In order for irises (also called irises) to thrive in the garden, they need the right location. We show when and how to properly plant the rhizomes and bulbs of the iris.
If you want to plant the decorative irises or irises, you should first choose the right time and location. We will show you what is important and why the persistence organs of the iris play an important role in the location.
Planting irises: the perfect time
The ideal time to plant the iris is between July and October. Late planting in November or spring planting in March are also possible.
The right location for planting irises
Iris plants love the sun and should be planted in full sun, warm. There are two types of iris on the basis of their persistence organs:
- Onion Iris: It is known by this name, although in reality it does not form bulbs at all, but tubers. Onion-iris species need a lot of moisture.
- Rhizome iris: It has rhizomes as permanent organs. Rhizome irises tend to prefer dry to normally moist soils and are sensitive to too much moisture.
Therefore, when buying irises, pay attention to which organs of persistence are present. Both the onion iris and the rhizome iris thrive on loose, well drained, humus-rich and nutrient-rich garden soil. Irises are also suitable for rock gardens.
The Sword Lily (Iris pseudacorus) and the Japanese Sword Lily (Iris ensata) have slightly different location requirements, as their names suggest. They need moist soil, wet in spring, to thrive. They feel comfortable on the edges of ponds as well as on loamy soils.
This is how you plant the rhizomes and bulbs of Iris
When the right location has been found, the earth must first be loosened up a little. You can also work some sand into the substrate to increase the permeability of the soil or fill an approximately 2 centimeter high layer of sand into the planting hole, on which the iris will later be placed will. Cut the roots of the irises back to about 6 centimeters in length and shorten the leaves to about 10 centimeters. Now the rhizomes or the iris bulbs are planted. The planting distance should be 25 to 40 centimeters. Place the rhizomes or Tubers flat in the ground so that about a third can still be seen. The irises need light to grow well. Fill the planting hole with soil and press it down well. Then supply the iris well with water.
Smaller iris species in particular are also very suitable as potted plants on the balcony or terrace. A peat-free potting soil, such as ours, is suitable as a substrate Plantura organic potting soil, optimal. Choose a suitable pot with a drainage hole so that excess water can drain off when watering and no waterlogging occurs. In addition, you can put potsherds on the bottom of the planter or work some sand into the soil.
When the irises are planted, the young plants must be watered regularly until they have grown well and established themselves in their location. You can find out what other care measures are necessary for magnificent iris flowers in our article on the iris read up.
