Evergreen Substral Rhodo-Vital

Substral® Soil Treatment Rhodo-Vital (1 kg) is a soil conditioner with added nutrients for rhododendrons, azaleas, and other ericaceous plants. It lowers the pH value, improves soil structure, and supports water, air, and nutrient balance – thus reducing yellow-brown leaf discoloration and stunted growth caused by unsuitable soil conditions, and allowing plants to sprout vigorously again.
