Perennial Plant Care: A Source-Linked Record System

Keep one record per perennial with its name, location, bloom window, observed condition, cleanup decision, and division history. Divide based on the plant's condition and species guidance, not a universal calendar. University of Minnesota Extension recommends dividing when a plant is not flowering; fall-blooming perennials are generally divided in spring, while spring- and early-summer bloomers can be divided in fall.
