Flowers aren't picky eaters; use a little fruit peel as fertilizer and they'll grow vigorously

These days everything is expensive at the supermarket, and you can't even bear to throw away the peel of what you buy, after all, you paid for it! But things like durian, or yam peel, you can't eat them even if you want to! But if people can't eat them, you can feed them to the flowers!
Durian peel
People who don't like durian think durian is ugly, but it clearly smells great! The most enjoyable way to eat durian is to put the whole thing in the fridge, chill it slightly, then open it while the cold air is still rising off it - it's so sweet and creamy, really delicious! You need to process the leftover peel like this before you can use it to grow flowers!
Find a fairly sharp knife or scissors, cut it into small pieces, and leave it in the sun to dry out - you must wait until the moisture in the peel has completely evaporated! This is because durian peel contains a lot of woody material, and once dried it works much like ordinary leaves and tree bark!
After drying, just lay it directly at the bottom of the flower pot, and it does a great job of draining water and letting air through.
Yam peel
Yam is also a good thing; many people like to buy iron stick yam and steam it to eat directly! The peel of a cooked one is useless! Before cooking, the yam peel you scrape off can be used! Before planting flowers it needs to be fully composted.
If you've already decided what flowers to plant and have already chosen the flower pot, you can compost the fertilizer right inside the pot! First put ceramsite soil or other drainage material in the bottom of the pot, then cover with a layer of soil, then spread the yam peel flat on the soil, cover with soil, add yam peel, and repeat until the pot is full.
Just put the flower pot out in the sun, and after about a month the yam will be fully composted in the soil, and you can plant directly in the pot!
