1、 Reasons for pouring tea

The so-called tea naturally has tea, and tea has theophylline, which is weakly alkaline. Watering plants with tea can improve the pH of soil, and weak acidic soil is more conducive to the growth of asparagus. Control the pH value between 6.5 and 7, so that its leaves will grow greener and plants will be more vigorous

2、 Precautions

Although watering tea can promote growth, it should be noted that it cannot be watered directly. It can be used after fermentation. Only when the organic matter in tea is turned into inorganic salt can plants absorb it. When fermenting, put it in a ventilated place. When you smell a bad smell, it means that the fermentation is good. If it is directly irrigated in the basin, bacteria and insects will breed, which will not only be beneficial, but also affect the growth

Because there are nutrients needed for the growth of Asparagus in tea, tea can be placed on the soil and can be decomposed into fertilizer, but pay attention to the amount. Don't put too much to avoid burning roots. In addition, it can also be watered with rainwater or rice washing water, which can also promote growth
