What flowers is wood ash suitable for growing? The suitable flowers are all here

Wood ash is a traditional fertilizer source for growing crops. It is rich in elements such as calcium, magnesium, iron and phosphorus, and can provide plants with ample nutrients. Many people like to mix some into the soil when growing flowers, so what flowers is wood ash suitable for growing?

1. What flowers is wood ash suitable for growing?

Wood ash is suitable for growing flowers that do not like acidic soil, such as wisteria, winter jasmine, lilac, staghorn sumac, silk tree, oleander and forsythia. This is because wood ash is the residue left after herbaceous plants are burned. It is rich in elements such as potassium, calcium and phosphorus, and is alkaline. It cannot be used for plants that like an acidic environment, because it will make the soil alkaline.

2. What are the benefits of using wood ash to grow flowers?

1. Promotes germination

After sowing flowers and plants, covering them with 1-2 cm of wood ash can effectively raise the soil temperature, keep the soil loose, prompt the seeds to germinate 7-10 days earlier, and make the flowers and plants grow robustly and evenly.

2. Speeds up rooting

During the transplanting of flowers and trees, using wood ash thoroughly mixed with organic fertilizer as a base fertilizer, or mixing 5-20% wood ash into prepared nutrient soil, can increase the absorbability of the fertilizer, promote wound healing and raise the survival rate of transplanted flowers and trees.

3. Prevents disease and controls pests

Spraying a 3-5% wood ash extract also helps control pests such as aphids and red spider mites.

4. Prevents leaf drop

Spraying an 8-15% wood ash extract during the growing season of flowers and trees, as a foliar top dressing, can improve the photosynthesis of the leaves, prolong the growth period of the leaves, make the flowers and foliage more beautiful and improve the ornamental effect.

5. Prevents bleeding

For flowers and trees prone to bleeding, such as peaches, figs and grapes, applying fresh wood ash to wounds caused by pruning or repotting can control the bleeding, prevent the wounds from becoming infected and rotting, and promote healing.

6. Enhances resistance

When transplanting flowers and trees in dry places, continuously spraying a 3-5% wood ash extract can improve their drought resistance. This is because wood ash contains a large amount of free potassium ions, which can reduce the transpiration intensity of the leaves, promote the transport of carbohydrates and enhance the ability to resist drought and high temperatures.

Overall, wood ash is alkaline and is suitable for growing flowers that do not like an acidic environment. It can effectively promote rooting and germination and prevent pests and diseases. For example, wood ash can be used when growing flowers such as oleander, silk tree and winter jasmine.
