Clever Use of Plant Ash to Prevent Flower Pests and Diseases, and Its Many Remarkable Applications

Plant 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.

Controlling Leaf Blight

Take 1 kg each of plant ash, tea cake and sulfur powder, and 1.5 kg of lime, crush into powder and mix evenly, then scatter 1.5 to 2.5 grams per pot on flowers prone to leaf blight.

Controlling Leaf Spot

Mix 3 kg of plant ash with 1 kg of quicklime powder evenly and scatter it, 40 to 60 grams per pot, or sieve and dust it, or scatter plant ash alone.

Controlling Root Rot

Plant ash has a very good control effect on flower root rot. The specific method is to first dig open the soil around the roots and clear away the soil around the rotted roots. Scrape off the diseased root bark, apply 0.5 to 1 kg of plant ash per plant to cover the roots, then cover with soil on top.

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 trunk, cover each plant with 0.5 to 3 kg of plant ash, and add a thin layer of soil on top of the ash.

Controlling Seedling-Stage Diseases

Flower nursery plots 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. Plant ash can be scattered along the rows, at 20 to 25 kg per mu.

Controlling Aphids

Grind plant ash into powder and sieve it, then in the early morning while the dew is not yet dry (or after first sprinkling water) dust the plant ash onto the bodies of the aphids. It can also be shaken out from a gauze bag, and scattered again every three to five days, for 2 to 3 times in a row.

Controlling Root Maggots

When root maggots harm flowers at the seedling stage, using pesticide as a root drench can easily cause phytotoxicity, so 30 to 40 kg of plant ash per mu can be applied in the seedling plot. The application method is to evenly scatter the plant ash on the bed surface at the seedling stage, then hoe and turn it evenly so that the ash and soil are fully mixed. It can also be applied in the furrow before sowing or planting, and then sowing or planting is carried out.

Controlling Underground Pests

When raising seedlings, bulbous flower seedling plots are often harmed by underground pests such as white grubs. Using plant ash as a base fertilizer for control, or covering the seed bulbs with plant ash, can significantly reduce the damage.
