What are the precautions for growing Calathea leopardina

1. Repotting

Repot once every other year, and it is best to use a fertile, loose, well-aerated and well-drained, slightly acidic soil rich in humus.

2. Pest control

Common pests mainly include scale insects, red spider mites, etc. For scale insects, depending on the severity of the infestation, spray 40% omethoate at 1000 times dilution, or 50% dichlorvos at 1000 times dilution, or 2.5% deltamethrin at 3000 times dilution for control. For red spider mites, control is generally carried out during the adult stage after the eggs hatch; you can spray 20% dicofol emulsifiable concentrate at 1000 times dilution, or 40% omethoate emulsifiable concentrate at 1000 times dilution.

3. Disease control

Common diseases mainly include southern blight and leaf spot, etc. For southern blight, you can add 70% quintozene to the soil at 0.2% of the soil weight to disinfect the soil, while removing the diseased plants and diseased soil, adding new soil, and ensuring good ventilation. For leaf spot, promptly remove diseased leaves, apply more base fertilizer, and strengthen disease resistance.

The above is about the growing methods and precautions for Calathea leopardina. Now let's see whether Calathea leopardina blooms!

How to grow Calathea leopardina: growing methods and precautions for Calathea leopardina

Calathea leopardina is rich in color, with several different colors on a single leaf, and its leaves are broad and unique, with many small black dots on the leaf surface, just like a kitten's eyes, especially beautiful and elegant, very suitable for indoor ornamental growing. So do you know the care tips for Calathea leopardina? Let's find out together below!

How to grow Calathea leopardina

Since Calathea leopardina is not cold-tolerant, nor drought-tolerant, and fears scorching sun exposure, direct sunlight will scorch the leaves, causing localized scorching at the leaf edges, stopping new leaf growth, and yellowing of leaf color, so shading must be noted during cultivation. But the growing environment should not be too shady either, otherwise the plant will grow weakly, and the patterns on the leaf surface of some variegated varieties will fade or even disappear, so it is best to place it in a spot with bright light but no direct sunlight for care. Calathea is relatively sensitive to water; during the growing season it should be watered thoroughly to keep the potting soil moist, but the soil should not become waterlogged, otherwise it will cause root rot and even plant death.

Since Calathea leaves are relatively large and water evaporates quickly, it has high requirements for air humidity. If the air humidity is insufficient, the leaves will immediately curl, reacting very sensitively, especially during the new leaf growth period, when the plant should be sprayed with water more often, otherwise dry air will make it difficult for new leaves to unfurl, cause leaf edges to scorch and yellow, and make leaves small and lusterless; varieties such as Calathea velutina will lose the velvety texture of their leaves, seriously affecting their ornamental value, so indoor cultivation must maintain air humidity at 70% to 80%. For the sake of appearance, you can often wipe the leaves with a clean soft cloth dipped in clear water, to make the leaves bright and glossy. In midsummer, when the temperature exceeds 35°C, it is unfavorable for leaf growth; attention should be paid to ventilation and spraying water to lower the temperature, giving the plant a cool and moist environment.

Growing methods for Calathea leopardina

1. Temperature

Calathea leopardina is native to tropical and subtropical regions and is heat-tolerant. It is suitable for a growing environment of 20-30°C. The winter growing temperature should best be maintained at around 16-18°C.

2. Light

A shade-tolerant plant, it likes semi-shade and should be placed in a bright spot indoors. Avoid direct sunlight and scorching exposure, etc., to prevent scorching of the leaves. In summer, do a good job of shading and ventilation.

3. Watering

During the growing period of Calathea leopardina, water thoroughly to keep the potting soil moist, while also taking care to avoid waterlogging the soil, to prevent root rot and even plant death. Since Calathea leopardina's leaves are relatively large and water evaporates quickly, maintain relatively high air humidity around it. You can often spray the leaves to keep the air around the leaves moist, which helps the leaves grow and unfurl. Once the leaves are found to be curling and shrinking, it indicates that the plant is in a water-deficient state.

4. Fertilizer

Follow the principle of "apply frequently and lightly." Stop fertilizing during the winter dormant period and during sustained high temperatures in summer.

Precautions for growing Calathea leopardina

1. Repotting

Repot once every other year, and it is best to use a fertile, loose, well-aerated and well-drained, slightly acidic soil rich in humus.

2. Pest control

Common pests mainly include scale insects, red spider mites, etc. For scale insects, depending on the severity of the infestation, spray 40% omethoate at 1000 times dilution, or 50% dichlorvos at 1000 times dilution, or 2.5% deltamethrin at 3000 times dilution for control. For red spider mites, control is generally carried out during the adult stage after the eggs hatch; you can spray 20% dicofol emulsifiable concentrate at 1000 times dilution, or 40% omethoate emulsifiable concentrate at 1000 times dilution.

How does Calathea leopardina overwinter

1. Temperature

In winter, if the temperature stays below 13°C for a long time, the leaves of Calathea leopardina will suffer cold damage. Therefore, the overwintering temperature for Calathea leopardina must not be lower than 13°C. It is recommended to keep the temperature above 15°C, otherwise it will inhibit the plant's growth.

2. Light

In winter, because light is relatively scarce, it is necessary to meet Calathea leopardina's light needs, so at this time let it come into contact with more sunlight. Also make sure not to let Calathea leopardina receive strong direct sunlight, as it may scorch its leaves.

When the temperature is too low in winter, it should not be placed in an overly hidden environment, as this will affect the plant's growth momentum and cause the patterns to fade or even disappear. When carrying out winter care, it is recommended to place the Calathea leopardina plant in a spot with no strong direct light and bright light for care.

3. Watering

Calathea leopardina has relatively large leaves, so during winter care you should also pay attention to ensuring sufficient water and moist potting soil. If the air humidity is insufficient, the leaves will immediately curl, affecting their ornamental value. But it should not be too much either, otherwise it will cause root rot, and in severe cases the plant will die. You can always pay attention to the water status of Calathea leopardina; if it lacks water, spray the plant more. Whether in winter or summer, Calathea leopardina should have a moist and cool growing environment.

As mentioned above, Calathea leopardina is evergreen all year round, and its adaptability and vitality are relatively strong, making it an especially easy-to-grow foliage plant. Although easy to grow, you still need to pay attention to the methods! If incorrect methods cause the leaves to turn yellow, it will seriously affect its appearance!
