DETAILS

Care Instructions
Flame Acanthus thrives in bright, direct sunlight and prefers moderate temperatures. It can tolerate dry conditions but benefits from occasional watering. This plant does well in environments with moderate humidity and should be protected from frost.
Soil
This shrub prefers well-draining loamy soil. It can tolerate poor soil conditions but thrives best in soil that is not overly rich in nutrients. Good drainage is essential to prevent root rot.
Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied during the growing season to support healthy growth. Fertilize sparingly, as over-fertilization can harm the plant.
Repotting
Repotting is generally not necessary for this shrub, but if grown in a container, it can be repotted every 2-3 years. Choose a slightly larger pot with good drainage and fresh loamy soil.
Propagation
Flame Acanthus can be propagated through seeds or cuttings. The best time to propagate is during the spring or early summer. Take cuttings from healthy, non-flowering stems and root them in a well-draining soil mix.
Pruning
Pruning is beneficial for maintaining the shape and encouraging bushier growth. Prune in late winter or early spring before new growth begins. Remove any dead or damaged branches.
Toxicity
Anisacanthus quadrifidus is not known to be toxic to pets or humans. However, it is always best to keep plants out of reach of pets and children to avoid any accidental ingestion.
Additional
Flame Acanthus is a drought-tolerant plant that can add vibrant color to xeriscapes and wildlife gardens. It is particularly attractive to hummingbirds and butterflies, making it a great choice for pollinator-friendly gardens.
