Elegant violets are attractive to most flower growers for their bright flowers, ease of reproduction, and small size. For violets, two important soil factors are of particular importance: chemical composition and mechanical composition.

Chemical composition and acidity of soil for violets
Everyone from the school chemistry course knows the concept of acidity. This indicator is very important for growing violets. These plants thrive on slightly acidic soils. They do not tolerate soil with a pH significantly less than 7.0 or highly alkaline, with a pH of more than 7.0. The optimal acidity index should be no less than 6.0 and no more than 6.5.
If the soil is strongly acidic or strongly alkaline, the assimilation of mineral and organic substances is disturbed in the plant, growth slows down, even the color of the leaves changes. If the pH of the soil is 4.5, then even with a sufficient content of nitrogen and phosphorus, their assimilation stops.
Nitrogen-phosphorus starvation sets in. The buds fall off without opening. It is detrimental to the flower and prolonged stay in soil with a pH of more than 8.5,
Important! Some varieties of violets show acidic soil for brighter color of flowers. If the soil is highly acidic, then the young leaves will curl. In an alkaline environment, the leaf plates lose their color, turn pale, the tips of the leaves become brown.
You can check the acidity of the soil for violets with a special device or the following folk methods:
- take a small amount of soil
- split the soil in two
- put in a dish, glass or ceramic
- moisten the soil
- drip vinegar - if the soil starts to sizzle, then its reaction is alkaline
- sprinkle the soil with soda - if the release of gas bubbles has begun, then the soil is acidic;
- if there is no reaction, then the soil is neutral
At home, you can lower the acidity with dolomite flour, and increase it by adding peat to it. Of the chemical compounds in the soil, the following must be present:
- nitrogenous substances
- potassium salts
- phosphorus compounds
Flowers cannot do without macro- and microelements:
When acidity changes, assimilation is disturbed in the first place:
- nitrogen - leaves brighten
- phosphorus - buds do not appear, growth stops, the color of the leaves changes
- potassium - the phenomenon of chlorosis of the leaves and the dying off of the edges of the leaf plates is observed
The acidity and chemical composition of the soil is not constant. They can change over time. Therefore, any change in the shape, color of the leaves, growth retardation and lack of flowers should be a reason for checking the acidity. In addition to the chemical composition, the mechanical characteristics of the soil also affect the growth of violets.
The main components of the soil for violets
A soil mixture for violets should have the following properties:
- moisture permeability
The basis of the soil can be the earth:
- leafy, it is harvested under deciduous trees and shrubs
- sod, harvested in places where perennial grasses grow
High-moor peat and coniferous soil are used as a filler, which is harvested under coniferous trees after removing the top layer of needles. To add to the soil, take:
- vermite - special hydromica, provides moisture retention up to 500%
- perlite - granular granules from kremzem, can be used instead of sand
- charcoal - fine and coarse fraction, regulates humidity and adsorbs unwanted substances
- sand - acts as a baking powder
- expanded clay - it is suitable for creating a drainage layer

In addition to the above components, in some cases, you can take sphagnum moss, coconut fiber. Despite the fact that the trading network offers a very large assortment of ready-made mixtures for violets, it is possible, and sometimes necessary, to compose the soil mixture yourself.
DIY soil for violets
Many growers, who do not trust ready-made mixtures, purchase the necessary ingredients in specialized stores and prepare the soil for violets with their own hands.
Mix for violets No. 1
- leaf earth 1 tsp
- peat 2 tsp
- charcoal 1/2 tsp
- moss 1/2 h
Mix for violets No. 2
- sod land 1 tsp.
- peat 3 h
- vermiculite 1 tsp
- charcoal 1/2 h
When preparing the mixture yourself, it is important to take measures to disinfect those parts and components in which pathogenic microorganisms easily settle and multiply. This is primarily land, peat and moss. When growing violets in small pots, one must not forget that the soil in them is very quickly depleted and transplant flowers in a timely manner.
