How to Plant AGERATUM Seeds

Sow seeds in cell packs or flats, press into soil but do not cover. Needs light to germinate. Kept at 75° F., germination is in 5-14 days. Can direct sow after all danger of frost in groups of 3-4 seeds spaced 6-12 inches apart. Thin to the strongest plant.

Comments: Full sun in cooler climates, part shade elsewhere. Prefers rich, moist soil. Blooms are extraordinarily long-lived, dead heading is necessary, yet infrequent. Plants are low maintenance, resist rabbits and deer. Flowers attract bees and butterflies.
