First you need to choose the right place for bearded irises. Irises grow and bloom best in sunny or slightly shaded places, on loose, easily heated soils and at the same time fertile and permeable with a pH of 5.5-6.5.
Under trees, where it is dry, they develop very poorly, and on wet and impermeable soils they suffer from diseaseWe can loosen clay soil by digging it with sand or deacidified peat (do not use bark pine), while the sandy soil will be improved by thoroughly mixing it with well-fermented, decomposed manure (this should be done at least a year before planting irises) and heavy clay soil and deacidified peat (in a proportion of 3: 4: 3).
Kosaćce grow very well on tall (30-50 cm), wide beds, separated by a drainage groove. In the event of prolonged drought, especially in spring, water the plants abundantly once a week. Feeding depends on the fertility and the type of soil.If we have used manure before planting, mineral fertilizers can be delivered only after 2-3 years.
These should be preparations rich in phosphorus and potassium, and poorer in nitrogen.We use them in 2 doses: in late autumn or early spring and after flowering. We should also remember about weeding rebate.
