Can expired milk be used to water flowers? What other ways are there to water flowers?

1. Is it possible?

Expired milk can be used to water flowers, but it cannot be used directly; it must be fermented first. Otherwise, if you pour it directly into the soil in the pot, it will soon produce an unpleasant smell, and the heat emitted will easily burn the roots and affect growth. When fermenting, pour it directly into a container, add a small amount of water, seal it and expose it to the sun. It can be used after about a month. There will also be a bad smell at this time. It is recommended to ferment it for a longer period of time. The smell will become lighter over time.

2. Watering Methods

1. Overnight tea: Overnight tea is harmful to the human body and should not be consumed, but it can be used to water flowers. Because it is acidic water, it can promote the growth of some plants that prefer acidic soil. However, you still need to observe the moisture level of the soil before watering. Do not water blindly, otherwise it will affect the growth.

2. Rice washing water: Rice washing water contains many trace elements that can promote plant growth. However, it must be fermented before use, otherwise it will burn the roots and be detrimental to growth.

3. Boiled water: You can also use boiled water, which is easier to absorb than directly using tap water. It's like water that has been exposed to the sun, which can make the plants grow more vigorously.
