The Best Fertilizer for the Unique Meyer Lemon Tree

Last Updated on January 26, 2022 by Cinthia

Like many other citrus trees, the Meyer lemon requires a specific type of fertilizer to remain healthy and strong. This is especially true if you decide to grow your tree in an enclosed container rather than outdoors since the roots will not be picking up the natural nutrients from the soil and the surrounding environment.

The Meyer lemon is rapidly growing in popularity but is not a naturally occurring fruit. It was developed in China by cross-cultivating a lemon with a mandarin or pomelo, creating a new fruit that combines the taste and nutritional benefits of the lemon and orange. These trees can grow between 6 and 20 ft. tall and have dark, shiny leaves. Before the fruit develops, the tree will be covered in white blooms with purple bases.

Because the Meyer lemon is citric and unique, it is essential to choose the right fertilizer. This guide will identify some of the best options currently on the market, as well as what you should look for when visiting the store.

What to Look for in Citrus Fertilizer

Citrus trees are considered heavy eaters in the gardening world. They require a significant amount of nutrients to produce their fruits, whether it be lemons, oranges, limes, or similar delectables. When searching for the best fertilizer to put on your Meyer lemon tree, you want to pay close attention to the pH, make sure there is plenty of nitrogen, and see if you can get a formula that is slow releasing and easy to apply.

Pay Attention to pH

Perhaps it shouldn’t be surprising, but citrus trees actually enjoy having an acidic environment. Although this acid doesn’t get absorbed into the Meyer lemons themselves, a tree will grow healthy and strong if the soil its roots are embedded in is slightly more acidic and not basic. Acidic pH levels are anything under 7, while a basic level is anything above. The majority of fertilizers will list the pH on the container, so check out the label before purchase.

If you find a fertilizer that does not list a pH, then you can assume that it is neutral and does not lean one way or another. Neutral fertilizers will still be beneficial for your tree but won’t have the same benefits as a truly acidic formulation. 


Nitrogen is the most significant mineral for the majority of citrus plants, and the Meyer lemon tree is no exception. These trees require nitrogen to be able to grow healthy and strong branches, leaves, and delicious lemons. To maintain a healthy and viable output of fruit, even if you have planted your tree outside, it is important to spread regular nitrogen boosting fertilizer around the roots of your tree. If you don’t, then the Meyer lemon can suffer from mineral deficiency and will struggle to grow.

For this reason, the ideal citrus fertilizer will contain extra nitrogen rather than more potassium or phosphorus to create a healthy plant. However, you still need to make sure there are plenty of these other nutrients as well if you want your lemons to grow. 

Slow Release

The Meyer lemon tree is a type that grows best when it is allowed to flourish in containers. This means the ideal fertilizer will be slow-releasing, emitting nutrients over a period of time so the soil does not become flooded with unnecessary nutrients. When inside a container, it is important to give the lemon tree regular feedings and to replace fertilizer as frequently as stated on the container. If the tree is not doing well, make sure you are keeping the citrus in the right environment and meeting all of the soil requirements. You can then consider adding fertilizer or switching to a different variety.
