Will plants die if too much wood ash is used?
Main content introduction: Explanation of whether plants will die if too much wood ash is used in the aspect of green plants and flowers. Next, the editor will introduce this.
Will plants die if too much wood ash is used?
Plants will die if too much wood ash is used. Excessive use can change the pH of the soil and also lead to the suppression of plant growth. In fact, wood ash is made from burned straw and is a type of fast-acting fertilizer. It contains potassium carbonate, but it should not be used excessively, and some flowering plants cannot be used.
Wood ash is more common and easier to find in the countryside. It is a good fertilizer that has the effect of "supplementing potassium and strengthening roots."
Because of its high potassium content, it can make the plant's roots thicker and improve the plant's disease resistance. However, it is essential to master the correct method when using it. Misuse can easily cause the plant to develop yellow leaves and stiff seedlings.
Will too much wood ash burn the plants?
Too much wood ash will kill the plants. Wood ash is actually the result of burning straw, which is a type of fast-acting fertilizer. This fertilizer contains potassium carbonate, but do not use too much wood ash.
It should be noted that wood ash contains a lot of plant nutrients, which can improve the alkalinity of the soil. However, if used on chrysanthemums or camellias, it will affect their growth, possibly causing the leaves to lose their luster, the flowers to be dull, and in severe cases, it may lead to withering or even death.
What are the uses of wood ash?
1. Accelerates root growth
Using wood ash can promote plant germination and also speed up root growth. Some people use wood ash as a substrate, which adds nutrients to the plant and can also help heal wounds early.
2. Increases survival rate
If the transplanted trees are treated with wood ash, it can increase their survival rate and also help prevent defoliation.
Correct use of wood ash
1. Sprinkling directly on the surface of the potting soil
Usually, when gardening enthusiasts use wood ash, they choose to sprinkle it directly on the surface of the potting soil. However, it is better not to use this method for acid-loving plants.
Because wood ash itself is alkaline, excessive sprinkling, when it seeps into the soil during watering, can cause the soil to become compacted. Moreover, after the soil becomes alkaline, iron cannot be absorbed by the plant, which will lead to yellow leaves, weak roots, and eventually stiff and yellow seedlings. It is best not to sprinkle it.
2. Using wood ash for acid-loving plants
If it's an acid-loving plant, the method is simple: put some wood ash into a large oil drum or bottle and soak for at least 24-48 hours.
When the liquid has a light yellow color, the potassium in it has already been released, and the content is not high. We can use it directly to water the flowers.
But if it's used directly on acid-loving plants, it is also slightly alkaline. It is recommended to add some orange or lemon peels when soaking in water.
3. Using after fermentation
After soaking the liquid, pour it out separately into another container, seal it, and place it in the sun to晒 for at least two weeks for full fermentation.
The trace elements in orange and lemon peels directly seep into the water, and after fermentation, it becomes a slightly acidic fertilizer. By then, it can be watered on acidic flowers without any problem.
It can supplement potassium and trace elements at the same time without causing seedling burn because it has been completely fermented.
The above is a specific introduction to whether plants will die if too much wood ash is used. I hope everyone will like it!
