How to care for your potted citrus plant
Citrus fruits are ornamental and productive plants that, with the right attention, they offer fragrant blooms and tasty fruits throughout the year. Here is a complete guide to keeping them healthy and thriving.
Exposure
Citrus plants love light and prefer direct sun to grow healthily and vigorously. Good sun exposure promotes not only vegetative development, but also the production of fragrant flowers and intensely colored fruits. In dimly lit environments the plant tends to slow down growth and reduce flowering: it is therefore important to guarantee at least 6–8 hours of direct light per day. In the warmer months, if cultivated. in pot, it is advisable to periodically rotate the plant to ensure uniform exposure across the entire foliage.
Irrigation
Watering is essential for a citrus plant: the soil must be kept slightly moist, avoiding water stagnation which can cause root rot. These plants favor regular and moderate watering: prolonged drought reduces flowering, it compromises the quality of the fruit and weakens the plant. It is advisable to use water at room temperature and, if possible, poor in limestone. In summer the frequency of irrigation must be increased, while in winter it must be reduced, adapting to climatic conditions.
Fertilization
Fertilization is essential for growing your plants and maintaining their color. Always use a specific fertilizer for citrus fruits, varying the main components as a function of the period. From March to October it is advisable to use a fertilizer rich in nitrogen to support growth, while from November a controlled release fertilizer is recommended, to keep the nutrients accumulated in the previous months in circulation. A good fertilizer must contain macroelements such as nitrogen, phosphorus and potassium, as well as microelements such as iron and magnesium, essential to prevent leaf yellowing. Balanced fertilization supports flowering, improves fruit quality and strengthens the plant's resistance to environmental stress. The autumn one, in particular, prepares the plant for vegetative rest and promotes vigorous recovery in spring.
I repot
Our citrus plants, thanks to their well-developed root system, they are ready for immediate repotting. After about two years from the first repotting it is advisable to transfer them into a larger container, using a specific draining soil for citrus fruits enriched with organic substance. Repotting allows the roots to grow correctly and to have more useful nutrients available for the development of the plant. We suggest increasing the size of the pot by approx 2-5 cm in diameter. It is important to choose pots with drainage holes to avoid water stagnation. After repotting, the plant should be watered moderately and placed in a bright place, avoiding too strong exposures in the first days. Repotting in the winter is not recommended.
Pruning
Pruning should be carried out at the end of winter, eliminating dry branches and suckers, and keeping the plant compact. This practice favors subsequent vegetation and stimulates spring flowering. It is also useful to remove branches that grow inwards, to ensure airy hair and reduce the risk of fungal diseases. Regular pruning also helps produce fruit of more uniform size and better quality. Once pruning has been carried out, lightly fertilize the plant. Avoid drastic pruning: citrus fruits bear fruit on the branches of the previous year.
Flowering
Most citrus fruits bloom in spring, with the exception of the Kumquat, which tends to flower in summer. Other varieties, like the Lunario Lemon, the White Zagara Lemon, the Carrubaro Lemon, the Meyer Lemon, he Lime, the Cedar and the Calamondino, they are re-flowering and can produce flowers several times during the year. To encourage abundant flowering, it is advisable to fertilize the plants in autumn with fertilizers rich in phosphorus and potassium. The fact that the plant does not flower, it could be caused by poor light or excess nitrogen. Flowering is a natural spectacle: the flowers, beautiful to look at and fragrant, they attract bees and pollinating insects, favoring fruit production. Re-flowering varieties are particularly appreciated because they give multiple cycles of flowers and fruit, making the plant decorative all year round.
Fruits
Our citrus plants not only beautify the environment, but they produce fruit that is tasty and safe to consume, comply with strict quality criteria. Fruits are rich in vitamin C and antioxidants, precious for daily well-being. Grown with care, they offer an authentic and natural taste, ideal both for fresh consumption and for transformation into jams, liqueurs and sweets. The presence of fruits on the plant increases the ornamental value, making it perfect also as a decorative element in gardens and terraces. The final color of the fruit depends on the variety and temperatures: a completely yellow or orange peel does not always indicate full ripeness.
Cold resistance
Citrus fruits are sensitive to frost and must be protected during the winter. If the temperature drops below 5 °C, it is advisable to cover the plant with non-woven fabric. In particularly cold areas, potted plants should be moved to sheltered environments, how or veranda. The non-woven fabric helps maintain a more stable temperature and protects the plant from night-time temperature variations, guaranteeing your health even in the harshest months. Avoid leaving the pot in direct contact with cold soil: use a booster.
Citrus fruits can be subject to some common pests, especially in the warmer months or in poorly ventilated environments. Recognizing them and intervening promptly allows you to keep the plant healthy and productive.
Let's discover them together!
Cochineal
It is among the most frequent parasites. It appears as small white shields on leaves and branches, often accompanied by a sticky substance (creeping).
How to intervene:
- Remove manually with a cotton ball and water.
- Wash the plant with water and Marseille soap.
- Use specific products only if the infestation is advanced.
Aphids
They especially affect tender shoots, deforming them and leaving honeydew.
How to intervene:
- Rinse the sprouts with water.
- Apply soft potassium soap or specific products.
Acari (red spider)
More frequent in summer with hot and dry climate. They cause punctiform yellowing and, in the most serious cases, thin cobwebs.
How to intervene:
- Increases environmental humidity.
- Spray water on the leaves (only at cool times).
- Use specific acaricides if necessary.
Fruit fly
It stings ripe fruits causing small spots and internal rot.
How to intervene:
- Collect ripe fruits without leaving them too long on the plant.
- Use attractive traps in the summer season.
Where to place your potted citrus plant depending on the season
Primavera: move it outside or to ventilated environments, resuming irrigation and fertilization;
Estate: place it in full sun, irrigating frequently;
Fall: reduce watering, distributing controlled release fertilizer;
Winter: protect her from the cold, keeping it dry and trying to let it get as much light as possible.
Remember that strong wind, poor light and irregular watering can affect more than the temperature itself.
