What is the best time to fertilize trees?

What should be ideal NPK ratio in fertilizers?
Studies have found that the ideal NPK fertilizer ratio of those nutrients for flowering plants is 3-1-2. (That’s 3% Nitrogen, 1% phosphorus & 2% potassium.) So look for that ratio on the label of packaged fertilizers; anything close to a 3-1-2, a 6-2-4 or a 9-3-6 should be ideal.

How are key lime trees adapted to Florida Keys?
The Key lime is well adapted to a variety of soils. Seedling and air-layer-propagated trees are well suited to the rocky, calcareous soils of the Florida Keys and extreme southern Miami-Dade County. However, salt damage from salt water intrusion and or wind-blown sea-salt is a frequent problem for trees in the Keys.
