The editor introduces the topic of whether wood ash can be used as flower fertilizer, and the following is a detailed introduction.
Can wood ash be used as flower fertilizer?
Wood ash can be used as flower fertilizer. Its main component is potassium carbonate, containing 6-12% potassium, 1.5-3% phosphorus, and trace elements such as calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron, and molybdenum. These are beneficial for the growth and propagation of flowers, but should not be used in excess to prevent fertilizer damage.

Wood ash used directly as flower fertilizerWood ash cannot be used directly as flower fertilizer; it must be fully decomposed before being used as fertilizer, otherwise it will burn the roots and seedlings, affecting plant growth. Moreover, wood ash is nutrient单一, so it is recommended to use water-soluble fertilizers, which not only have good water solubility but also contain rich nutrients.
Wood ash suitable for what flowersWood ash contains a high amount of potassium fertilizer and is alkaline, making it suitable for alkaline soil-loving plants, such as pomegranate, elaeagnus, oleander, forsythia, osmanthus, wolfberry, hibiscus, seaside hibiscus, wisteria, spring rose, lilac, Japanese apricot, scholzia, catalpa, fig, and tamarisk.
Using wood ash as flower fertilizer
Put the wood ash into a container, add enough water to cover it, leaving some space, then slightly tighten the lid to allow for ventilation. The length of time for composting depends on the season; in the summer, high temperatures make it easier to ferment, and it can be ready in 1-2 months, while in the winter, it needs to be composted until the following spring.
Precautions when using wood ash
Wood ash should not be mixed with ammonium nitrogen fertilizers or organic farmyard manure to avoid nitrogen volatilization, nor should it be mixed with phosphorus fertilizers to avoid phosphorus fixation, reducing the fertilizer's effectiveness. Since wood ash is alkaline, it can be applied to acidic or neutral soils and can be used as a base fertilizer, seed fertilizer, and top dressing, as well as a covering material for seedlings and seedlings.
That's all about whether wood ash can be used as flower fertilizer. I hope this article can bring you some help!
