Do you have any orange, mandarin, lemon or any other fruit tree of the Citrus genus? Then you should know that are plants that need regular fertilizationsince in this way it is avoided that they have chlorosis problems, as well as that they become weak and become diseased trees. And it is that it is usually thought that plants that are on land can be fine only with water and with the nutrients they get from the soil, but that is not so.
From the first moment in which the roots begin to absorb them, the countdown begins for that land to run out of them … unless it receives organic matter that, when decomposed, will keep it fertile. That is why it is worth asking: What is the best fertilizer for citrus fruits?
When do you have to fertilize citrus?
Guano powder.
Citrus fruits are evergreen trees that are very favored by mild climates, without frost or very weak. Because of that, its growing season begins in springwhen the minimum temperature starts to exceed 10 degrees Celsius, and ends in autumnwhen it drops below 10-15ºC.
Taking this into account, it is highly advisable to fertilize during all those months, especially in summer, since this way we will get healthy plants, with enough energy to produce a large quantity of fruits.
What is the best fertilizer for citrus fruits?
As we are talking about plants whose fruits are edible, the ideal is to use Organic fertilizersLike compost, mulch, or the guano (get it here!), since in this way we will also contribute to improving the quality of the soil in which they grow without harming the environment or the life in it.
But, can it be fertilized with compound / chemical fertilizers? Yes, of course, but only if the instructions specified on the packaging are followed to the letter. And, although its effectiveness is faster, the risk of overdose is much higher than if organic fertilizers were used.
What are the symptoms of nutritional deficiencies in citrus?
Leaves lacking in iron.
These trees usually have problems due to the lack of some mineral / s in the soil, especially if they are grown in clay and compact soils. To find out what they lack, below we tell you what are the nutritional deficiencies they may have:
- Sulfur (S): the leaves turn pale green, and the tips are curved.
- Boron (B): the leaves turn yellow and deformed, and the younger ones take on a tan tone.
- Soccer (Ca): the growth rate slows down, and the plant loses vigor.
- Phosphorus (P): lower flower production, and exaggerated growth of the fruits, which also have less juice.
- Iron (H): the leaves turn yellow, leaving the veins well visible.
- Magnesium (Mg): the leaves, especially the old ones, turn yellow, and the fruits remain small.
- Manganese (Mn): irregular yellow spots appear on young leaves.
- Nitrogen (N): leaves turn yellow and stay small.
- Potassium (K): old leaves wrinkle and curl, and fruits do not reach their original size.
To avoid them, it is highly advisable to use different organic fertilizers but without mixing; that is, one month we put a layer of guano that is very rich in the main nutrients (N, P, K), another month we put bone meal, which is rich in calcium, etc. Anyway, if you have doubts, contact us .
