After the seedlings appear, about 5-20 days after sowing the container should be removed from the glass and put it on a window sill. The temperature should be slightly increased to 20-22 degrees. The seedlings do not need bright light as they grow and develop well without it.

How to plant and take care of this plant even a florist with no experience. But not everyone will be able to cope with generative propagation, especially if the seeds have been collected from their own garden. Such a multiplication process is quite complicated and a positive result happens only rarely, because the seeds in the middle belt simply do not have time to mature properly.

It is worth considering whether it is necessary to waste effort and time on collecting seeds, from which, at best, not very beautiful plants will grow. It is much easier to sow purchased seeds, from which you are guaranteed to grow beautiful flowers. But in case you really want to try growing heliotropes from seeds you collected by yourself, you will have to wait until the inflorescence withers, dries out and turns black. Then it is gently plucked, and the small seeds are extracted from it. The extracted seeds should be sorted, dried and poured into a cardboard box for later storage.

Heliotrope in winter

Since it is grown as an annual, the bushes are simply destroyed in autumn because the land will need to be fertilized and recultivated. However, if there is a desire to grow such a plant in the wintertime at home, it is necessary to dig up the mother part of the flower before the first frosts, plant it in a flower pot and bring it home. Heliotrope will need extra light and a cool environment (15-18 degrees), in which case it will bloom for a very long time, filling the room with a unique fragrance. In the spring time, if necessary, cut cuttings can be cut from such a flower and rooted.
