How Do You Put Fertilizer On An Avocado Tree?

Typically, you must fertilize the avocados three times a year – fall, summer, and spring. While the tree enters dormancy in autumn, you can stop fertilizing. Ideally, 1 tbsp nitrogen broadcast onto the soil surrounding the tree can suffice.


Once you finish throwing in the necessary fertilizer, you can water deeply. It helps the fertilizer seep into the soil. When the tree matures, its fertilizing needs change.


Of course, the plant still needs nitrogen, but you need to increase the nitrogen ratio from the second year onwards. 1/4 pound nitrogen spread over three applications can do the trick for the plant.


You need to increase the nitrogen content in the third year to ½ pound, spread over three applications. Now, from every year onwards, you need to increase the nitrogen content by ¼ pound spread over three applications. Any fertilizer over this will only overfeed the plant and is unnecessary.


If your soil is heavily alkaline, you can add peat moss into it to regulate peat moss. But it will happen over time. Hence, you can also supplement it using chelated iron.


In addition, inspect for iron deficiency in the form of new leaves showing yellow margins and green veins. Beyond that, the avocado tree needs no special fertilizing. You can go with a general-use fertilizer to meet its needs.


However, if the fertilizer employed does not have zinc, consider feeding some zinc to the plant, but it should not be more than once in 12 months.


At all times, you must inspect the plant for distress signs or infestation by pests or diseases and take remedial actions instantly. If you fertilize well, you can relish your favorite guacamole in a few years.

In winter, the plant enters dormancy. Hence, avoid fertilization. But, mulching can be beneficial during the winters as that amplifies the soil nutrients and offers an insulation layer against frost.


Is Iron Deficiency A Major Concern In Avocados?

Avocados require the correct mineral balance because the percentage of every mineral in the seeds, flesh, flowers, and leaves is variable. Hence, there is a greater need for some minerals than others.


The plant needs phosphorous and nitrogen for healthy metabolism, zinc and potassium for its fruit, magnesium for better photosynthesis activity, manganese, iron, and boron to maintain good health, and calcium for the overall structure.


Hence, if there is any deficiency, it will show. So, if you do not include iron in your fertilizers, it will result in the plant’s poor health and make it susceptible to diseases. Make sure to go for complete avocado care.
