Honey locust is the legume tree that dropped medieval armor for suburbia: wild types bristle with thorns; nursery cultivars go bare-legged and polite. Drought-tough, sun-hungry, and happy on poor soils — it fixes nitrogen enough to matter in polyculture talk without pretending to be a bean patch. ☀️💧 Sun and Water Requirements: - Full sun for strong form and pod production. - Tolerates drought once established; wet feet invite decline. - pH flexible; compaction bothers it less than most ornamentals. ✂️ Methods to Propagate: - Seeds: scarify and soak — hard seed coat is a gatekeeper. - Grafted cultivars: propagate by budding to keep thornless, predictable habits. - Transplant young bareroot trees in cool, wet seasons.
