How To Choose The Best Fertilizer For Citrus Trees In Containers?
Nitrogen-Rich
Out of the essential nutrients that citrus trees appreciate, nitrogen is the thing they need consistently during the entire growth, and the required amount will be more when they mature.
Make sure the fertilizer you choose for them should be nitrogen-rich. It’d be better if it includes both slow-release and fast-acting kinds of nitrogen. The fast-acting kind is to serve for instant nitrogen requirements of your plant while the slow-release one is for long-term feeding.
It is suitable for citrus trees in containers because extra watering might leach away the fast-acting nitrogen.
This kind, as the name implies, will slowly release the nutrient to provide to the soil and it can last up to one month before re-fertilizing. Therefore, there will be fewer feeding times while your citrus trees still have enough nutrients to thrive happily.
Other Nutrients
Different soil types will require different nutrient ratios and ingredients.
For healthy soils, a multi-purpose fertilizer is the best bet. Such as 10-10-10 NPK ratio models. For the soil with phosphate or potassium deficiency, you should choose a special fertilizer containing an ultra-high amount of these nutrients to nourish the soil.
Aside from nitrogen, phosphorus, and potassium, citrus trees need various trace minerals, such as manganese, zinc, and iron.

FAQs
When should I fertilize my potted lemon tree?

How often should you feed citrus trees in pots?
You should feed potted citrus trees every other month.
Can you over-fertilize citrus trees?
No, you can’t. Over-fertilizing a citrus tree equals that you’re killing it. The most common consequence of over-fertilizing is burnt roots or burnt leaves.
How do you fertilize a lime tree?
The right way to feed a lime tree is by fertilizing it every other month using a nitrogen-rich fertilizer or compost. Remember to provide it with good warmth and watering as well.
Why are lemon tree leaves turning yellow?
Lemon tree leaves are turning yellow with green veins, the main cause is an iron or zinc deficiency. If the leaves are a yellowish-green blotch at the leaf base that spreads outward, the plant is lacking magnesium.
If leaves of the whole lemon tree are turning yellow, it is a sign of lacking nitrogen or nutrients.
Conclusion
One fertilizer does not fit all the potted citrus trees’ needs. And, that explains why there are so many options in the market at different NPK ratios. It is important to figure out the nutritional requirements of the soil and the tree before going shopping.
