These "3 kinds" of things can be picked up on the side of the road
Does flower maintenance require long-term purchase of fertilizer? In urban green belts, there are neglected natural nutrient sources. This article reveals the scientific application methods of three common road materials, allowing plant maintenance to achieve zero-cost and efficient growth, helping you easily create a flourishing garden.
One, earthworm dung: the king of natural slow-release fertilizers
Ecological value and ingredient analysis
Earthworm dung contains 18 amino acids and trace elements such as nitrogen, phosphorus, and potassium. Its unique granular structure can increase soil water retention by 23%. Each gram contains 280 million beneficial microorganisms, far exceeding the microbial content of ordinary organic fertilizers.
Advanced processing techniques
It is recommended to use a three-step processing method: ultraviolet disinfection for 48 hours → sieve to separate impurities → pre-mix with coconut bran at a 1:3 ratio. When repotting in spring, mix it into the matrix at a 15% ratio, which can increase the duration of the rose flowering period by 40%.
Two, pine needles: experts in pH adjustment

Physical improvement principle
Tests have shown that the porosity of matured pine needles reaches 68%, 12% higher than that of perlite. The tannic acid they contain can maintain the soil pH value between 5.5-6.5, especially suitable for acid-loving plants such as gardenias and azaleas.
Innovative application solutions
Make pine needle fermentation liquid: 3kg pine needles + EM bacteria agent + 10L water, seal and ferment for 30 days. After diluting 50 times and spraying, it can increase the chlorophyll content of ornamental plants by 27%.
Three, willow bark: root activator
Bioactive substance analysis
Fresh willow bark contains 0.12% salicylic acid, a natural alternative to aspirin tablets. The humic acid produced by the decomposition of lignin in its bark can enhance the plant's resistance to adversity.
