How to Use Wood Ash to Cleverly Control Flower Pests and Diseases

Wood ash not only supplies flowers with potassium and other nutrient elements, but also has a fairly good effect on preventing and controlling flower pests and diseases.

Preventing and controlling leaf blight: Take 1 kg each of wood ash, tea seed cake and sulfur powder, and 1.5 kg of lime, crush them into powder and mix them evenly, then broadcast 1.5 to 2.5 g per pot for flowers prone to leaf blight.

Preventing and controlling leaf spot: Take 3 kg of wood ash and 1 kg of quicklime powder, mix and stir them evenly, then broadcast, 40 to 60 g per pot, or sieve and dust, or broadcast wood ash alone.

Preventing and controlling root rot: Wood ash has a very good preventive and control effect on flower root rot. The specific method is to first dig away the soil at the roots, 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, and then cover with soil.

Preventing and controlling powdery mildew: For flowers affected by powdery mildew, dig away the root soil to a depth of 5 to 10 cm at a distance of 5 to 10 cm from the main stem, cover each plant with 0.5 to 3 kg of wood ash, and add a thin layer of soil on top of the ash.

Preventing and controlling seedling-stage diseases: Flower nursery land is 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 dead seedlings. Wood ash can be broadcast along the furrows, at 20 to 25 kg per mu.

Preventing and controlling aphids: Grind wood ash into powder and sieve it, then in the early morning before the dew has dried (or after sprinkling water first) dust the wood ash onto the bodies of the aphids. You can also put the ash in gauze and shake it out, then dust again after three to five days, for 2 to 3 consecutive dustings.
