Getting your Desert Citrus Ready for Summer

Temperatures are starting to warm up in the desert and it’s time to work on citrus trees once again. Generally, pruning can begin in February and March after the frost season is safely past.

Look for branches of the citrus tree that do not have any leaves and prune them off 1 inch away from the trunk using hand pruners. Also remove any limbs near the inside of the tree that are growing across other branches.

Never prune citrus in the middle of the summer to the extent that you expose the bark to sun. This will cause the bark to sunburn. If necessary, however, you can tree trunk paint to coat the trunk to prevent sunburn.
Foothills Ace offers some excellent tools to help in this process including:

  • The Ace By-Pass Lopper comes with a chrome blade and aluminum handles with cushion grip.
  • The folding tree pruning saw features a triple-cut blade for push-pull cutting. Includes a cushion grip and safety double lock.
  • Bypass pruners with cutting capacity of three-quarter inch. The pruners have a high carbon, heat-treated and tampered blade. Chrome-plated upper and lower blade with cast aluminum powder-coated handle.
  • Arizona’s Best tree trunk paint can be applied in April. This non-toxic tree trunk coating protects the tree’s trunk and or branches from the sun’s harmful rays. This paint is especially effective when applied prior to the warmer months of the year. Quart container comes in two colors: White or Go Natural brown.

There are also several citrus pests that are native to Arizona, and these can cause significant damage to crops if they are not carefully controlled. Examine the citrus tree once per week for signs of insect infestations and consider using Horticultural Oil for added insect protection for your trees and shrubs:

  • Ortho Volk Horticultural Oil Spray is for use during the growing season. This is an excellent product for fruit and shade trees. It controls scale insects, red spider mites and mealy bugs. It can also be used as an indoor plant polish. One quart makes 12 gallons for growing season spray or 6 gallons for dormant spray.
  • Summit Year-Round Horticulture Oil is a lightweight horticulture oil concentrate that kills and repels insects and prevents spread of diseases without use of dangerous chemicals. This product is formulated for year-round use. It is odor free and can be used on fruit, flowers, vegetables, ornamentals, trees and shrubs. One quart dilutes to 25 gallons of usable product. Kills whitefly, aphids, spider mites, mealy bug, scale mites, fungus gnats and more.
