Avocado Fertilizer Requirements

An avocado tree needs to be healthy, and that’s the job of a fertilizer. To produce healthy leaves as well as the fruits, the avocado tree must have healthy roots with minerals and water. Now, what are the minerals an avocado tree need?

  • Nitrogen
  • Phosphorus
  • Potassium
  • Calcium
  • Zinc
  • Boron
  • Magnesium
  • Iron
  • Sulfur
  • Maganese

Fertilizer provides different minerals in avocado trees – some are in high volume, and some are low. To talk about avocado, it requires a suitable amount of Phosphorus and Nitrogen to build a healthy metabolism, Calcium to build a strong structure, Zinc, and Potassium to produce fruit, Magnesium to enrich the photosynthesis cycle, and Manganese, Boron, and Iron to develop good health.

That’s all a fertilizer should provide.

Anyway, the avocados are strong enough to grow in hardy zones of USDA – 9b to 11, but as they mature, they’ll need more nutrition, and fertilizer should help them on the way.

But you can reduce the feeding by planting the tree in the proper place. A well-suited plantation process and adequate care can build a healthy tree. However, avocados have shallow roots while the feeder roots are at 6 inches top.

So, they should be placed in spring as the soil temperature is warm and protected from frost and wind.

Before you sow the seed, make sure to test the toil. It must have a ph of 7 or lower than that. If the result comes out as alkaline soil, tinker organic matter in the soil, for example, sphagnum moss. When you add at least 2-1/2 pounds or 1.1 kg of peat moss in a 1 square yard, the soil will have waned one unit.

How to Fertilize Avocados

In the very first year, the fertilization schedule can be divided into three sections. Once in summer, once in spring, and the other in fall. By the way, you have to cease feeding when the plants are dormant.

Usually, the time is in late autumn. Anyway, use one tablespoon of nitrogen for each plant and sprinkle it on the soil near the tree. Have a deep watering to let it go in the soil.

The fertilization will not be the same all the way. As the nutritional demand changes with time, you have to respond accordingly. For example, when the plants are in their 2nd year, increase nitrogen.

Increasing it up to 1/4 pound will do, which is divided into 3 times as the schedule. In the 3rd year, it will be 1/2 pound.

Gradually every year, increase nitrogen by 1/4 pounds. To ensure zinc, apply zinc once a year. The amount should be minimum. Other than that, no unique fertilization is required.

But, what you will have to do is, have a close eye on the plants as they will show symptoms if anything goes wrong or required. If you notice anything, take necessary actions. That should do just fine.

Are coffee grounds good for avocado trees?

We know nitrogen is the essential element for the proper growth of any plant. When it comes to the natural source, coffee grounds are great as a natural nitrogen source. Because of this, application of it to avocado trees can influence the growth of green and dark leaves at a large number.

But, too much of it can cause a reduction in fruiting. So, if your plants already have healthy leaves with no yellowish spots, that means they don’t need any nitrogen. And in this case, you also shouldn’t apply coffee grounds to your avocado trees. Apply it only if there is a deficiency.

Is Epsom salt good for avocado trees?

Epsom salt is rich in magnesium which avocado plants need to protect themselves from chlorosis. As the requirement is minimal in amount, you should not use more than necessary.

Are eggshells good for avocado trees?

Eggshell is on calcium carbonate. It is an essential nutrient for plants as it develops cell walls. This means, eggshells aka calcium carbonate, are also good for your avocado plants.

When to fertilize avocado trees in southern California?

If you are someone from southern California, your last nitrogen application should be before October 1. After that, from march, you can again start using nitrogen.

Is chicken manure good for avocado trees?

Avocado trees require zinc, phosphorus, and other nutrients along with nitrogen. In order to ensure all the nutrients for your plants, if you like single-use fertilizers, chicken manure is a good choice for you. Just apply it in February. Before applying, be sure that it is well composted.

Conclusion

The health benefits of avocado are genuinely beyond counts. For the abundant benefits, so many people are being attracted to having avocado plants in their garden. But, it’s imperative to secure appropriate fertilization for proper and healthy fruiting, and competent application of that fertilizer is also equally significant.
