How and how to fertilize lemon at home

Lemon is one of the most common indoor citrus fruits. It is not a problem to acquire a small seedling of this culture, but it is much more difficult to grow a fully developed plant from it. An important role in this is played by timely and correct feeding.

Signs of a lack of batteries

The development of indoor lemon occurs in a limited volume of soil mixture, therefore, the size of its root system is approximately 30-40 times smaller than that of a specimen growing in the open field. It is the home plant that needs regular fertilization.

Determine the lack of certain nutritional elements by the following criteria:

  1. Nitrogen. The main signs of nitrogen starvation are pale leaf color, underdeveloped young shoots, and severe growth retardation.
  2. Phosphorus. First of all, its lack affects flowering and fruiting. It can be single or absent altogether. Also, the plant can turn black and fall off the leaves, develop ugly fruits.
  3. Potassium. The lack of this element is expressed in weakened development, the leaves begin to brighten first from the edges, then chlorosis gradually spreads to the interveinal space. The fruits ripen for a very long time and become soft.
  4. Calcium. Its deficiency very often affects the development of the root system. Also, with calcium deficiency, the tops of young shoots die off.

In addition to a deficiency of basic nutrients, lemon may also have a deficiency of trace elements. Most often he suffers from iron deficiency chlorosis. It is expressed in the manifestation of light areas in the interveinal space of leaves. Then the damaged tissues die off, and the leaves themselves fall off.

The main types of fertilizers

All fertilizers used for feeding indoor lemon can be divided into two groups. The first one is mineral fertilizers and complexes, the second one is organic.

Mineral fertilizers

From mineral fertilizers for feeding lemon, you can use ammonium nitrate. It effectively eliminates nitrogen starvation. It should be diluted to the state of a half-percent solution.

Very often it is supplemented with potassium salt. Of the phosphate fertilizers for dressing, it is best to use superphosphate. It is difficult to dissolve it in water. It is a long-lasting fertilizer. Therefore, you can simply take a small amount of granules and carefully embed it in the surface layer of the soil.

Also, during the period of intensive growth from March to August, complex mineral fertilizers can be used for fertilizing. In this case, it is best to choose those that are intended for indoor citrus crops.

Organic fertilizers

Lemon is very responsive to organic inputs. However, in this matter, it is also worth observing moderation. An excess is no less harmful than a deficiency. Of the organic fertilizers for feeding lemon, fermented mullein or diluted bird droppings are most often used.

To prepare a mullein solution, fresh manure is poured with water and left for further fermentation for a week and a half. After that, the resulting infusion is diluted with water in a ratio of 1 part mullein to 10 parts of water.

To be more effective, a small amount of potassium salt and a few granules of superphosphate are added to the solution. You can also use chicken or pigeon droppings to fertilize lemon.

To prepare a working solution, 1 kg of raw manure is diluted with 10 liters of water. If the droppings are dry, the proportion changes slightly, 0.5 kg of droppings are added to 10 liters of water. The prepared solution should be used immediately. If this requirement is not met, most of the nitrogen will escape from it.

Fertilization chart for lemon

The fertilization scheme for indoor lemon is pretty simple. All top dressing is applied during the period of intensive crop growth from March to September. There is no point in fertilizing lemon during dormancy.

The first time fertilizers are applied at the beginning of March, at this moment nitrogen fertilizers are most often used. Then, once every two weeks, the lemon can be fed with a special liquid fertilizer for indoor citrus. In most cases, it contains not only basic nutrients, but also trace elements necessary for the plant.

Fertilizers are used with caution during various diseases and injuries. At this point, there will be more harm than good from feeding. If there is no opportunity to purchase specialized fertilizers, you can use folk methods. For example, sleeping welding shows a very good result.

Fertilizing lemon correctly at home is not difficult at all. You just need to closely monitor the condition of the tree and eliminate the lack of certain nutrients in time. And then your lemon will surely thank you with abundant flowering and give many fragrant and healthy fruits.
