Gardeners of all countries regularly feed their indoor “pets” with both granular and liquid fertilizers . Flowers, having received another “vitamin cocktail”, grow faster. But, unfortunately, the composition of the soil in pots with your pets will not change from this.
Of course, you can buy ready-made soil and add it to pots when transplanting or add it, which is regularly practiced. But more and more often, even with the soil of proven manufacturers, gardeners bring different living creatures into the house, be it caterpillars, beetles or flies. Weed seeds, unfortunately, are also not uncommon.
Many gardeners have become interested in the so-called alternative fertilizers – kitchen waste. They are able to improve the condition and structure of the soil, and certainly do not contain any unpleasant surprises in the form of pests.
Sleepy tea and coffee grounds .
Tea brewing (including herbal tea brewing, mint tea, for example) and coffee really make potting soil lighter. Advantage of use: “neutralize” alkaline soil. The negative side of use: if soil flies have settled in you, the introduction of such funds will dramatically accelerate the rate of their reproduction. So you can use this fertilizer only in the complete absence of this living creature.
Sleeping tea is added when transshipping flowers into large pots and flowerpots. A layer of expanded clay is laid on the bottom, then a layer of sleeping tea (small), sprinkled with earth on top. The plant is transplanted with a lump of “native” land. With this method, plant residues very quickly turn into a light substrate. In addition, they perfectly retain moisture in the soil. But neither tea nor coffee grounds can be called fertilizer in the full sense of the word. These are just soil fillers.
The shell is a source of calcium. But he, unlike nitrogen, potassium and phosphorus, is not a primary fertilizer. The shell, ground into powder, will benefit, provided that it is applied along with mineral fertilizers. This is because most of these fertilizers increase the acidity of the soil, and the shell acts as a neutralizer of this acidity. There is a positive effect – the soil is less acidified. When introducing eggshell into the soil, remember: it decomposes extremely slowly, so do not apply it too much and often, know the measure. Any seedlings will develop slowly (in some cases even die) if you overdo it with this fertilizer. A similar effect is observed in seedlings of tomatoes, peppers and eggplants. Eggshell powder is a fertilizer for stronger plants.
Onion peel .
Once a month, you can pamper your plants with an infusion of onion skins. They should spray plants and topsoil for the purpose of preventive disinfection. Pour the husk with about six cups of boiling water, hold on fire for a minute and a half. Infuse for two hours, strain through cheesecloth and pour into a spray bottle. Spray only with fresh solution, using it all at once (do not store the solution). Almost all plants perceive this solution as a complete fertilizer.
Orange peels .
Used similarly to onion skins. Spraying with a solution of orange peels is a prevention of the appearance of spider mites. The solution is prepared randomly. Fresh or dried orange (and/or tangerine) peels in 6 cups boiling water. We insist 12 hours, filter. Spraying will please you not only with efficiency, but also with a wonderful smell of orange, which will stay in the room for several hours.
Other experiments .
You can often find information that plants can be watered with water left over from washing buckwheat, rice and other cereals, as well as peeled potatoes. It may be useful, but there is usually no particular effect, as a rule. Seed husks can replace drainage, but this is more of a fertilizer for compost pits.
As you can see, all these natural components, of course, will be useful to your indoor plants to one degree or another. But they will never replace fertile nutrient soil .
