Bury this "trash" in the pot and pothos will grow like crazy, and clivia will bloom two or three times a year

Growing flowers and potted plants of course requires fertilizer. Ask the people around you, and you will find that those who make pothos and spider plants explode into a full pot, and who keep clivia and Christmas cactus blooming for decades, are all very good at using fertilizer. And what you would never expect is that the fertilizer they use for their flowers is not the kind sold in stores, but homemade flower fertilizer.
Homemade flower fertilizer, to put it plainly, is just mixing up some fertilizer specially for growing flowers. And most of these homemade flower fertilizers come from "trash" in daily life.
The first type: eggshells
Eggshells have many benefits for growing flowers, because they contain calcium carbonate, which is very good for plant growth. But there is a trick to using eggshells too. I have seen quite a few people just put eggshells on top of the potting soil, which is not advisable. It takes a very long time for the eggshells to break down, so the fertilizer effect is not of much use. The correct way is:
1. Wash the eggshells clean, because if you do not wash them clean, the egg white left on the shells easily attracts flies, and when the weather is hot in summer, it smells terrible in the pot. In serious cases, the egg white flows into the flower's root system, and because it has not been fermented, it easily burns the roots to death.
2. Crush the eggshells, then put them under the sun to bake for half a day. The purpose of this is to disinfect them; eggshells that are not washed clean easily breed bacteria. That harms plant growth.
3. Mix the crushed eggshells with the potting soil at a ratio of 1:5. This way the potting soil gains a lot of nutrients, and the calcium in particular is very good for foliage plants and their growth. Pothos, spider plants, money tree and so on are all suitable for it.
The second type: fish bones, chicken bones, etc.
Fish bones, chicken bones and the like are even better for growing flowers. Bones contain a lot of phosphorus. Phosphorus is an essential element for keeping plant leaves evergreen. The key point is that it can also make yellow leaves turn green again. I do not know if flower lovers still remember that I recommended using monopotassium phosphate for growing flowers a long time ago, because it contains phosphorus.
If your pothos has yellow leaves, your lucky bamboo has yellow leaves, your spider plant has dry tips, black tips, and lucky bamboo yellow leaves, and so on, phosphorus can be used to ease all of it. So from now on, when you have this kind of bone or that kind of bone at home, remember not to throw them away anymore! They are the best for growing flowers!
Using bones to grow flowers also requires treating them before use. First bake them in the sun, then crush them, just like eggshells, and finally stir them into the soil. Some flower lovers may say, then I still have to change the soil for the potted plant, isn't that too troublesome? No worries, you can wait until next spring when you repot and then replace it with the newly mixed soil. Usually you can use "burying" instead. Dig a few small holes in the potting soil and fill these crushed fertilizer materials into them.
The third type: waste oil from the range hood
When cleaning the range hood, you will find that if it has not been cleaned for a long time, the waste oil inside keeps increasing, so many people just throw away the waste oil they clean out at regular intervals. But for people who grow flowers, this is a treasure! Why say that? The nutrients in the waste oil are really no less than any kind of fertilizer sold at the flower market. Range hood waste oil contains peanut oil, olive oil, soybean oil, corn oil and so on, mixed with multiple nutrients. Quite a few flower lovers use it for growing flowers and the effect really is great.
Waste oil for growing flowers basically needs almost no treatment; just take it and use it directly. First pour the waste oil into a bottle, which can be a mineral water bottle, then poke a few holes in the bottle cap with a needle. Along the edge of the potting soil in the flower pot, dig a few small holes and drip the waste oil in. Drip it in once or twice a month. Any plant will start growing like crazy.
Besides the several kinds of household "trash" mentioned above for growing flowers, there are also leftover tea, yogurt, rotted soybean cake and so on, all of which are treasures for growing flowers. I do not know what other little tricks flower lovers usually have for growing flowers; you are welcome to comment below!
