Sand or perlite with peat should be added if it is too dense. For a mixture of own preparation, take: 1 part of the turf ground, 1 part coarse-grained sand or perlite and 2 parts peat or humus (leaf land). You can add coniferous earth. Always use a pot with an opening and drainage. If the soil reaction is alkaline (pH 7.5 and above), the flowers have a white or pink color, depending on the variety; in acidic soil (pH 5.5 and below) the color becomes blue or violet. In order to obtain blue or violet color is to be added to the soil iron-ammonium alum or aluminum sulfate.
Watering The soil must be constantly moist. However, one should also beware of overflow. During growth, it is necessary to water at least 1 time in 2 days, in winter – 1 time in 10 days. Pot should be placed for 10 minutes in a container of water, then let it drain. Blue varieties should be watered with soft water.
