What flowers are suitable for growing wood ash and how to use it

1. What flowers are suitable for growing wood ash?

Wood ash is the main source of potassium fertilizer and contains a lot of calcium, but it is often alkaline, so it cannot be applied to acid-loving flowers. It is more suitable for alkali-loving flowers, such as carnations, geraniums, roses, tamarisks, Amorpha fruticosa, ash trees and various vegetables. In addition, wood ash is also suitable for growing neutral flowers. This type of flowers is not very demanding on the pH of the soil, as long as the amount applied is not too large, such as most flowers such as tulips, hyacinths, daphnes, daffodils, marigolds, etc.

2. How to use wood ash

1. Production method: Wood ash, as the name suggests, is the ashes obtained after some straw and leaves are completely burned and cooled. It is grayish white in color and can supplement potassium fertilizer for plants, improve plant resistance, and prevent diseases and insects.

2. How to use: Wood ash can be mixed with soil as base fertilizer, or you can sprinkle a handful on the soil surface as topdressing. If you want to prevent insects, just sprinkle a circle of wood ash around the plants, a thin layer will do.

3. Application time: If mixed with soil as base fertilizer, apply it when repotting in spring or autumn. If you want to apply top dressing, it is usually done before the arrival of low temperatures each year, that is, in late autumn. Applying fertilizer at this time can improve the plant's cold resistance. If it is for insect control, it can be applied at any time.
