Our Top Choices

At A Glance

Here are our most recommended products. Make sure to keep reading below to find individual descriptions of each of them.

What’s So Important About Proper Nutrients?

Raising a citrus tree is not difficult, but it does take a lot of time. It takes time, patience, and the right gardening tools. 

Citrus trees generally do not bear fruit until they are at least 3 years old. You will want to properly water and fertilize your tree so that it is healthy and has the maximal chance of bearing fruit during the growing season. 

This broad category includes a whole range of different trees including lemon, orange, lime, and grapefruit trees.

Without the right nutrients, your tree may not bear fruit. And even if it does bear fruit, it might not be as sweet as it could be.

Choosing the right product can be difficult because there is so much marketing hype on labelling these days. Some products make false claims, which are hard to verify because you will not notice the downstream effects of the fertilizer you choose until months later. 

Different products are composed of different ingredients and also contain different N-P-K ratios. The ones listed below are the ones that we recommend.

How to Raise Healthy and Fruitful Trees​

Love the idea of growing your own produce and raising your own citrus tree? A squeeze of lime in a soda or a freshly peeled orange truly kickstart the morning and help to make life more interesting.

With the right climate, planning, and fertilization, you will be able to raise your own tree and create your own zesty fresh fruits.

They are some of the easiest fruit trees to grow in your own backyard.

Plant in an Area with Plenty of Sun

Citrus trees are subtropical trees, and as such, they love sunshine. At least six hours of direct sun (preferably 8 hours) is recommended for maximum fruiting.

They also grow better in warm areas, so if you are growing it in a slightly cooler climate, plant it near a wall that receives plenty of sun can be helpful as the heat that radiates off the wall will help to keep the plant warm. If you are raising your tree in a very cold climate then you will want to make to raise it in a pot so you can bring it indoors during the winter – make sure that your tree does not sit in freezing conditions.

Well-Draining Soil

Make sure that the soil that you plant in is well-draining. If water is left to pool in the root zone, your roots will quickly develop diseases that will greatly set you back.

One way you can check this is to dig a hole as if you were going to start planting and fill it with water. If the water does not drain in half an hour, then you will want to find a new place to plant your tree as this soil does not drain fast enough.

Watering Schedule

When you first plant your tree, you will want to regularly water your plant. Wait to make sure the soil is dried before watering again. As your tree ages, you will want less frequent watering, but make sure when you do water, it is deep watering so it penetrates into all the deeper root levels.

Be careful not to overwater as this tends to be the most common mistake of new owners. If your trees’ leaves are yellowing it may indicate either lack of fertilizer OR overwater (amongst other issues such as pest infestation).

Fertilization and N-P-K Ratio

Fertilize roughly every 3-4 months. Apply the fertilizer around the tree and not simply next to the trunk as most of the roots will grow farther away from the trunk. Slow release nutrients work well.

Ideally, a product with an N-P-K ratio of about 2-1-1 or 3-1-1 is preferred. They rely on the high nitrogen content to flourish.


Citrus trees do not rely on pruning to fruit well. That being said, you will want to prune the tree when it is immature to open up the center of the tree (to encourage air flow and more sunlight to hit all areas of the tree) and also to create a sort of bushiness so that it grow wide rather than tall. If possible, try to prune your tree so that there are about four main branches.

You can check the Arizona Cooperative Extension for tips on pruning.
