Prune Iris Leaves in Autumn for Healthier Blooms
Autumn is the ideal season to prune iris leaves, ensuring their health and promoting successful blooming. This task, when done correctly, supports the development of rhizomes and young shoots, reduces the risk of rot, and maintains the natural structure of the plant.
Proper pruning involves cutting iris leaves diagonally or in a fan shape, not straight across. This technique exposes the rhizomes and young shoots to sunlight and air, promoting their growth and reducing the risk of rot by facilitating quick drying after rainfall. The fan shape also ensures better ventilation, preventing water accumulation, and reducing the risk of root and base rot.
Improper pruning can have detrimental effects. It can lead to decaying tissue, attracting harmful microorganisms, fungi, and pests like slugs and snails. To avoid this, it's recommended to cut the leaves at a height of about 10-15 cm from the base, removing completely dry and diseased parts. This practice keeps irises strong and decorative, simplifies spring work like fertilization and soil tilling, and protects against winter precipitation and snow damage.
