Irises are grateful flowering plants in the garden, as they hardly need any special care and attention once the location has been chosen correctly. You should only dig up, divide and replant the rhizomes every few years, otherwise the plants can become lazy due to a lack of nutrients.
Irises are undemanding garden plants
Basic site conditions for irises
Overall, irises are relatively undemanding plants that can grow in very poor soil without special fertilization. Irises usually thrive particularly well in full sun. Within the family of irises, a distinction is made between:
- Marsh irises
- Steppe irises
- beard iris
Position different types of irises correctly
The bearded iris (Iris barbata hybrids) with their eye-catching flowers can be planted relatively flexibly in most locations in the garden. You can either grow the young plants you need from seeds yourself or propagate them by dividing the rhizome. While swamp irises such as the species Iris pseudacorus can also grow well in permanently wet locations, the soil for steppe irises such as Iris variegata should be as dry as possible.
tips and tricks
Iris species with a preference for dry soil should be planted in soil that is as permeable as possible. If the soil is heavy, you can use a drainage layer of compost or coarse sand to prevent waterlogging.
