DETAILS

Care Instructions

Citrus aurantium requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a humid environment. Regular watering is essential to keep the soil evenly moist, but avoid waterlogging. The plant can be grown both indoors and outdoors, making it versatile for various settings.

Harvest

Citrus aurantium, commonly known as bitter orange, is typically harvested in the winter months when the fruit has fully matured and developed its characteristic color. The fruit should be picked by hand, using clippers or a sharp knife to avoid damaging the tree. It is important to handle the fruit carefully to prevent bruising. Harvesting should be done when the weather is dry to reduce the risk of fungal infections. The fruit should be stored in a cool, dry place to maintain its quality.

Soil

The plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is rich in organic matter to support its nutrient needs. Good drainage is crucial to prevent root rot.

Fertilizer

Use a balanced fertilizer with a nutrient composition of 3-1-2. Fertilize the plant every 4-6 weeks during the growing season to support its growth and fruit production.

Repotting

Repot Citrus aurantium every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, trim any damaged roots, and place it in the new pot with fresh soil.

Propagation

Propagate the plant through seeds, cuttings, or grafting. The best time to propagate is during the spring or early summer. For cuttings, use semi-hardwood cuttings and root them in a well-draining soil mix.

Pruning

Prune the plant regularly to maintain its shape and remove any dead or diseased branches. The best time to prune is after the fruiting season. Use clean, sharp tools to make clean cuts.

Toxicity

Citrus aurantium is not toxic to pets or humans. However, the fruit's bitter taste may be unpalatable to some animals.

Additional

Ensure the plant receives adequate airflow to prevent fungal diseases. Mulching around the base can help retain soil moisture and regulate temperature.
