Good article!
In the part about hardy mums and florist mums, you could mention that mums (like many perennials) are best planted in the spring. Hardy mums planted in the fall often do not survive the winter. The mulch you mentioned would help improve survival. If planted in the spring they do not need mulch. Also, they will best survive the winter if you leave stems on until spring.

santi rodriguez, "Mums fair exceptionally well in full sun;" I believe you meant to say 'fare'. The piece is well written and informative. Thanks.
