We suggest you find out what you need to feed your indoor plants between flowering seasons.
Regular activated carbon will help you with this.
Most often, this fertilizer is used by orchid owners. The cut areas are treated with activated carbon powder.
The product is cheap and has many functions.
It acts as a sorbent, removes excess moisture and toxic substances. Coal neutralizes excessive soil acidity, removes heavy metal emissions that enter through open windows with dirty air.
For other plants, coal can be applied in two ways, wet and dry.
For a medium plant, you need to crush a couple of tablets of activated carbon. Make holes a couple of centimeters deep and pour the carbon in there. It needs to be covered with soil and the soil moistened.
There will be no effect if you simply place the tablets on the soil surface.
For the wet method, you need to dissolve several tablets in a small amount of water and water the flowers. You need to make sure that all the fertilizer is well absorbed.
In addition to activated carbon, you can feed flowers with infusions of banana or tangerine peels.
You need to cut one banana or tangerine peel and pour 1 liter of boiling water. Let the solution sit for three hours, then water the flowers. The solution should not be hot.
