Justicia ladanoides Lam. requires moderate levels of sunlight to grow. The plant prefers a location with bright but indirect light. Excessive exposure to direct sunlight may cause the plant's leaves to scorch and turn yellow.
Temperature Requirements
The suitable temperature range for the growth and development of J. ladanoides is 18°C – 27°C. The plant needs a warm environment, but it also grows well in mild temperatures. The plant is sensitive to frost and cannot tolerate temperatures below 10°C.
Soil Conditions
To support proper growth, Justicia ladanoides requires well-draining soil that is rich in organic matter. The plant prefers a slightly acidic soil pH between 6.0 and 6.5. The soil should retain moisture but not get waterlogged.
Water Requirements
The soil of the Justicia ladanoides plant should always stay moderately moist. Overwatering can cause root rot and adversely affect the overall health of the plant. The best way to water J. ladanoides is through the bottom-up method rather than from the top-down.
Fertilizer Use
To ensure optimum growth, Justicia ladanoides should receive a balanced dose of fertilizer every two weeks during the growing season. Use a complete and balanced water-soluble fertilizer. Avoid fertilizing the plant during the dormant season, which is usually in winter.
Cultivation Methods
Justicia ladanoides Lam. is an easy plant to cultivate as it is not very demanding. The ideal conditions for this plant include well-draining soil, a warm and humid environment, and partial shade. The plant can grow in full sun, but it is essential to keep the soil moist if grown in areas with high temperatures.
This plant is suitable for outdoor planting and indoor cultivation. When growing the plant indoors, ensure that it gets adequate sunlight. Growing the plant outdoors requires a fertile soil mix, plenty of watering, and occasional pruning to keep it healthy.
Watering Needs
Justicia ladanoides Lam. requires frequent watering to stay healthy and vibrant. Water the plant regularly during dry weather. When watering, make sure to soak the soil completely and allow the water to drain out to prevent root rot. Avoid letting the soil dry out completely between watering cycles.
On the other hand, over-watering can cause the plant to rot, so ensure that you only give it enough water that it needs.
Fertilization
While Justicia ladanoides Lam. does not require much fertilizer, it would help if you applied a slow-release fertilizer during the growing season. When applying the fertilizer, apply it sparingly to avoid burning the plant's roots. A high nitrogen content in the fertilizer can help promote leaf growth, and phosphorus can help promote the plant's overall health and development.
Pruning
Justicia ladanoides Lam. benefits from occasional pruning to maintain its shape and health. Prune the plant during the early spring to allow it to grow and develop new shoots. Use clean and sharp pruning shears to avoid injuring the plant while trimming. If the plant becomes too tall, prune it down to a manageable height, and remove any dead or weak branches as you go along.
