To decorate a pond or other small reservoir, marsh iris, a perennial plant, is perfect, some specimens of which can be 180 cm in height.
In nature marsh iris found in wet meadows, in floodplains, on the banks of water bodies throughout Europe, it has either yellow or blue flowers that begin to appear from the end of June. The plant is durable and unpretentious.
Iris should be planted in a container with soil, deepening by ten centimeters and shortening by a third all the leaves and roots and then immersed in a permanent place, the plant should be planted in shallow water, on soil that is often moistened, or on the shore of a reservoir from August to September. It is better to choose a place that is sunny and sufficiently protected from the piercing wind, but if this is not possible, partial shade is also suitable for marsh iris. The leaves of the plant should be pruned every fall. Marsh iris is quite winter-hardy, but some varieties can freeze slightly, in this case the container with the plant should be buried more deeply into the soil.
The main thing in care and reproduction
The main condition for flowering and decorative appearance of marsh iris is moisture. It perfectly tolerates flooding, but overdrying the soil is destructive for it. It is fashionable to feed with nitrogen fertilizers in the spring.
Iris marsh can be propagated by dividing the bush or by seeds. If there is no need for reproduction, then it is necessary to cut the seed pods before they open, so that self-seeding does not occur.
For propagation by seeds, they are sown in the fall in the ground to a depth of three centimeters. For reproduction by dividing the bush, you need to divide the bush in August or spring and plant it in a permanent place, this can be realized no more than once every five years.
