Citrus trees are fruit trees. However, they are not citrus trees. Citrus species, especially lemon trees, thrive in humid tropical and subtropical climates. That is, the fruit is the tree’s seed-bearing portion, which is generally delicious, colourful, and aromatic. After fertilization, it is generated from a floral ovary. Plants with deeper roots should be avoided when planting near citrus trees since they can compete with and potentially damage the shallow citrus tree roots.

In this article, we will show you the Best Citrus fertilizers, so without wasting time, look at the list and buy what you like most.

So, let’s start with the question: What should be considered before buying a Fertilizer for Citrus?

All citrus plants require a balanced N-P-K fertilizer with micronutrients. Iron, copper, manganese, boron, and zinc are among these nutrients. Don’t think that a fertilizer designed for cedar trees or a general garden fertilizer would benefit citrus plants. When selecting a fertilizer, make sure it is made explicitly for citrus plants. When deciding on the best citrus fertilizer, consider the tree’s age, how recently it was planted, and the soil’s natural nutritional concentration. As the tree becomes older, you may skip the dormant season and extend the interval between active growth fertilization to once every two to three months.

Now, my friend, we are just getting started.

FAQs:

  • Question: When should you fertilize your citrus trees?

Answer: Citrus should be fertilized twice a year, between August and February. It’s a good idea to rotate fertilizers, such as Dynamic Lifter in August/September and Complete Citrus Food in February. Keep them adequately hydrated when new fruit is developing on citrus trees in the spring and early summer.

  • Question: What is a natural fertilizer for citrus trees?

Answer: Natural fertilizers like compost and manure are often used. The nitrogen-phosphorous-potassium, or N-P-K, ratio of compost ranges from 1.5-0.5-1 to 3.5-1-2. The N-P-K ratio of chicken dung ranges from 3-2.5-1.5 to 6-4-3, but the ratio of steer manure is generally less than 1-1-1.

  • Question: Are eggshells good for citrus trees?

Answer: Citrus plants benefit significantly from eggshells. They are high in calcium and other trace minerals, which can aid in the growth and health of your tree. You have the option of crushing and burying the eggshells or drying and powdering them.

  • Question: Why are the leaves on my citrus trees turning yellow?

Answer: Overwatering or nutrient shortage are frequently the causes of yellow leaves or chlorosis on citrus trees. Citrus plants require frequent watering, especially during the warm months. Still, overwatering can drain nutrients from the soil and produce root rot. Overwatered trees’ leaves frequently turn yellow and drop.
