Things to Consider

When you should apply the citrus fertilizer

From a general point of view, it is advisable to apply fertilizer to your plants once every one or two months when the plant is actively growing. When the tree is going through its dormant growth times you should apply the fertilizer once during a period of two to three months.

The tree grows actively during spring and summer and is dormant during fall and winter. The older the tree grows you can get away with not fertilizing it during the dormant season. For the active growth period, you can increase the time of application to two or three months.

You can also base the time frame for applying the fertilizer on the physical appearance of the tree.

Type of citrus tree

By now you must know that there are a variety of citrus trees that you can grow and you should understand when you have to plant them and when they get to blossom, this is some vital information that you should not ignore therefore do thorough research on that before planting them and choosing the fertilizer.

The type of fertilizer might also vary from the citrus tree you are planting. Fertilizers contain different nutrient levels that are manufactured to suit the different plants and to keep them from overfeeding, burning, or nutrient deficiency.

How you fertilize a citrus tree

There are two different methods to go about when it comes to fertilizing your citrus tree. The first option is the leaves and the second is the ground. Almost all fertilizer products provide you with instructions on how to apply it using whichever method provided. You are either supposed to spray the fertilizer on the leaves or spread it out on the area around the soil of the tree and not somewhere near the tree’s trunk.

The type of fertilizer your tree requires.

Every citrus tree is known to benefit from a fertilizer that has a rich and well balanced NPK ratio, a nitrogen-rich fertilizer, or a nitrogen source that meets its nutrient requirements. The fertilizer is also expected to have other micronutrients in it that include copper, iron, zinc, manganese, magnesium, and boron.

All of these micronutrients play a role in helping your citrus tree grow and yield the best results. Since citrus trees tend to prefer acidic soil then you can also use acidic fertilizer on the plants.
