Sulphate of Potash

Yates Product of the Month for February 2008 is Sulphate of Potash (also called Potassium Sulphate)
a rich source of potassium, the major plant nutrient that encourages flowering and fruiting and also
improves disease resistance in plants.

Late summer is one of the worst times of year for fungal problems (many diseases flourish when the
weather's warm and humid) so this is a particularly good reason for giving plants a treat with Sulphate
of Potash at this time of year.

Yates Sulphate of Potash comes in a 750g pack. It can be applied in two ways: either by sprinkling dry
powder over the garden bed (then watering in well), or by mixing into the soil before planting. Apply as
closely as possible to plants so that the nutrient liquid will move into their root systems.

Sulphate of Potash is often recommended as an additive to Blood and Bone. This popular organic
fertiliser contains nitrogen and phosphorus, but is notoriously deficient in the third major plant nutrient,
potassium. As a result, if Blood and Bone is used to feed hungry plants like vegetables, it's important
that the crops are also supplied with some added potassium. Yates Sulphate of Potash is a convenient
way to do just that.

Roses particularly appreciate regular applications of Sulphate of Potash. This encourages rose growth
and flower production and, most importantly, improves the ability of rose plants to stand up to common
diseases such as black spot and powdery mildew. Sulphate of Potash is like an extra shot of vitamins
that boosts the rose at the time of year when a bit of extra help can be most beneficial.

For larger gardens, Yates Gro-Plus Sulphate of Potash is available in an economical 4kg pack size.
