Potassium is one of the three macronutrients that are essential for healthy plant growth (Nitrogen and Potassium are the other two). Used in chlorophyll formation, it plays an important part in strengthening plant cells and facilitates the movement of water throughout the plant. Regular applications of Potash give a strengthening effect on your plants which helps prevent damage and disease, and improves the quality of flowers, fruit and seeds.
Potash can be applied directly to the soil in powder form, or mixed with water to make a soil and foliar spray.
Blood & Bone can be applied at the same time for a total plant feed.
