How Do You Fertilize Potted Lemon Tree?

Fertilizing helps ensure the stable and healthy development of your houseplant. However, not all gardeners provide their crop with what it wants. So, how do you fertilize a potted lemon tree?

There are three options for fertilizing a citrus houseplant: liquid, dry, and spike. Each approach comes with a different fertilizing method. The fertilizer you choose also affects the way you feed your plant.

Today, Swipe Garden will give you in-depth instructions about how to take care of your plant. Let’s read on to discover!

How Do You Fertilize A Potted Lemon Tree?

When fertilizing a potted citrus tree, you have three options: liquid, dry, or spikes. Each has advantages and disadvantages. The best way depends on the size, region, and environmental aspects of the plant.


Liquid fertilizer is easy to get by and is available in large enough quantities to last longer than other options. 

To apply the liquid fertilizer, please follow these steps:

  • Dilute the liquid with the instructions on the product’s label. The quantity of water varies in each product.
  • Apply the mixture to the soil. You can utilize a spray bottle for better dispersion. 
  • Don’t spray on the plant or the leaves. 


Dry fertilizer is a good choice since it is slow-release. Instead of contributing to the water content in the soil, it blends first and will gradually release its nutrients over time.

The method of using dry fertilizer is relatively straightforward:

  • Spread it over the topsoil, leaving some inches from the trunk.
  • Slightly toss the soil to blend with the fertilizer. 
  • Don’t dig too deep since your citrus tree may have shallow roots. 


Spikes are pre-measured. Hence, there’s no risk of over-fertilizing if you examine the pot size and apply the exact quantity.

This option appears to be the easiest method to apply to your plant. You need to insert the spike containers into the soil for a determined period. 

Remember to check the installation directions on the package for the exact quantity and attachment method.

Citrus thrives in average home temperatures. Most can endure short frost. 

However, you need to keep your citrus trees away from breezes as well as heating and cooling pipes. Containers of citrus may spend the summer outside, but you have to keep them indoors until the risk of frost has passed in the spring. 

To avoid overheating the tree trunk, make sure the plastic tube is white or lighter in color.

Then, transfer them slowly over several weeks to allow them to adapt. Otherwise, they may lose their growing fruit.
