Basic site conditions for irises
All in all, irises are relatively undemanding plants that can grow even in very poor soils without special fertilization. Irises usually do particularly well in full sun. Within the iris family one differentiates between:
- Swamp irises
- Steppe irises
- Beard iris
Position different types of irises correctly
The bearded iris (Iris barbata hybrids) with its striking flowers can be planted relatively flexibly in most locations in the garden. You can either grow the necessary young plants from seeds yourself or multiply them by dividing the rhizome. While swamp irises such as Iris pseudacorus can also grow well in permanently moist locations, the soil of steppe irises such as Iris variegata should be as dry as possible.
Tips & Tricks
Iris species with a preference for dry soils should be planted in soil that is as permeable as possible. In the case of heavy soils, you can make do with a drainage layer of compost or coarse sand to prevent waterlogging.
