The soil improver DCM VIVISOL® ensures an active, rich and varied soil life and improves biological conditions in the potting soil or substrate. DCM VIVISOL® improves the physical and biological fertility of the soil. It releases phosphorus from the soil and makes it available to the plant roots. In such an environment, roots develop better and deeper, making it easier for small fruits – in this particular case potted blackberries - to grow. This results in stronger, more vigorous plants with a more developed root systems. DCM VIVISOL® has a significant effect on root growth and nutrient absorption and strengthens the resilience of potted plants.
