Care Instructions
Strophanthus gratus thrives in bright, indirect light and prefers moderate temperatures. It requires high humidity and should be kept in a warm environment. Regular watering is essential to keep the soil evenly moist, but avoid waterlogging. This plant can be grown both indoors and outdoors, provided it is protected from direct, harsh sunlight.Soil
Strophanthus gratus prefers well-draining loamy soil that retains moisture without becoming waterlogged. A mix of loam and organic matter works well. Ensure the soil has good drainage to prevent root rot.Fertilizer
Use a balanced fertilizer with a nutrient composition of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to support its growth and flowering.Repotting
Repot Strophanthus gratus 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, shake off excess soil, and place it in the new pot with fresh soil mix.Propagation
Propagate Strophanthus gratus through stem cuttings. Take cuttings during the growing season, preferably in spring or early summer. Dip the cut end in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and provide high humidity until roots develop.Pruning
Prune Strophanthus gratus to maintain its shape and encourage bushier growth. Pruning can be done after the flowering period. Remove any dead or damaged stems and trim back overgrown branches.Toxicity
Strophanthus gratus is toxic to both pets and humans. All parts of the plant, especially the seeds, contain toxic compounds that can cause severe symptoms if ingested. Handle the plant with care and keep it out of reach of children and pets.REVOLUTIONIZE YOUR PLANT CARE
