Best Fertilizers for Avocado Trees

For a plant food that is organic and environmentally friendly, Down to Earth Organic Citrus Fertilizer Mix is a perfect choice. This fertilizer mix contains natural ingredients, so there are no artificial growth stimulants or toxic chemicals. Best of all, the mix is specifically crafted to nourish fruit trees. Avocado trees will flourish when treated with this fertilizer mix. Gardeners will find that their trees are healthier all around, with stronger limbs and root systems and fuller foliage. Avocado trees that have been treated with Down to Earth fertilizer also often produce larger fruit.

Earthpods are a simple, effective way for gardeners to ensure that essential nutrients are delivered right to their avocado trees. These pods are pre-measured and contain a balanced ratio of nutrients, minerals, humic acids, microbes, and natural growth hormones that fruit trees thrive on. EarthPods Premium Fruit & Citrus Plant Food, which have no smell, can be easily inserted into the soil. The pods will then break down after watering and begin to release a slow, steady supply of nutrients. In addition, because the pods work to directly nourish the roots, trees treated with this plant food are stronger and healthier, with lush, deep green foliage and larger, tastier fruit.

J R Peters Citrus Food Fertilizer is crafted with a balanced mix of nutrients that will help avocado trees thrive. This fertilizer is designed to nourish trees in two ways. It absorbs into both the leaves and the roots. This creates stronger root systems, which leads to healthier trees. It also helps foliage become thicker, with a richer color. The fertilizer can also help to treat plants that have been damaged by drought or neglect. J R Peters Citrus Food Fertilizer can help plants produce larger, more abundant, and more flavorful fruits.

Jobe’s Organic Fruit & Citrus Tree Fertilizer Spikes are simple to use and will greatly reduce the mess gardeners often face when using fertilizer.

The fertilizer is inserted near the plant’s base and is then directed straight towards the plant’s roots. Avocado trees that have been treated with these fertilizer spikes are fuller and healthier and will produce more abundant fruit.

Epsoma Citrus-tone Plant Food features a balance of nutrients that are specifically designed to boost the health of fruit trees.

Raising a Healthy Avocado Tree

Don’t you wish you could have the pleasure if eating a delicious, nutritious avocado that you grew by yourself? Growing an avocado tree is a fun hobby that results in a tasty reward. With proper care, growing an avocado tree is not difficult.

Avocado trees are tropical plants and they do not tolerate cold very well. Their tree limbs are easily susceptible to damage from wind. As such make sure to grow it in a warm and sunny climate OR give it the proper conditions to grow if you are in a cooler climate.

Planting Your Tree to Maximize Sun and Warmth

Make sure to plant your avocado tree in a place where it receives at least 6 hours of direct sunlight per day to maximize fruiting (if possible aim for 8 hours of direct sun light). If you are in a cooler climate, you can consider planting in a pot near a wall that receives plenty of light. The point of planting it near the wall is to let some of the heat from the sun radiate onto the tree to keep it warm. As for the pot, you may need to consider bringing in the avocado tree during winter months if you live in a colder climates. Bring in the tree once temperatures drop below 50 degrees (if you do this, it would be prudent to supplement with a grow light).

Well-Draining Soil

Make sure to plant your avocado tree in soil that drains well. Avocado roots need good airflow to minimize the risk of root disease. Always let the soil and/or container dry out before deep watering so that the entire root zone is moist. Unfortunately, avocado trees have shallow roots, which make them prone to water stress as the top soil tends to dry much faster than deeper soil. Mature avocados trees need water equal to about 2 inches of rain fall each week during the summer. Younger trees will need watering at least 2-3 times per week. If you live in a hot climate, which will dry out the soil fast, you may need to water even more frequently than that.

Best Fertilizers for Avocado Trees

Ideal N-P-K Ratio

Avocado trees flourish well with fertilizers that are often used for citrus trees. Aim for an N-P-K ratio of about 2-1-1 is ideal. Avocado trees need plenty of nitrogen to flourish. For this reason, also try to keep your avocado tree away from lawn, if possible, as the competition for nutrients may leave the avocado tree with deficiencies.

You will want to fertilize your avocado tree roughly 3 times in the first year (fertilize in the spring, summer, and fall). In late fall, the tree will become dormant and you should not fertilize for a fourth time. Make sure not to over fertilize because this can be just as harmful to your avocado tree.

Bottom Line

Again, I recommend buying the Down to Earth Fertilizer​. Don’t make the mistake of buy any average fertilizer at your local gardening store. Many of them will simply not produce the same results. You cannot go wrong with any of the fertilizers above.
