Can wood ash be directly mixed with soil to grow flowers? What kind of flowers and plants are suitable for growing?

Since wood ash is a potassium fertilizer , applying potassium to the flower buds can provide potassium for the plants. However, it should be noted that wood ash is alkaline .

Therefore, less fertilizer should be applied to flowers that like acid, such as camellia, jasmine, gardenia, azalea, orchid, lily, coleus, ornamental pineapple, etc. If applied to flowers that like acid, some peel water can be often poured to adjust the pH value of the soil.

The role of wood ash mixed with soil in growing flowers

Plant ash can be directly used to mix soil for growing flowers. Plant ash is a high-quality potassium fertilizer. It is often applied to flowers to supplement potassium for plants. However, plant ash is alkaline. When planting flowers, you should pay attention to some acid-loving flowers. Apply less plant ash to avoid destroying the acid-base balance of the soil, causing yellow leaves and poor growth of flowers.

1. Promote germination

It can effectively increase the temperature of the ground, thereby promoting early germination of seeds (especially for some plants that are difficult to germinate or germinate, they can germinate 7 to 10 days earlier), with a high germination rate, and the growth of flower seedlings will be more uniform.

2. Prevent injury

After pruning the flowers, apply a layer of wood ash on the wound to seal it. This will prevent the wound from rotting and speed up wound healing.

3. Promote rooting

Completely remove the rotten roots, apply wood ash on the wounds, and replant. After about half a month or 20 days, the flowers and leaves will gradually turn green and become brighter.

4. Reduce yellowing and falling leaves

After soaking in water for 8-12 hours, take the upper layer of clear liquid and pour it on the potting soil or land, and then apply fertilizer to the flower seedlings, seedlings, and vegetable roots. The concentration of the plant ash water extract should not be too high, and it is more appropriate to use 1-2 grams of water to 1000 grams of water.

5. Prevent and control pests and diseases

Although using wood ash to control pests is pollution-free, it also has a disadvantage. The effectiveness period is very short, and it only works for a few days. After a few days, the wood ash cannot be used again and must be used continuously.

6. Enhance stress resistance

Because wood ash contains a large amount of free potassium ions, after being absorbed by plants, it can reduce the transpiration intensity of leaves and improve their drought resistance. In addition, before the cold season comes, the plant can absorb enough potassium ions to make the branches and roots stronger, thereby enhancing its ability to resist cold.

Specific method of mixing wood ash with soil

When preparing the soil, grab some wood ash and mix it evenly with the soil. On the one hand, it can provide plants with enough potassium to achieve the purpose of potassium application, and on the other hand, it can remove harmful bacteria in the soil and provide a more harmonious and healthy growth environment for plants.

Pay attention to the amount of mixed soil; about 1-2 grams of wood ash can be added to 1 kg of soil (1 gram or 2 grams of wood ash is actually a lot, as the density of wood ash itself is very small).

Well, in a weakly alkaline soil environment, you can add a small amount, such as pomegranate, wolfberry, cactus, cactus, etc.; for plants that prefer a weakly acidic environment, such as gardenia, azalea, jasmine, etc., you can reduce it slightly.
