    Once I sowed the seeds of the perennial rudbeckia shiny, I never cease to admire it. Beautiful stately bushes are decorated with many yellow “daisy” flowers, which delight with beauty for a long time. Rudbeckia is unpretentious, but I still adhere to some rules.

    At the beginning of the growing season I feed the flower. Dissolve 10 tbsp in 1 liters of water. potassium sulfate, nitrophoska and Agricola-7. On average, I pour 1 liters of nutrient solution per 3 square meter. After half a month I give a second feeding with the same mixture.
    During prolonged heat and drought, I water the plant often (in the morning or evening).
    I tie tall varieties to a support.
    When the flowers fade, I remove them.

    For the winter, I cut off the above-ground part to the soil level and sprinkle it with a layer (5-7 cm) of humus or, in case of a winter with little snow, cover it with dried grass or spruce branches.
    Bushes older than five years old develop dense growth and lose their decorative appearance. I divide and plant such specimens. I do this in the spring, before the active growth of the perennial, or after flowering.

    If rudbeckia is sick
    For me, rudbeckia has become just a godsend: not only does the plant not require special care, it can also grow in partial shade.

    If a white coating appears on the leaves and stems of rudbeckia, resembling flour (powdery mildew), I spray the bush with a 1% solution of colloidal sulfur (100 g per 10 l of water) or a solution of copper sulfate (80 g per 10 l of water).
    Sometimes orange or brown raised pads can be seen on leaves, stems and shoots - pustules of rust fungus.
    Therefore, for prevention during the growing season, I treat the plants with 1% Bordeaux liquid three to four times with an interval of two weeks.
