SEASONAL CARE

Spring Care:

Flowers mostly in sprays along one-year-old or two-year-old branches. Cut off spent flowering branches immediately after flowering. This will help to produce the maximum amount of vigorous flowering wood.

Summer Care:

Prune diseased, dead, damaged; deadhead

Fall Care:

Winter Care:

Flowers on new wood, so prune in late winter to early spring if needed

Long Term Care:

Insect Pests:

Aphid, Snapdragon Plume Moth, Spider Mite

Wildlife Pests:

Diseases:

Spiraea powdery mildew

Environmental Problems:

Can be aggressive self-seeders, and have escaped gardens and naturalized in many areas of the eastern U.S. Plants will also spread in the garden by suckering.
