Use expired milk to water flowers directly

Expired milk cannot be used directly to water flowers. If expired milk is not fermented and is used directly to water flowers, it will not only burn the roots of the flowers, but also attract some small insects foraging, which is not conducive to the growth of flowers. Therefore, expired milk must be fermented before it can be used to water flowers.

The pros and cons of watering flowers with expired milk

Expired milk is rich in organic matter, calcium, iron and other minerals, which can supplement the nutrients needed for flower growth and promote the growth of flowers.

However, expired milk will produce a strong odor after fermentation. If you are growing flowers indoors, you should never use expired milk as it will pollute the surrounding air.

How to water flowers with expired milk

First, you need to seal the expired milk and place it outdoors in a well-lit place for about 6-7 days. After it ferments on its own, you can use it to water the flowers.

The purpose of doing this is to prevent expired milk from fermenting in the potting soil of the flowers, to prevent the generation of a large amount of heat that would burn the roots of the flowers. Water the flowers after the expired milk has completed fermentation, so that the effective ingredients in it can be fully and quickly absorbed by the flowers, thereby promoting the growth of the flowers.
