How to keep Astragalus Coccineus.
Light
Scarlet milkvetch is a sun-loving, perennial herbaceous plant that comes from open habitats and often thrives in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Fertilizer
The best time to fertilize Scarlet milkvetch is in early spring, as it is coming out of dormancy and starting active growth. Fertilization supplies essential nutrients for healthy development. Although Scarlet milkvetch has relatively low fertilizer needs, an annual application can improve its survival and encourage stronger, longer-lasting flowers.
Pruning
Scarlet milkvetch boasts vibrant red flowers and is highly drought-tolerant. To promote its health and shape, prune the plant in early spring by removing any dead stems. Additionally, trim back overgrown branches to improve airflow. Always use clean tools for pruning to minimize the risk of disease and encourage abundant blooming.
