Will plants die if too much wood ash is used? The effect of wood ash on plants

Wood ash is common in the countryside and easy to find. It is a very good fertilizer that has the effect of "replenishing potassium and strengthening roots".

Because it contains high potassium, it can make the plant's root system thicker and improve the plant's disease resistance. However, you must master the right method when using it. If you use it blindly, it can easily cause yellow leaves and stunted seedlings.

Will too much wood ash kill plants?

If you use too much wood ash, the animals will die. Wood ash is actually from burning firewood. It is a quick-acting fertilizer that contains potassium carbonate , but don't use too much wood ash.

You should know that wood ash contains more plant nutrients. This substance can improve the alkalinity of the soil. However, if it is used on chrysanthemums and camellias, it will affect their growth. It may cause the original leaves to lose their luster, the flowers to lose their luster, and in severe cases it may cause withering or even death.

What is the role of wood ash

1. Accelerate rooting

Using wood ash can promote plant germination and accelerate rooting. Some people use wood ash as a substrate, which will add nutrients to the plants and help wounds heal faster.

2. Increase the survival rate

If the transplanted trees eat wood ash, their survival rate can be increased, which can also help prevent leaf fall.

The correct way to use wood ash

1. Sprinkle directly on the surface of the potting soil

Usually, when flower lovers use wood ash, they will choose to sprinkle it directly on the surface of the potting soil. It is also possible to sprinkle the wood ash on the surface of the potting soil, but it is best not to use it in this way for plants that like acid.

Because wood ash itself is alkaline, if you spread too much of it, it will seep into the soil when watering, causing the soil to become compacted. In addition, the iron element cannot be absorbed after the soil becomes alkaline, so the plants will have yellow leaves and weak root systems, eventually resulting in stunted seedlings and yellow leaves. Try not to spread it.

2. Use wood ash for acidic plants

If it is an acid-loving plant, the method we use is very simple. Put some wood ash in a large oil barrel or bottle and soak it for at least 24-48 hours.

You can see that the liquid has a light yellow color. The potassium element in the liquid has been released and the content is not high. We can use it directly to water the flowers.

However, for acid-loving plants, if you water the flowers directly, it is also alkaline. It is recommended that you add some orange peel, lemon peel, etc. when soaking in water.

3. Use after fermentation

After soaking the liquid, pour it out separately and put it directly into another container. After sealing, expose it to the sun for at least two weeks to fully ferment.

The trace elements in orange and lemon peels seep directly into the water and become slightly acidic fertilizer after fermentation. There will be no problem watering acidic flowers with it then.

It can supplement potassium and trace elements, and will not burn the seedlings because it has been completely fermented.
