Hippeastrum ramboi 5 Pieces Seeds Package : 5 seeds Substrate Mix: Needs a loose, organic, yet excellently well-draining soil mix. Combine standard fertile potting soil with a high ratio of coarse sand, perlite, or pumice to prevent water retention around the base of the bulb. Watering Strategy: Provide regular moisture during its active spring and summer growing phase. Keep the soil damp but never waterlogged. Reduce watering in late autumn to allow the bulb a mild seasonal rest. Lighting Needs: Thrives best in bright, indirect or dappled sunlight. Protection from scorching, intense afternoon sun is recommended to keep the foliage and flowers from burning.
