Proper watering largely determines the overall development of any indoor plants. It is necessary to water not only on time, and competently, but also to use good water for this. Usually we just defend the water, then to use it for watering. Many of this procedure and limited. But often this is not enough. Water must be softened if it is too hard. Namely, such water sometimes flows from under our tap. So, if you live far from a spring with “living” water, and water your indoor plants with what flows from the faucet, then teach yourself water not only to defend. It is also necessary to soften it. The procedure is quite simple and easy to do at home.
The desired ph of water for watering plants. How to achieve it?
Oxalic acid softens water very well. That it should be used for this purpose. When it is exposed, a precipitate forms in the water. This precipitate is calcium, which is present in large quantities in any hard water, as well as its salt. After that, the ph of water is reduced already to the level of 5.5.
For indoor plants, this acid is not harmful in itself. In the soil and the plants themselves, it does not accumulate. Moreover, oxalic acid to a certain extent even heals the earth. It does not allow harmful bacteria to develop, which often attack our houseplants. A good microflora develops in the soil in this way, and this helps the plants to increase their root system.
How to cook this water?
For irrigation, it is best to immediately soften a sufficiently large amount of water. For example, 10 liters. Sorrel acid for 10 liters of water needs only 1 / 5th of a teaspoon. Acid needs to be stirred, and can be watered, even without letting it settle. This is a quick water softening option.
There is a better option. A peculiar concentrate of oxalic acid is being prepared here (per liter it is necessary to take 20 grams), which is then added to the water during irrigation (5 ml of such concentrate is taken). It is convenient to use a teaspoon when preparing this concentrate. Its volume is about 5 ml. It is best to prepare such a concentrate in a non-metallic dish. It must be stored in some secluded place, until the children can reach it. The container with the concentrate must be signed. Its amount is enough for you to soften about 400 hundred liters of water for irrigation.
