The blue Lieschen (Exacum affine) is colloquially often referred to as the Indian violet, although it only has purely visual similarities to the violet native to this country. If this plant is properly cared for, it can delight with a flowering period of up to ten weeks in summer.

How often should the Blaue Lieschen be watered?
The roots of the Blaue Lieschen should not stand directly in the water, but excessive drought can lead to all the flowers being shed very quickly. Optimal conditions for healthy growth and appearance are given when the top layer of soil around the plant dries out a little between waterings, but can never dry out down to the roots. With moderate watering every three days you create ideal conditions for the Blaue Lieschen.
What should be considered when repotting or transplanting the Blauer Lieschen?
Similar to the marigold and other balcony and grave plants, the blue Lieschen is a rather short-lived (biennial) plant that is usually only cared for for one season. Therefore, for many plant lovers, the question of repotting the Blue Lieschen does not arise at all. However, specimens that were in particularly small planters when you bought them can be transplanted into a larger pot at any time without hesitation.
Can a blue Lieschen be cut back?
In horticultural businesses, the Blaue Lieschen is often treated with special growth inhibitors so that it forms a particularly compact and aesthetically pleasing shape. You can easily shorten shoots that are too long (outside the hot mid-summer phase). You should also regularly pluck wilted flowers.
Are there pests that the blue Lieschen prefers to attack?
Occasionally colonies of aphids are observed on the blue Lieschen. Otherwise it is by no means susceptible to pest infestation.
What diseases or care mistakes are common in the Blue Lieschen?
It is not uncommon for site and maintenance errors to lead to the following problems:
- flowers fall off
- Leaves wither
- Formation of gray mold on the substrate surface
While the flowers often fall off when the soil in the pot is too dry, wilting leaves can also indicate a location that is too sunny or waterlogged. A sufficiently ventilated location or a substrate replacement can protect against gray mold infestation.
Should the Blaue Lieschen be fertilized?
The potting soil of blue Lieschen bought in the pot is usually already pre-fertilized, so that additional fertilization is not absolutely necessary if the plant is cultivated seasonally. However, if Blaue Lieschen are grown from cuttings or seeds, they should be fertilized every 14 days between spring and autumn with a liquid fertilizer in the irrigation water.
Can a blue Lieschen be overwintered outdoors?
The blue Lieschen is considered to be very sensitive to frost, but can overwinter in a bright and cool room. Since the plants are short-lived, overwintering is only worthwhile for the purpose of cutting cuttings from the mother plants in January and February.
tips
A blue Lieschen grows particularly well in a bright location, but does not tolerate direct sunlight during midday. So it is better to place it in partial shade or in a spot with morning and evening sun.
