When to Fertilize Citrus Trees
Fertilizing a citrus tree is the best thing you can ever do to help the fruits thrive and produce healthy fruits. However, you cannot fertilize this tree at any time. Instead, there’s a specific time to do it. So, when to fertilize citrus trees? It all depends if you are planting indoors or outdoors.
Typically, growing citrus indoors is not an easy task. It requires a bit of care, but it is worth it. Only fertilize citrus trees during the growing season, from late March to early august. Use liquid fertilizers such as kelp, seaweed, or organic granular fertilizer.
Do this every two to three weeks, but not in the Winter, since there’s new growth. Alternatively, use a small amount of organic granular fertilizer in late March to encourage new growth.
If you are planting your citrus trees outside, fertilize in early spring before the trees bloom. Generally, fertilize citrus trees every 1 to 2 months during the growing season. Then, increase the duration to every 2 to 3 months during fall and Winter.
Again, fertilize newly planted citrus trees only when they’re a year old. Also, fertilize older citrus trees once every three months. Don’t fertilize until the fruit is about the size of a pea, usually around mid-May.
Now that you know the right time to fertilize your plant, how to fertilize your citrus trees?
How to Fertilize Citrus Trees
Before fertilizing your citrus trees, you need to know that it doesn’t apply to new ones. Give them time, and feed them for at least one year. After that, you are free to fertilize your genius plants. Here’s how to.

- Check the label and follow the directions.
- Ensure that you don’t apply all of it at once – divide by three the annual amount of fertilizer needed by your tree. This act is essential because smaller trees require less fertilizer than larger ones.

- Remember the direction on the label; apply the right amount because too much nitrogen in the fertilizer leads to peeling.

Your Citrus Fertilizer Shopping Guide
Before purchasing your citrus fertilizer, you need to consider some vital aspects. Among them are form, desired effect, and chemical fertilizer content. Considering these factors will land you the best fertilizer for the citrus tree.
Organic vs. Inorganic
The first aspect to consider is checking the fertilizer type. For example, lemon tree fertilizer can either be organic or inorganic. Organic fertilizer comes from organic sources, such as organic compost, cattle manures, poultry droppings, or domestic sewage.
On the other hand, inorganic fertilizers are fully artificial and manufactured in exact doses. You can find their nutrient content on the bag. You can also find the one that meets specific needs.
Chemical Fertilizer Content
Apart from organic and inorganic fertilizer, check on the chemical fertilizer content. Chemical fertilizer is the number of synthetic compound substances formulated to increase crop yield. Chemical fertilizers show quick results and are easy to apply.
Too much of it can burn the plant and cause death. So, you need to check the exact content. For more details, check the back of the package or bag.
Another important thing to consider is form. Different citrus tree fertilizers come in different forms. This type of fertilizer comes in three primary forms: liquid, granular, and spike. Each Form has advantages and disadvantages. Let’s take a look at each.
These are solutions that boost the plant’s growth rate. They can either be a ready-to-use solution or a concentrated solution. For liquid citrus fertilizer to work, you should dilute it in water. Roots quickly absorb liquid fertilizers, and you can spray them on leaves.
This fertilizer looks like pellets or grains when you sprinkle it on the soil. They will dissolve slowly and offer trees a long-term supply of nutrients that can last an entire growing season or longer.
Spikes gradually dissolve in the soil, offering long-term feeding. Spikes are more costly than liquid and granular fertilizers, thus suited to those with just a few trees or potted trees.
To apply fertilizer, you need to check up on the growing stage. Citrus trees require fertilizer. Based on their age and soil nutrient content. Therefore, it is wise to test the soil with a qualified fruit tree specialist to determine exact nutrient needs.
Generally, use just one-third of the recommended fertilizer on the package for each feeding. For lemons and limes, conduct the third feeding until August or September. Don’t fertilize newly planted citrus trees until they’re two years old. Then, just water regularly to ensure they become established.
Lastly, check on the desired effect. For better root development and healthy foliage, citrus trees require fertilizer to help them bloom. A fertilizer that’s high in phosphorus enhances bloom production. Test the soil, and then select a fertilizer with an NPK analysis that suits the individual tree’s nutritional needs. This will help maintain the overall health of the citrus tree.
Reviewing the Best Citrus Tree Fertilizer on the Market
The best citrus fertilizer should contain high-quality ingredients. However, fertilizers come in different features, and in most cases, they vary in aspects such as NPK analysis. The best citrus tree fertilizer contains nutrients needed to correct soil deficiencies and create an optimal environment for the tree to thrive—the following types of fertilizer display such features.

Common Pests and Diseases Affecting Citrus Trees
There’s much to love about citrus fruits, including the pleasant taste. And up to now, it’s clear that you have the right fertilizer for your citrus trees. But when pests and diseases show up, things might go south. The trees might suffer and even die. However, you can get them back on track. So, here are the common pests and diseases and the best treatment method.
Citrus aphids usually suck the sap and can cause massive distortion if not controlled. Besides destroying fresh leaves and stems, they secrete honeydew, which attracts ants and may cause sooty mold. To prevent this issue, spray populations with Defender Pyrethrum.
Like aphids, citrus fruity is increasingly becoming popular. Since they like warmer humid areas, they will lay eggs in fruits as they ripen. So it is vital to collect and dispose of citrus fruit, including those that have fallen to the ground. To control them, yellow sticky traps and liquid lure traps entice fruit flies.
Citrus Gall Wasp
When you find eggs under the bark on the soft, new shoots of most types of citrus trees, be sure that it is a citrus gall wasp. The woody galls form around the larvae when they hatch from the eggs. The larvae develop within the galls, and the adults emerge through small holes in spring to go on to infect more shoots.
Therefore, galls in Winter encourage new growth in early to mid-Spring, just as adult wasps are looking for soft shoots to lay their eggs. To treat this disease, use a sharp knife or potato peeler to slice through as many galls as possible, and kill the larvae. Then, dispose of all material by wrapping in plastic and placing it in the garbage bin.
This mold grows on the sticky honeydew secretions of insects such as aphids. The good news is that the pests and the mold will disappear without treatment.
This disease occurs around the graft union of the plant, a point of weakness where fungal infections can occur. Treat it with a fungicidal poultice.
Scales are generally found on the undersides of leaves and soft growth. You see a shell-like covering (the scale) over a small, sap-sucking insect. Sapsuckers in large populations can cause massive destruction. Just remove it with a thumbnail, but the best control is with a horticultural, pest, or eco oil to smoothen the pest.
Closing the list is citrus leafminer. It tunnels through leaves under the outer skin, causing distorted and curly leaves. The pest, present from around the end of December through to April, is a small nocturnal moth that lays eggs on the undersides of soft new leaves.
These hatch into tiny grubs that burrow into and then move through the leaves. Apply horticultural pest or eco oil every three weeks to control the pest.
