Water: Okie bean prefers subtropical environments and requires consistent moisture, with an ideal watering schedule of once weekly. As an evergreen, it maintains foliage year-round, benefiting from steady hydration, particularly in full to partial sunlight when grown outdoors.

Fertilize: For optimal health, okie bean requires monthly feedings with diluted high nitrogen fertilizers during growing seasons. In dormancy, reduce frequency. Avoid over-fertilizing to maintain flowering, and water soil before fertilizing to enhance nutrient absorption and protect roots.

Pruning: Okie bean thrives with regular pruning in early to late spring, removing dead stems and controlling growth. Thinning promotes air circulation and shapes the plant. Clean, sharp tools ensure precise cuts, supporting healthier growth and disease prevention for a vigorous garden.

Propagation: Okie bean is an evergreen climber from South Africa, propagated by fresh seeds. Soak seeds overnight in lukewarm water, then plant in well-draining soil. Maintain consistent moisture and a warm, indirect sunlight environment for vigorous seedling growth.
