Fall may be the best time to set out perennials so they can settle in during the cooler winter months, but May is when most nurseries tempt you with great selections of blooming plants in gallon containers. Don't resist: it's okay to indulge in a little instant gratification. In all but the hottest desert areas, gardeners can still plant perennials this month.
When you shop, buy plants that will deliver the longest show for your money, with minimal fuss.

* Before planting, soak the rootballs by immersing nursery cans up to the rims in a water-filled sink or tub as long as overnight.
* Amend the soil in the planting hole with organic matter such as compost to improve water retention.
* If roots are tightly coiled, gently pry them apart with your hands or use a sharp knife to score the root mass.
* After planting, spread a 2- to 3-inch layer of mulch such as compost around plants to keep roots cool and soil moist. Keep mulch off crown of plant.
* Be prepared to water plants as often as twice a day until their roots get established.
* About two weeks after planting, begin regular feeding with a gentle liquid fertilizer such as fish emulsion.
* Clip faded blooms regularly. Shear off spent blossoms of ground-hugging plants, such as catmint, diascia, Santa Barbara daisy, and verbena, when 80 percent of the flowers have faded. Pinch or snip off blossoms of blanket flower and pincushion flower one at a time. On penstemon, cut the entire stalk down to the base of the plant.
