The plant enjoys moderate humidity and should be kept in well-ventilated areas. Regular pruning helps maintain its shape and encourages new growth.Soil
Amsonia tabernaemontana prefers well-draining loam soil. It can tolerate a range of soil types but thrives best in soil that retains some moisture without becoming waterlogged. Adding organic matter can improve soil quality and drainage.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant in early spring and again in mid-summer to support its growth and flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.Repotting
