Gardening Advice

Asclepias is relatively easy to grow, but keeping the following points in mind will help produce more beautiful blooms:
It thrives in sunny locations and develops its vibrant colors best when exposed to ample sunlight.
With its tolerance to drought, it requires well-drained soil. Slightly sandy soil is preferable over highly fertile soil. Avoid excessive fertilization, as it can reduce the number of flowers.
Planting seedlings in early spring allows you to enjoy flowers from summer through autumn.
While pruning is rarely necessary, removing withered parts after flowering will encourage new blooms.
Asclepias is somewhat sensitive to cold, so in harsh winter regions, it is recommended to grow it in pots and move it indoors or to protect it from frost.
