Trees gain from correct application of fertilizer to enrich the soil. Like other fruit-trees, citrus trees require the proper balance like copper, boron, manganese and magnesium for optimum fruit production and development. Check the soil to find out whether it’s strange nutrient imbalances before fertilizing.
As they age, trees will require fertilizer. In humid climates like Florida throughout the first-year, start applying fertilizer in the start of the period in February as reapply every six months through Oct, and the buds begin to swell. About 1/2 pound of 10-10-10 fertilizer per tree. Every seven months in the next year, use about 1 pound per tree. Every nine months for the year, use 2 lbs per tree. Every 1-2 months in the fourth-year use 3 lbs per tree.
For citrus trees that are older and 5 years old fertilize a time to 3 times with 5 lbs of 10-10-10 tree. Fertilize in November, May and February. For every application, use 1 pound of fertilizer for every year of the treeâs age. For instance, a Florida tree would get 10 lbs of 10-10-10 three individual programs for an overall total of 30 lbs per year.
Dry Environment Expanding
For citrus grown in climates like Arizona or California, the primary fertilizing ingredient needed for tree vigor is nitrogen. Most soils have potassium and phosphorous. Generally, donât use nitrogen fertilizer in the first-year. In the next year, use 1/2 cup of ammonium sulfate per tree every six months beginning in March. This fertilizer is 21% nitrogen. To TO AT LEAST ONE cup per tree per program, improve in the third-year. In the fourth-year use 2 cups per program, growing to 2 1/2 cups in the fifth through ninth years. Improve the ammonium sulfate to 4 cups per program for the life of the tree.
Spread the fertilizer evenly on the floor in a band over the fringe of of the citrus treeâs leaf canopy. Donât spread it near the trunk. Make the band as broad in toes as the tree h-AS years of age. Yearold example, you’d spread fertilizer on the bottom over the canopy fringe of of a 5 – yearold citrus tree in a band 5 feet Water the trees carefully after every application of fertilizer. This can be especially essential in dry climates.
