Plant ash is the main source of potash fertilizer, and contains more calcium, but it is often alkaline, so it can not be applied to acid-loving flowers, but more suitable for acid-loving flowers, such as pink, geranium, rose, tamarisk, Amorpha, ash and various vegetables.In addition, plant ash is also suitable for raising neutral flowers, which are not strict with soil acidity and alkalinity, as long as the amount of application is not much, such as tulips, hyacinths, Daphne, daffodils, calendula and most other flowers.
1. Production method: Plant ash, as its name implies, is some ashes obtained by completely burning some straws and leaves and cooling them in the air. It is grayish white, and has the effects of supplementing potash fertilizer for plants, improving the resistance of plants, and preventing diseases and insects.
2. How to use: Plant ash can be mixed with soil as base fertilizer, or sprinkled on the soil surface as topdressing. If you want to prevent insects, use plant ash to sprinkle a thin layer around the plant.
3. Application time: If soil is mixed as base fertilizer, it should be applied when pots are changed in spring and autumn.If we do topdressing, it is usually applied before the low temperature comes every year, that is, in late autumn, at this time, fertilization can improve the cold resistance of plants.If it is for insect control, it can be applied at any time.
