• You should schedule citrus and frost-sensitive plant pruning after February 15, the average last day of frost in Phoenix. Pruning can be done through the end of March. This timing starts after the danger of frost damage but before citrus blossoms set for next season’s harvest. February/March pruning also allows the new growth following pruning to “harden off” before high temperatures arrive.:http://ag.arizona.edu/maricopa/garden/html/weather/frost.htm.
  • Although light pruning can be done year-round on deciduous trees, early February is the last month for heavier crown reduction and thinning.
  • Now is the time to put down the first of four applications of citrus fertilizer (Feb/May/Aug/Oct).
