Can expired milk be used to water flowers directly?

Expired milk can be used to water flowers, but it cannot be drunk, as it will make people feel uncomfortable. However, expired milk can be used to water flowers, but it cannot be used immediately, because the protein and fat in the milk cannot be directly absorbed by flowers, which not only cannot promote the growth of flowers, but also will cause adverse reactions.

What flowers are good to water with expired milk

You can use expired milk to water foliage plants and flowering plants, but the milk must be fermented first. Only after the milk is completely fermented can it be used to water the flowers, so that the flowers can better absorb nutrients.

For example, if the rose has black spot disease, you can use fermented expired milk to spray on the affected area. This is because milk contains lactoferrin, which is a good bactericide, so the rose can grow better.

How to water flowers with expired milk

1. Fermentation and watering

If you want to use expired milk to water the flowers, you must first ferment the milk at high temperature. After about 5-7 days, dilute the fermented milk with clean water. After dilution, you can use it to water the flowers.

2. Soil

Expired milk is more suitable for watering plants that like acidic soil, such as gardenia, spider plant, rose, etc. It can keep the soil acidic, provide nutrients to the flowers, and make the flowers grow more vigorously.
