Light:
This hardy citrus hybrid thrives best in full sun, requiring at least 6-8 hours of direct sunlight each day. If grown indoors, place it in the sunniest location, such as a south-facing window or a bright greenhouse.

Soil:
Plant in well-draining soil with a slightly acidic to neutral pH (6.0-7.0). A sandy or loamy mix is ideal. If planting in a container, use a high-quality citrus potting mix. Good drainage is crucial to prevent root rot.

Watering:
Water consistently, keeping the soil evenly moist but not soggy. Allow the top inch of soil to dry out before watering again. During the cooler winter months, reduce watering frequency, as the plant's water needs decrease in dormancy.

Fertilization:
Feed with a balanced citrus fertilizer every 6-8 weeks during the growing season (spring to early fall). Use a formula that includes micronutrients such as magnesium, iron, and zinc to ensure vibrant, healthy foliage and fruit production.

Temperature & Humidity:
The Ichang "Lemon" is cold-hardy down to around 10-15°F (-12 to -9°C), making it an excellent choice for gardeners in cooler climates. For best results, maintain temperatures above 50°F (10°C) during active growth. If grown in a container, move it indoors or to a protected area when temperatures dip below 20°F (-6°C).

Pruning:
Prune in early spring to remove dead or damaged branches and to shape the plant. This helps improve air circulation and allows sunlight to reach the inner branches, promoting healthy growth and fruiting.

Pests & Diseases:
Watch out for common citrus pests such as aphids, spider mites, and scale insects. Treat infestations with insecticidal soap or neem oil as needed. Ensure good airflow around the plant to reduce the risk of fungal diseases like root rot and citrus canker.

Harvesting:
Fruits typically ripen in late fall to early winter. Harvest when the fruit is fully yellow and slightly soft to the touch. The tangy, aromatic flavor of the Ichang "Lemon" is perfect for making lemonade, marmalades, or adding a citrus twist to your favorite dishes.

Container Growing:
If growing in a pot, choose a container with excellent drainage and repot every 2-3 years to refresh the soil and provide more space for the roots. Be sure to select a container large enough to support its moderate growth.

Winter Protection:
Although cold-hardy, young plants may benefit from additional protection during extreme cold spells. Use frost blankets or mulch around the base to insulate the roots during winter.
