It's time to divide and plant bulbs and perennials. Division controls the size of the plants, rejuvenates them for prolific blooming and increases their number.
During the summer months ginger has produced abundance of growth. Dig up and divide rhizomes of this perennial. Shell ginger (Alpinia zerumbet), right, is a vigorous grower that produces magnificent pinkish, shell-shaped flowers looking much like a cluster of grapes. Propagation is easy. Dig up a rhizome and cut it, leaving an immature sprout or two on each section. The rhizomes should be planted only about 2 to 3 inches deep. The gingers require little care other than moist soil, afternoon shade and occasional fertilization.
Next week: Daylilies, stokes aster and digging bulbs.
. Pruning bougainvillea should be done before the middle of September to ensure good blooms this winter. And now's the last chance to prune your poinsettia. The rule of thumb is not to prune after Labor Day.
