Soil Type

Water: Grassnut thrives in well-drained grassland soils and prefers moderate moisture. It requires weekly watering to maintain optimal hydration. Typically grown outdoors, grassnut benefits from a growing season that coincides with natural rainfall, reducing the need for excessive human watering.

Fertilize: For grassnut, use a balanced fertilizer in spring for growth and high-phosphorus types for flowering, fertilizing every 4-6 weeks. Follow label instructions to avoid root burn, especially during dormant periods. Seasonal adjustments are key for optimal health and bloom quality.

Pruning: Grassnut showcases star-shaped blooms on slender stems. Prune in early to late spring before growth begins, removing dead foliage to promote new growth. Deadheading enhances blooming and vigor, while pruning improves air circulation, minimizing disease risks and ensuring grassnut remains healthy throughout the season.

Propagation: Grassnut propagates well through seed sowing, ideally after the blooming season. Store seeds dry and cool until planting in well-drained soil with balanced moisture. Provide sufficient sunlight for seedlings, protect from extreme temperatures, and handle gently during transplantation to support healthy growth.
