Don't throw away these kinds of water - they're wonderful for watering flowers. The plants grow new leaves and blooms, and their growth is a delight to see.

For friends who love growing flowers, everyone knows that whether plants grow well and thrive depends on fertilizing.If you can't find fertilizer for your potted plants, the rice-washing water at home, the water from boiling soybeans, the water from your fish tank, and expired milk can also serve as fertilizer. The plants grow vigorously, put out many tender buds and new leaves, and bloom abundantly!

The water from boiling soybeans at home, or the water left after soaking mung beans, shouldn't be poured away either. Dilute it and use it to water flowers - it's rich in nitrogen fertilizer.

In particular, after soybeans are cooked, they can serve as the best organic fertilizer for potted plants. If you have expired soybeans at home, add water and boil them for more than two hours, until the soybeans crumble at a pinch, then put them together with the soybean water into an empty oil jug, add some water, put the lid on, and after a month you can use this water, diluted, to water flowers.

The plants grow lush with branches and leaves. It's especially good for growing snake plants (Sansevieria) - put some around the edge of the pot and many little pups sprout up.

Expired milk can also be used as fertilizer, but if you pour the milk directly into the flower pot, not only will it fail to become fertilizer, it will actually have the opposite effect, because it will curdle and form a skin in the pot, and if you water with too much it will burn the roots and yellow the leaves, leave a strange smell on the soil surface, breed small insects, and so on.

The correct way isto put the expired milk or the okara left after making soy milk into a drink bottle or empty oil drum, put the lid on, and place it in a warm, sunny spot. After fermenting for about a month, dilute it with water and use it to water flowers. Milk is rich in phosphorus and potassium fertilizer, which can promote more blooming in plants. Watering this way also leaves no smell, and it's easily absorbed by the plant roots without burning them.

One flower-growing friend used this milk diluted with water to water a pothos (Epipremnum aureum), and the pothos kept putting out tender new leaves, growing fatter and fatter.

Rice-washing water can also be made into fertilizer this way. Just put it straight into a drink bottle, ferment it for a month, and it's great for watering flowers.

It's especially suitable for some woody flowering plants and herbaceous flowering plants. They grow many new leaves and put out many flower buds.

If you keep goldfish at home, don't pour away the fish tank water from your regular water changes - you can use it directly to water spider plants, gardenias (Gardenia jasminoides) and other plants. It's all quite good, both eco-friendly and hygienic and convenient.
