The way to Fertilize Citrus Container Plants

Potted citrus trees look their best and produce the very best fruit when you fertilize them properly. There are two approaches you can take to fertilizing your tree. You can use a slow-release fertilizer annually or a liquid fertilizer on a set schedule. While the first method is simpler, the second gives you more control over the quantity of fertilizer your tree receives within time. Citrus trees also need micronutrients and you can ascertain the need by the look of the leaves.

Fertilize a potted citrus tree with a slow-release fertilizer annually in early spring. A fertilizer labeled specifically for citrus is the best alternative. If a citrus fertilizer is not accessible, use a fertilizer with twice as much sulfur as phosphorous and potassium, like 12-6-6. The fertilizer should also include micronutrients, particularly iron, manganese and zinc.

Fertilize your citrus tree every other week with a fluid or water-soluble fertilizer rather than utilizing a slow-release, if preferred. Begin fertilizing in early spring and then stop at midsummer to allow your tree a opportunity to slow its increase in preparation for winter.

Water a potted citrus once the potting medium is dry at a depth of 6 inches by filling the pot with water till it runs out of the drainage holes at the bottom of the pot a couple of times per week. For large trees kept outdoors, water each day from the hottest aspect of summer. Improper watering triggers leaf symptoms very similar to those of a tree that needs micronutrients, so suitable watering enables you to eliminate improper watering as the origin of the signs.

Watch for signs of micronutrient deficiencies — leaves that yellowish while the veins remain green — and also implement micronutrients as vital. Correct the problem by spraying the leaves with fish emulsion.
