Plant Wild Senna in well-drained soil with full sun exposure. Space plants 2-3 feet apart to allow for growth. Water regularly during the first growing season to establish a strong root system, then reduce frequency as the plant becomes drought-tolerant. Prune in early spring to encourage bushier growth and remove any dead or damaged stems. Fertilize with a balanced, slow-release fertilizer in early spring. Wild Senna is a hardy perennial that attracts pollinators and can tolerate poor soil conditions once established.
