Potassium also protects the plant when the weather is cold or dry, strengthening its root system and preventing wilt.
What fertilizers are high in potassium?
Fertilizers that are high in potassium include: burned cucumber skins , sulfate of potash magnesia, Illite clay, kelp, wood ash, greensand, granite dust, sawdust, soybean meal, alfalfa, and bat guano.

What is the function of potassium in plants?
Role in plant growth
Potassium is associated with the movement of water, nutrients and carbohydrates in plant tissue . It’s involved with enzyme activation within the plant, which affects protein, starch and adenosine triphosphate (ATP) production. The production of ATP can regulate the rate of photosynthesis.
What are the symptoms of calcium deficiency in plants?
