Milk at home will always expire, even if it expires, don't throw it away. Even if people can't drink it, it can be used to add some nutrition to plants. However, it should be noted that milk can't be directly used in plants, and the nutrient content is too high, which is easy to burn plants. We need to make it ourselves before using it.
The easiest way is to find a bucket, then make a few holes in the top of the bucket, and then put the milk and water together. Be careful not to screw the bottle cap too tightly. Usually it can be used for about a week. It is best to add some water before each use. It doesn't matter if the concentration is less, but the most important thing is not to hurt the flowers.
Besides milk, the water used to wash rice at home is also used by plants in the same way. If the smell is too strong, you can put some orange peel in it. These are some homemade nutrient solutions. Eggshells thrown away from the kitchen at home every day can also be used as flower fertilizer, which will be simpler than homemade nutrient solutions.
First break the eggshell, then find a container and put it in the sun for a while, then you can mix the soil directly.
