Newly Planted Citrus:

  • When planting your new citrus tree, dig a hole twice as wide and the same depth as the root ball. 

  • Replace 1/3 of the native soil with compost, peat moss, or organic planting mix.

  • Mix 1 cup of Espoma Citrus-tone into the amended soil.

  • In the center of the hole create a small cone of soil and place the tree on this mound. Allow the loosened roots to fan out over the mound. 

  • Use the blended soil to backfill the hole around your citrus tree. Gently tamp the soil down to remove air pockets. 

  • Be sure that the top of the root ball is at or slightly above the existing soil line for best results. 

  • Water deeply after planting.

Established Plants: 

Established plants should be fed in late winter, late spring, and early fall.

Apply Espoma Citrus Tone around the dripline or your tree (where the outer branches of the canopy are) and mix into the soil. Plant food should not be applied within 6 inches of the trunk of larger trees. Water thoroughly after each application.
