Epsom Salts have a very high magnesium content. This nutrient is vital to the healthy growth and development of all plants. Epsom Salts provides a solution to leaf yellowing caused by lack of magnesium and sulfur, especially in vulnerable plants such as tomatoes.
Use as a granular feed or dissolve in water and apply to foliage. Suitable for feeding a variety of vegetables such as tomatoes, broccoli, cauliflower and cabbage, plus trees, shrubs and flowers.
 
Tip: One handful of Epsom Salts is about 35g (1¼ oz).
