Trichoderma strain to test its influence on roses. For this we worked together with a farm in Kenya that grows roses in greenhouses. Over a period of 2 months, the soil (1x per month) and the foliage (2x per month) were treated several times. 3 months after the start of the trial, the harvest took place and the cut roses were sent to our laboratory in St. Gallen for evaluation. 537 roses were examined and it was found that on average the flower head was 5 mm larger. The feedback from the producer was also that the number of stems per plant and the length of the stems had increased significantly.
