Planting and Care
Butterfly weed does well in dry, infertile soil.
Because of its deep taproot, dividing is not recommended.
Wait until spring to cut plants back.
Be patient, plants are slow to emerge in the spring.
In colder zones, apply a winter mulch to prevent frost heaving.
Rot in poorly drained soils, rust, leaf spots
