Simple DIY organic fertilizer methods for home gardening that keep flowers blooming continuously
Actually, when growing flowers and vegetables at home, you don't need to buy fertilizer. You can make fertilizer yourself from readily available household waste. And it's especially rich and effective. The method is very simple, you'll get it at a glance.

If you're making flower fertilizer at home, just do it however you like. Everyone's method doesn't have to be the same. Do whatever is convenient.
My method is like this:First prepare a flower pot, or an empty oil jug. Then put a regular layer of ordinary garden soil at the bottom. That's soil brought back from a vegetable garden or field. Then pile leaves, fruit peels, vegetable leaves, kitchen scraps, and other leftover food scraps on top of the soil surface.

Also, shrimp shells and eggshells, which are rich in potassium fertilizer, are best not thrown away. Try to crush them up a bit, as they ferment more easily. Then spread a layer of garden soil on top. You can also add some coal cinders or sand, either is fine.

You can also add some earthworms, cow manure, sheep manure, chicken manure, and the like, then cover with a thicker layer of soil on top. About 10 cm thick. Press down gently.

Pour water on top, then seal it well. For an empty oil jug, just put the lid on, leaving a small gap; for a flower pot, cover it with a tile or seal it with plastic sheeting. Because there's soil plus a cover, there's not much smell.
During this time, if the flower pot still has space, or the oil jug isn't full yet, you can keep adding fallen leaves, fruit peels, vegetable leaves, eggshells, and so on, then cover with soil again, just like making a sandwich.

After three months or a little longer, through full decomposition and fermentation, it becomes highly nutritious fertilizer soil.

Whether used as a base fertilizer, or applied as a top dressing, it's both loose and airy and rich.
For growing flowers, vegetables, fruits, and potted plants, the results are awesome! Flowers bloom non-stop!
