Since annual rudbeckia is a very heat-loving plant, it can be planted directly in a flowerbed only at the end of June, when the ground warms up to + 20 degrees.
Then it will only be able to bloom in August.
Therefore, in the northern regions we recommend that you grow it through seedlings.
Why is Rudbeckia useful
The plant is valued both for its decorative qualities and for its ability to provide immunostimulating, antiseptic, and antispasmodic properties.
The therapeutic effect of rudbeckia is due to the biologically active substances it contains.
First, these are the coumarins scopoletin and umbelliferone.
What soil is needed for rudbeckia
Rudbeckia is unpretentious and, in principle, does well even on clay soils.
Nevertheless, for active development, it is still better to offer it fertile, water- and breathable soil with neutral acidity.
How does the rudbeckia flower reproduce
Reproduction: almost all rudbeckias, except for terry varieties of perennial species, are propagated by seeds, which remain viable for 3 years.
Perennial species can reproduce by dividing the rhizome.
How often should you water Rudbeckia
Unlike cold weather, rudbeckia tolerates drought and high air temperatures very poorly.
Therefore, in order to prevent the death of the plant, it needs to be watered often.
In summer, when it is very hot, you may even need to water twice a day - in the morning and in the evening.
