  • Fertilize healthy trees. A simple calculation is based on trunk diameter – use one pound of a high nitrogen fertilizer (slow release type such as 19-5-9) per inch diameter of tree trunk. Spread the fertilizer evenly throughout under the drip zone of the tree.
  • Fertilize evergreen trees, such as live oak, at the rate of 1-3 pounds of nitrogen per 1,000 square feet of root area. One pound of nitrogen is equivalent to eight pounds of 13-13-13. Fertilize deciduous trees (oaks, cypress) at the rate of 3-6 pounds of nitrogen per 1,000 square feet.
  • Fertilize winter bedding plants such as pansies, snapdragons, calendulas, dianthus with a complete and balanced fertilizer at one pound per square feed of bed area. Wait at least another month to fertilize the lawn.
  • Ball moss is not a parasite on oak trees, but if you don’t like the looks of it, spray copper hydroxide (Kocide 101) this month.
