How can wood ash be used effectively to control pests and diseases in flowers and trees?
How is wood ash used to control pests and diseases in flowers and trees? You should know that using pollution-free, low-cost, simple and convenient wood ash to control pests and diseases in flowers and trees has remarkable results. Below, the editor of Huinong Network has summarized for flower lovers several methods for how to use wood ash to control common pests and diseases in flowers and trees!

1. Controlling leaf blight
Use 1 kg each of wood ash, tea cake and sulfur powder, and 1.5 kg of lime. Crush them into powder and mix evenly. For flowers prone to leaf blight, scatter 1.5 to 2.5 grams per pot.
2. Controlling leaf spot
Mix 3 kg of wood ash and 1 kg of quicklime powder evenly and scatter it, 40 to 60 grams per pot, or sieve and dust it, or scatter wood ash alone.
3. Controlling root rot
Wood ash has a very good control effect on root rot in flowers. The specific method is: first dig open the soil around the roots and remove the soil around the rotted roots; scrape off the diseased root bark, apply 0.5 to 1 kg of wood ash per plant to cover the roots, then cover with soil.
4. Controlling powdery mildew
For flowers affected by powdery mildew, at a distance of 5 to 10 cm from the main stem, dig away the root soil to a depth of 5 to 10 cm, cover each plant with 0.5 to 3 kg of wood ash, and add a thin layer of soil on top of the ash.
5. Controlling damage at the seedling stage
Flower nursery beds are prone to damping-off, anthracnose and other diseases at the seedling stage. When humidity is high and temperature is low, seedling diseases occur severely and often cause large numbers of seedling deaths. Wood ash can be scattered along the rows, with 20 to 25 kg per mu.
6. Controlling aphids
Grind and sieve wood ash, and in the early morning before the dew has dried (or after first sprinkling water), dust the wood ash onto the bodies of the aphids. You can also put the ash in gauze and shake it out, then repeat after three to five days, for 2 to 3 consecutive applications.
7. Controlling root maggots
When root maggots damage flowers at the seedling stage, using pesticide drenching at the roots can easily cause phytotoxicity. Instead, apply 30 to 40 kg of wood ash in the nursery bed. The application method is: at the seedling stage, scatter the wood ash evenly on the bed surface, then hoe and turn it evenly so that the ash and soil are fully mixed; you can also, before sowing or planting, first apply the wood ash in the furrows, and then sow or plant.
8. Controlling underground pests
During seedling raising, bulbous flower seedling beds often suffer from underground pests such as white grubs. Using wood ash as a base fertilizer for control, or covering seed bulbs with wood ash, can significantly reduce the damage.
That is all the editor of Huinong Network has introduced about how to skillfully use wood ash to control pests and diseases in flowers and trees. If you want to learn more about flowers, please continue to follow this site, Huinong Network!
Using wood ash to control pests and diseases in flowers and trees
Wood ash:It is the residue left after plants are burned. Because wood ash is the ash left after plants are burned, it contains almost all the mineral elements contained in plants. Among them, the most abundant is potassium, generally containing 6% to 12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; next is phosphorus, generally containing 1.5% to 3%; it also contains trace nutrient elements such as calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron and molybdenum.
Wood ash not only can supply nutrients such as potassium to flowers, but also has a relatively good effect on controlling flower pests and diseases.
