What does Potassium (K) do?

Potassium (K) is a critical element of nearly every aspect of plant life (one of the big three fertilizer nutrients, NPK). To name a few of its functions, it facilitates movement of water and nutrients through the plant, it strengthens stems and roots, and it improves stress tolerance, including heat, drought, foot traffic and disease. Potassium also plays a key role in flower, fruit, and seed development, and is critical for overall plant health.
