coffee grounds
Today, let's introduce some related experience on home flower cultivation. This includes the lessons learned from using coffee grounds, yogurt, milk, soy milk, tea water, and rice washing water as fertilizers. Let's take a look together.
Although I am a gardening beginner, the spirit of daring to try has always accompanied me, leading to many mistakes. Through personal practice and learning from others, I have summarized lessons and experiences for everyone to share~
1. Coffee Grounds: Lesson - It is said that expired coffee grounds make good fertilizer, so I impulsively fertilized all the plants, and now, after a week, 3 or 4 pots have developed pests and diseases. Worse results are yet to be observed, sigh. Experience - Don't sprinkle coffee grounds directly, but use the dregs after brewing as fertilizer. For plants with pests and diseases: Rinse the pot with water twice, then cover it with a layer of fresh soil.
2. Yogurt: Lesson - Using it to water plants directly, during secondary fermentation, it not only produces a lot of heat, easily "burning" the roots (rotten roots), but also easily attracts pests. Experience - Do not water plants directly with yogurt because it is unfermented milk, so you must add a lot of water to the yogurt, dilute it thoroughly before watering, and do not water too frequently, once every one or two weeks is fine. The same goes for milk and soy milk.
3. Tea Water: Lesson - Pouring leftover tea directly onto plants, the tea water ferments in the pot, producing a lot of heat that burns the flowers. Moreover, tea water is alkaline and can change the pH of the soil (most flowers prefer neutral or acidic soil). Experience - Put the leftover tea in a sealed jar, add vinegar and orange peel to change its pH, and after it fully ferments and matures, it becomes good flower fertilizer.
4. Rice Washing Water: Lesson - Using rice washing water to water plants directly can cause the soil in the pot to become compacted over time, hindering the plant's root respiration, and excessive watering can burn the plant's roots. Experience - Homemade rice washing water fertilizer is best after it has been composted and fermented: Place it in a large cola bottle, seal the cap for about a week (depending on the season), occasionally松动 the cap to vent during this period, then dilute the clear liquid with water (70%-80% water), taking care not to spray it on the leaves and flowers but pour it into the soil, generally once a day. Note! This fertilizer is acidic and suitable for azaleas,米兰, jasmine, gardenia, camellias, pothos,巴西木, etc., but not for cacti and other alkaline plants~
