Irises need neutral or, in extreme cases, slightly acidic soil (pH 6.5 - 7.0).
Where is it better to plant irises in the shade or in the sun
It is very useful to know which flowers to plant in the shade.
This will save you time and prevent you from getting upset when the plant withers due to lack of light.
Pansies, forget-me-nots, lilies of the valley, irises and tobacco grow very well in shaded areas.
When and how to plant irises correctly
Iris bulbs are planted in open ground either at the end of April, as soon as the ground thaws, or at the end of September.
The soil temperature should not be lower than 12 degrees.
Plant the bulbs in an area well lit by the sun.
How fast do irises grow
Over time, irises grow in width, and the center of the bush gradually disappears.
Therefore, it is advisable to renew the plantings every five years.
You can divide an overgrown rhizome at almost any time, but it is still best to do this soon after flowering, since it is during this period that active root growth occurs.
Should irises be trimmed after flowering
This way the plant will develop organically.
All dried and damaged leaves should be cut off.
The final pruning of flowers is carried out closer to the cold weather: in late September - early October.
