Waste oil works wonders for plants: add a few drops and the leaves grow like crazy

These days, basically everyone has a range hood installed at home, because cooking produces a lot of oily smoke, and without a range hood, this oily smoke would spread throughout the house, polluting the indoor air environment and harming people's health. But after a range hood has been used for a long time, sticky grease stains appear on its body, all from the oil components contained in the air that rises during cooking. These grease stains not only make the range hood look dirty, but also affect its working efficiency, so every so often we clean the range hood. But if there is too much grease left on the range hood, wouldn't it be too wasteful to clean it all off and throw it away? We have a very good solution: use it to grow plants.

1. Some people may ask, don't these waste oils affect air quality, so why can they still be used to grow plants? Won't they affect the plants' growth? The answer is no. These waste oils contain a fairly large amount of nutritional elements, and instead promote plant growth. However, collecting these waste oils is not too easy, because these grease stains are sticky and slippery, and touching them with your fingers makes you uncomfortable. When necessary, you can try using a spoon to scrape the grease off bit by bit and pour it along the edge of the pot, being careful not to cover the plant's root system, because these waste oils are relatively dense and may block the plant roots' breathing.

2. Waste oil looks black, and after collecting it you can first put it into a small bottle. Each time you pour, use a smaller amount; don't pour it all in at once just for convenience, as this will only hinder the potted plant's absorption of water and oxygen. These waste oils are a cheap and easily obtained fertilizer. Used properly, they can make potted plants produce more brightly colored flowers, and plants that were originally withering may also recover their vitality.

3. Waste oil is not suitable for all plants. For example, for plants like jasmine and pothos that are not easy to keep alive in the first place, after being watered with waste oil, the soil is very likely to become compacted. After compaction, the soil's ability to let water penetrate is greatly weakened, and at the same time these plants are not very good at breaking down grease, so the effective substances in the waste oil cannot be absorbed efficiently.

Therefore, for this kind of plant that does not like fertilizer and has fragile roots, do not try waste oil irrigation again; such fussing will only make them die faster. But for plants like kalanchoe and geraniums, which originally have relatively strong survival ability and decent adaptability, waste oil is a fairly suitable nutrient for them,

In this way, you can save the cost of growing plants, and secondly you can make use of waste and reduce unnecessary waste, so from now on everyone should definitely not throw away waste oil anymore.
