October “In The Grow”

Q. What do I focus on now in my flower gardens? Should I be pruning things before winter? Do I need to clean up the perennials and maybe put down some mulch? What do I do to get a couple of rose bushes ready for winter? – Mike Wadsworth West Lafayette, Ind. A. Autumn frosts will soon take their toll on the garden.

Winter aconite is appropriately named for its early arrival, often pushing its blossoms through a cover of snow in February, though sometimes as early as January and as late as March. Plants…Read more about Lesser Known Perennials Extend Spring Color Show[Read More]
