    At the beginning of the season I planted varietal bearded irises. I was told that they need to be covered for the winter. Is it so?

      — It is impossible to cover irises with any available materials for the winter: diseases develop under them. If you are afraid of losing a valuable specimen, you can pour a pile of sand onto the rhizome. But after the snow melts, it must be shoveled away as soon as possible. In drier climates, for varieties of unknown winter hardiness, spunbond or a thin layer of spruce branches is used to create an air gap between the rhizome and the snow.

      In the fall, carefully inspect the rhizomes and leaf bases for bacterial rot. It would be a good idea to spray lightly affected plants with a suitable preparation without removing them from the soil. Visibly sick ones should be dug up, cleared of soil, processed and transplanted to another place. In the fall, it is better to plant the cured rhizome in a container and leave it to winter indoors under lamps. Such a measure, of course, can suppress flowering, but it will allow preserving a valuable variety, which, being weakened, may die in the ground over the winter.

      Before wintering, remove yellowing leaves and cut green leaves with a wedge to a height of 10-15 cm. This will avoid the gradual death and decomposition of the above-ground parts in the cold season. Although it has been noted that in some cases (say, during rainy weather), such pruning, on the contrary, can provoke bacteriosis, since water penetrates more easily into the base of the leaves.

    Replant irises every 4 years in August. Having dug up a bush, shorten its leaves and roots by 10 cm with sharp scissors, then divide it into divisions and lower each for 5 minutes in a dark pink solution of potassium permanganate. Then rinse the delenki under running water, dry for 10-15 hours in the sun and plant in the ground.
