People buy expensive fertilizers for the good growth of plants, but sometimes a simple thing present in the house can work as an excellent fertilizer. Wood ash is one such natural thing, which most people throw away considering it as garbage. Potassium, calcium and many essential minerals are found in it, which help in improving the health of plants. However, it is very important to use it in the right quantity and in the right way, because excess ash can disturb the balance of the soil.

Why is wood ash beneficial for plants?

Nutrients like potassium, calcium, magnesium and phosphorus are present in wood ash. It helps in increasing soil fertility, strengthening plant roots and improving the quality of flowers and fruits. It is considered a natural nutrient source especially for flowering plants, vegetables and fruit plants.

How to use wood ash properly in the garden?

The ashes should be completely cool and clean. Sprinkle it in light amount on the soil at a short distance from the stem of the plant and then mix it in the soil. After this, do light irrigation so that the nutrients reach the soil properly. Do not use it more than once a month.

In which plants wood ash should not be used?

Plants that prefer acidic soil, such as azaleas, blueberries, camellias and rhododendrons, should not be treated with wood ash. Ash increases the pH of the soil, which can stunt the growth of such plants.
