Time It Right
The best time to replace plants or pot up new containers is in early fall, when summer's heat has waned and night temperatures are inching toward the cooler side. Depending on where you garden, this means anywhere from late August to late October.
Replacing Plants
To swap out tired annuals, slip a hand-held trowel into soil around the base of a plant. Gently pry the plant from soil. Tuck new plants into holes created by removing existing plants. Add removed plants to the compost pile.
Great Fall Performers
Some plants segue from summer to fall without missing a blooming beat. Ornamental grasses, Dusty Miller, Narrow-Leaf Zinnia and Sedums fall into this group. Others, like Petunia or Coleus, perform strongly into autumn, as long as you trim stems back by a third in late summer and fertilize to stimulate new growth.
