Use these things for growing flowers and they work even better than fertilizer - the flowers will shoot right up

In summer, nothing really keeps, because the temperature is just too high. Anything you just bought that you don't finish in a day will definitely go bad the next day, which is such a shame. Actually, if someone in the house grows flowers, there's no need to waste them - take them and make flower fertilizer, and the effect is amazing; in minutes you'll have the whole pot bursting with growth.
Watermelon rind
First remove the red flesh from the watermelon rind; only the green part is needed. Then cut it into small cubes, find a clean plastic bottle, put the cut cubes into the plastic bottle, seal it up, and place it in the sun to bake. Every 3-4 days, open the bottle cap to let it breathe. In summer, it will basically ferment successfully in about a month. Then mix the fermented solution with clean water evenly at a ratio of 1:20 and use it directly to water the plants. Watermelon rind is rich in nitrogen, which can make plant leaves big and shiny.
Apple peel
First collect the spoiled apples, then cut them into small cubes, find a clean plastic bottle and put them in; you can also put the cores in. Finally add some water, with the water level above the apples, seal the plastic bottle, and let it soak for about 24 hours. Then dilute the solution with clean water at a ratio of 1:1, and pour it directly onto the potting soil of acid-loving plants, so you can change the soil's acidity and alkalinity.
Tomatoes
First collect the bad tomatoes from home, gather them up, chop them, and put them into a clean plastic bottle. Then add an appropriate amount of rice-washing water, shake it evenly, seal it, and put it in the sun to ferment. In summer, it will basically ferment successfully in about 1 month. Stir the solution with clean water evenly at a ratio of 1:50, and pour it on acid-loving plants; it can effectively adjust the soil's acidity and alkalinity.
