9. Review Feeding and Mulching Needs Before Peak Growth Begins
As irises prepare to enter their peak growth phase, it’s important to ensure they have the nutrients they need. Apply a balanced, slow-release fertilizer around your plants, but be careful not to over-fertilize, as this can lead to lush foliage with fewer blooms.
Consider applying a thin layer of mulch to conserve moisture and regulate soil temperature, taking care to keep it away from the rhizomes. Providing the right nutrients and mulching appropriately will support robust growth and a stunning floral display in the months to come.
