Swamp Iris - Care, propagation

The Content Of The Article:

The Swamp Iris, which is also called Yellow Iris, is a plant that is classified as particularly protected. Although their stock is not endangered, but protection is still hardship. The large, showy yellow flowers appear from late May to June.
In the wild, they are found mainly on the banks and siltation zones of stagnant and flowing waters, in fens and in riparian forests. At home garden pond, if it finds ideal conditions, the Yellow Swamp Iris can multiply quite quickly and lush and especially with small ponds, sometimes a plague.
The swamp iris is poisonous and in all parts. The highest concentration of toxins is found in the rhizomes. These also contain tannins. The plant is not highly toxic, but caution is still required.
The location of the marsh iris should be sunny to light shady. It is important that it is wet to damp. The plant thrives best in the water. A depth of around 20 cm is ideal, but it can also cope with a water level of up to 40 cm. However, it does not bloom then. In addition, the marsh irises need plenty of space.
plant substrate
The Yellow Iris prefers heavy clay soils that hold the water for a long time. Also, it gets along well with muddy, nutrient-rich alkaline soils. It is planted in spring or autumn. The rhizomes are then buried just below the surface of the earth.
Pouring and fertilizing
The Swamp-Sumpflilie tolerates, if it is not in the water, sometimes longer drought. Drying out during the time the flowers are planted, however, affects the flowering. Fertilization in the spring when sprouting ensures a particularly rich flowering. However, if the plants are in the pond, you should work very carefully with fertilizer. Plant fertilizer does not belong in the pond. If it is not on or in the pond you should fertilize abundantly, the plants love nitrogen.
To cut
In autumn, the marsh iris is cut about hand-high.
The swamp iris can be pulled by seeds. The seeds germinate only in sufficient light. In addition, seed must be sown immediately after seed season in autumn. The yellow iris is a cold germ and a dark germ. The seeds are first placed on a paper for a few days in the refrigerator and then sown. They should be abundantly covered with soil. This must be kept slightly moist evenly. In ideal conditions, the seeds germinate quite fast, within a few days. Another type of propagation occurs through the division of the rhizomes. These can be shared except during flowering.
The Yellow Swamp Iris can hibernate at its location in the garden or in the pond. It needs no extra winter quarters.
