Citrus fruits like mandarin require a climate similar to that of the Mediterranean, with mild winters and hot summers.

Medium and constant temperatures are perfect for good budding and even fruiting. It does not matter if there are drafts because it is a hardy plant.

Caring for potted mandarins

Best substrate for our mandarin

The choice of substrate This is an important point for many plants, but not especially for citrus fruits, whose hardiness allows it to adapt to all types of soil.

The universal substrate It is a good alternative because provides nutrientsis mildly acidic to keep nutrients unlocked and provides good drainage of excess water.

You also won’t need to place a layer of gravel or pebbles on the base. Only the universal substrate is sufficient.

If you want to further improve the substrate of your potted mandarin, you can incorporate a small amount (about 20%) with earthworm humus. It increases the concentration of organic matter in the substrate and provides additional nutrients (especially microelements) essential to your mandarin.

How to water your potted mandarin

One of the most important keys to caring for a potted mandarin is the irrigation approach, since we can run the risk of running out or, even worse, overdoing it and rotting the roots. .

Citrus fruits like tangerine are demanding on water, but being grown in a container changes the approach a bit.

An approximate watering schedule for a container-grown tangerine would be as follows.

  • Watering in spring and summer: 2 to 3 times a week.
  • Watering in autumn and winter: 1 time per week.

How much water for irrigation?

We recommend that you always apply the same amount, playing with the frequency mentioned above. In general, we will apply a quantity of 1/5 part of the volume of the jar.

For example, if our tangerine is planted in a pot with 5 liters of water, we will apply 1 liter of water. As a tip, it should be noted that some of the water, about 5-10%, flows through the holes in the base. It will also help remove accumulated salts and keep the substrate in better condition.

Fertilizer application

Tangerine consumes a large amount of nutrients, although much less than that planted in the garden. Being contained in a volume-limiting substrate, it is more dependent on the replenishment of elements such as nitrogen, phosphorus, potassium and others, including micronutrients.

You choose which type of fertilizer to choose, whether liquid or solid granules.

liquid fertilizers

Liquid fertilizers require more continuity in supply, but since they are applied mixed with water, assimilation is very rapid.

this solution NPK 7-5-6 with micronutrients It is quite complete for any crop, as it is quite concentrated. In general, we will apply a dose of 1 ml/L of water, in 1 out of 4 waterings, throughout the spring and summer.

solid fertilizers

They are more comfortable to applyespecially for potted trees, but you have less control over nutrition and its release into the substrate.

For the tangerine in a jar, we recommend the following composition, as it is very balanced and also provides microelements.

Possible pests and diseases

We will analyze each specific situation.

Pests: ribbed mealybugs or California red mites may appear on the leaves. On new shoots, aphids. All are easily removed by applying a cloth dampened with alcohol. Aphids, using potassium soap or spraying water with dish soap.

However, we may also be interested control its development to avoid having to constantly change the container of the pot.
