Selecting A Fertilizer For Citrus Trees

Unless you are a commercial citrus grower, you most likely have one or two different types of citrus trees. For those people in the more northern areas, the trees are probably in large pots and you transfer them inside in the colder months and to the outside in the warmer spring through fall times of the year.

Most of the citrus trees grown in pots and moved indoors or outdoors are dwarf varieties. These trees can produce an amazing number of lemons, limes, oranges, grapefruit and even mangos and avocados, all which benefit from the same fertilizer for citrus trees.

What Citrus Trees Need

Most varieties of citrus trees will need to be fed three times a year. This will include once in the late spring when they are becoming active, once in the late summer and then again in the winter.

For a simple way to remember just think of three holidays. Plan to provide a good feeding of specialized fertilizer for citrus trees on Valentine’s Day (winter), Memorial Day (spring) and Labor Day (late summer). You may need to make slight adjustments based on your zone.

Just like any other type of living thing, citrus trees need both macronutrients and micronutrients. The macronutrients are the big things that the trees need for health and survival. These include nitrogen, potassium and phosphorus.

The micronutrients are found in smaller amounts in fertilizer for citrus trees. They include manganese, iron and zinc. Your potting soil or natural soil will include these micro and macronutrients, but they will be used up by the tree and need to be replaced on a regular basis.

Signs of Trouble

The age, production and the overall health of the trees will come into factor when determining the correct amount of fertilizer to use. Typically, when mature leaves start to yellow in the growing season it is a sign of depleted nitrogen levels in the soil. New leaves that appear light green with dark green veins are often caused by manganese or iron deficiencies.

Best Options

One of the best options to apply regular fertilizer for citrus trees is through the use of granular formulations. These are easy to measure and can be sprinkled on the soil around the tree and then ranked into the top few inches of the soil.

To help the tree to utilize the fertilizer, make sure to water before and after application. Follow the directions on the fertilizer and double check before applying to ensure you do not over fertilize.
