This plant prefers well-draining soil, ideally sandy or loamy. Aim for a slightly acidic to neutral pH, between 6.0 and 7.0, and enrich the soil with organic matter to boost fertility.
๐ผ Planting Techniques
When planting, dig a hole 1-2 inches deep and space your plants 12-18 inches apart for optimal growth. The best times to plant are in spring or fall, allowing the roots to establish before extreme temperatures hit.
