Expired milk can be used to water flowers, which can supplement the nutrients needed by the plants and promote the healthy growth of the plants. But it cannot be used directly. You can pour it into a relatively sealed empty bottle, then place it in the sun for fermentation. After 2-3 months, add clean water to water it. Be careful not to use it too frequently, and it is best not to use it to water indoor flowers.

1. Can it be watered?

Don’t rush to throw away the expired ones, don’t waste them, they can be used to water flowers. Milk contains more than 100 substances, which can supplement the nutrients needed by plants and promote the plants to grow vigorously, become luxuriant, and have large and colorful flowers. But it cannot be used directly, because untreated milk will emit a lot of heat after being poured on it, which can easily burn the roots of the plant and make it wither.

Before use, you can pour it into a relatively sealed empty bottle, and then place it in the sun for fermentation. Open the bottle regularly to allow the gas inside to escape. Wait for 2-3 months for the fermentation to be completed, and then you can add water to water it.

2. Precautions

1. The frequency of watering should not be too frequent, only once every two months. Too many times will have a negative impact on the plant and cause it to wither.

2. It is best not to use it to water indoor flowers, otherwise the fermentation of milk will produce an unpleasant smell that cannot be dissipated inside the house. It is recommended to water large outdoor flowers and plants. If you want to prevent the smell from evaporating, you can dig a small pit and bury the milk in it.
