The best soils for sunflowers are chernozems and fertile loams.
But in the northern regions it is necessary to create an artificial nutrient mixture for them in the garden, otherwise you will not get a strong, healthy plant.
Make straight furrows in the garden bed, and in them holes 4–5 cm deep at a distance of 50–60 cm from one another and place 2 seeds in each (in case one does not sprout). The distance between the rows is 60 – 80 cm.
The greater the distance between the plants, the larger you will get both the seeds and the baskets themselves.
Sunflowers (also known by their Latin name Helianthus) can be grown in a pot.
You need to provide them with a suitable sized container. Some sunflower varieties grow much larger than others, so check the seed package for height information.
Annual sunflower needs regular watering throughout the growing season.
Starting in spring, you should plan to water this plant about once a week.
As the warm season approaches, watering can increase to two to three times a week.
It is necessary to regularly inspect sunflowers and remove wilted flowers and leaves.
This stimulates the formation of new buds and prolongs the life of flowers.
When the sunflower fades, you can transplant it into open ground or a pot.
