Water: Ground plum hails from prairie regions and adapts well to alternating wet and dry conditions, demonstrating moderate drought tolerance. Weekly watering mimics natural precipitation, supporting growth during active seasons when moisture aligns with its needs.

Fertilize: For ground plum, use a balanced fertilizer to enhance growth and fruiting. Apply a slow-release granular fertilizer with equal NPK every 6-8 weeks during the growing season. Water ground plum before and after fertilization, and reduce feeding in winter. Incorporate compost for organic enrichment.

Pruning: Ground plum thrives with early to late spring pruning, focusing on removing dead stems for improved airflow and light. Pinching young shoots promotes bushiness. Avoid heavy pruning to reduce stress, aligning care with the plant's growth cycle for optimal health and yield.

Propagation: Ground plum is a hardy plant that propagates well from seeds. Use well-draining, moderately fertile soil and scarification to improve germination. Sow seeds at a shallow depth in sunlight and maintain consistent moisture until seedlings are established for optimal growth and healthy fruit yields.
