Potassium is involved in many plant processes, but extra potassium is not needed
in the soil of most home or market gardeners who are using compost and mulch.
Same goes for magnesium – it’s an important mineral, but most of us have enough
of it already.
That said, someone of us do need it. For example, my soil is a rare one that has
plenty of calcium, but needs a little magnesium and potassium.
The first fertilizer below supplies both, so if you’re short on both potassium and
magnesium, it’s a great choice.

The importance of potassium to plants
Potassium has two roles in the functioning of plant cells. First, it has an
irreplaceable part to play in the activation of enzymes which are fundamental to
metabolic processes, especially the production of proteins and sugars. Only small
amounts of potassium are required for this biochemical function. Second,
potassium is the “plant-preferred” ion for maintaining the water content and hence
the turgor (rigidity) of each cell, a biophysical role. A large concentration of
potassium in the cell sap (i.e. the liquid inside the cell) creates conditions that
cause water to move into the cell (osmosis) through the porous cell wall (Box1).
Turgid cells maintain the leaf’s vigour so that photosynthesis proceeds efficiently
