How to keep Justicia Flava.
Light
Yellow justicea is native to habitats like forest understories or rocky areas, where it grows in natural shade. It prefers partial sun but can tolerate both full sun and full shade, demonstrating its versatile and hardy nature.
Water
Yellow justicia thrives in dry conditions and needs balanced watering, ideally every 2 to 3 weeks. As an evergreen, it keeps its foliage throughout the year and requires regular moisture, even during its dormant period in the colder months.
Temperature
Yellow justicea comes from tropical areas, where the climate is generally warm and humid. Consequently, it is suited to high temperatures and moisture. It does not tolerate abrupt temperature changes and prefers a steady temperature, so avoiding indoor temperature swings is important. It typically cannot withstand cold and needs warmer conditions to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.
Fertilizer
The best time to fertilize a Yellow justicea is in early spring, as it comes out of dormancy. This encourages overall growth and flower development. Fertilizing improves the foliage, stems, and branches, and encourages large, vibrant, long-lasting flowers. It helps move nutrients from the roots to the flowers and enhances the plant’s health and resistance to disease.
Pruning
Yellow justicea showcases vibrant yellow blooms and benefits greatly from pruning in early spring. By removing dead branches, you promote healthy growth. Trimming new growth not only enhances flowering but also helps maintain a compact shape. Pruning improves air circulation and reduces the risk of disease, ultimately encouraging the plant to thrive.
