Can tea dregs be used to water plants? The correct way to use tea water for watering flowers
Many people think that using the leftover tea water to water plants can provide them with nutrients. In fact, tea water contains a high amount of caffeine and alkaloids, which can make the soil alkaline, affecting the growth of plant roots and causing root burn. Moreover, tea dregs not only affect the appearance but also attract insects, doing more harm than good to the plants.
Tea dregs, coffee grounds, and eggshells can also be used as fertilizers, but they should not be used directly as fertilizers on the soil surface; they need to be fermented first. Tea water ferments very quickly, usually becoming slightly acidic after being left overnight. This can be used to water plants that prefer acidic soil, such as roses, chrysanthemums, and cacti. However, it is important to only use the tea water and not pour tea dregs into the flowerpot, as poor ventilation can easily cause the dregs to mold, leading to plant rot and insect infestation. Tea dregs naturally decomposing in the flowerpot can also harm the plant roots.
The above-mentioned tips about using tea dregs to water plants and the correct way to use tea water for watering flowers are small experiences in life that we hope will be helpful to you in your daily life!
