Manutec Magnesium Sulphate (Epsom Salts) 1kg

Yellow leaves on an otherwise healthy plant are often a magnesium problem, not a watering one. The older leaves go pale between the veins while the plant keeps trying to grow.

Manutec Magnesium Sulphate, better known as Epsom salts, puts that magnesium straight back. It dissolves easily in water and works quickly once it hits the soil.

Mix around 10 grams, about two teaspoons, into a litre of water and pour it around the base of the plant. For a stubborn case, repeat every few weeks until the colour comes back. Citrus and tomatoes tend to respond well.

A kilo lasts a long time at those rates. Dilution rates and uses are in the tabs below.
