Just Sprinkle Some Ash
Gardeners are most troubled by the invasion of diseases and pests, as chemical pesticides can be harmful with limited effectiveness. In fact, there are 7 natural materials in daily life that can effectively eliminate pests and promote plant growth, which are environmentally friendly, safe, and pollution-free!
Three Mineral Material Pest Repelling Methods
Wood Ash for Pest Control and Fertilization in One
Wood ash is rich in potassium, and its alkaline properties can damage the waxy layer of pests' cuticles. Dig 3 deep holes 15cm away from the root of the roses, and after burying 50g of wood ash in each hole and covering with soil and watering thoroughly, it can not only radically treat powdery mildew but also supplement phosphorus and potassium fertilizers to promote flowering.
Bamboo Charcoal for Soil Microecological Regulation
The porous structure of bamboo charcoal can absorb harmful bacteria. Mixing 5mm pieces in a 1:10 ratio into the matrix can significantly reduce the incidence of root rot. Experimental data shows that the survival rate of azaleas using bamboo charcoal increased by 27%.
Cigarette Ash Technique for Quick Aphid Control
The (Y-J) component has a contact-killing effect on aphids. Collect the ash from 20 cigarettes and mix it with 500ml of water, let it sit for 24 hours, and then spray the supernatant. After 48 hours, the aphid elimination rate reaches 92.6%.
Four Plant-Based Pest Control Solutions
Chinese Toon Leaf Natural Insect Repellent
Just Sprinkle Some Ash
Chinese toon leaves contain alstonin, which can interfere with insect nerve conduction. Crush 200g of fresh leaves and soak in 1L of water for 48 hours, filter the liquid and dilute 3 times, then spray it, which can prevent 89% of cabbage worms.
Neem Leaf Biopesticide Preparation
Neem extract has a repellent and insect moulting inhibitory effect. Boil 1kg of fresh leaves with 2L of water and concentrate to 500ml, store for later use. Dilute 1:50 when using, and the mortality rate of red spiders reaches 100% within 7 days.
Capsaicin Physical Pest Control Method
Chop 50g of朝天椒 and boil for 30 minutes, cool the filtrate and add 5ml of dishwashing liquid to enhance adhesion. Spraying weekly can form a pest-repelling film, reducing small black flies by 83%.
Cinnamon Powder Soil Protection Layer
Cinnamaldehyde can inhibit the hatching of insect eggs. Sprinkle 15g/m² of cinnamon powder evenly on the surface of potting soil to form a double physical and chemical barrier, reducing ant invasion by 95%.
These natural materials not only solve the problem of diseases and pests but also provide abundant mineral nutrients. It is recommended to rotate different methods every month, which can prevent pests from developing resistance and comprehensively supplement nutrients, allowing plants to grow robustly in a safe environment.
