Sulphur is an important secondary nutrient for all plants. A vital component of many amino acids, it is essential for efficient protein production. A plant nutrient and soil acidifier, Yellow Sulphur helps to grow strong, healthy flowers, fruit, vines and vegetables. Yellow Sulphur: Helps prevent yellowing of leaves Reduces susceptibility to powdery mildew and black spot Can be used as a soil conditioner for acid-loving plants. Increased pollution control has led to decreased sulphur deposition, which means soils require extra sulphur to keep plants healthy. Sulphur deficiency shows as a yellowing between the veins and around the margins of the youngest leaves, and can decrease a plant’s resistance to a range of diseases. Yellow Sulphur can also be used to neutralise the effects of hard water when plants are grown in tubs or planters. Applied as a tonic or soil nutrient, Yellow Sulphur should not be used on red or white currant plants.
