Heavier plants of higher quality and less losses when growing Erica darleyensis in containers with DCM VIVISOL®

DCM VIVISOL® soil improver creates an active, rich and varied soil life and improves the biological conditions in the substrate. In such an environment, plant roots develop better and plants grow easier and bushier. In a trial carried out with Erica darleyensis, this resulted in stronger pot plants of higher quality and less losses.

Trial: DCM VIVISOL® MINIGRAN® applied to container-grown Erica darleyensis

In a trial with potted Erica darleyensis, the soil improver DCM VIVISOL® MINIGRAN® was added to the substrate. The plants showed better root development and their fresh weight was higher. Loss rate was lower and the plants were of better quality. For the grower, this resulted in more plants of A-quality.
