Southwestern Deserts  September, 2000 Regional Report  Improve
Soil in Garden Beds  To get the garden ready for fall crops, add
organic matter, digging a 4- to 6-inch layer of compost into the
soil to a depth of 12 to 18 inches, add fertilizer containing
nitrogen and phosphorous (desert soils have plenty of
potassium), and add soil sulfur (3 pounds per 100 square feet)
to enhance drainage and reduce alkalinity.  Plant Cacti and
Succulents  Propagate jointed cacti such as prickly pears and
chollas by cutting them with a clean, sharp knife at the joint.
Separate aloe and agave "pups" from their parents, retaining as
much root as possible. Allow the open cuts to callus for a week
before transplanting into well-drained soil. Their roots will
rot if kept too wet.  Fall Plant Selection  Late September and
October are prime planting months in the desert. Decide what
types of plants you want in your landscape, what cultural
requirements they have, and what conditions your landscape
provides. Look through plant books
