Growing Butterfly Bush Mix Seeds
Plant Butterfly Bush Seeds: Sow seed in cell packs or flats, press into soil but do not cover. Needs light to germinate. Kept at 70-80°F., germination is spread out over a period of 1-5 weeks. Transfer into 3 in. pots as soon as seedlings are large enough to handle. Once the plants become well rooted, transplant into the garden 6 ft. apart. See Starting Seeds for information about growing butterfly bush and other seedlings under lights.
Grow Butterfly Bush: Butterfly bush plants flower on new growth, cut plants back to 6-12 in. tall in early spring before new growth begins to increase flowering and control size.
