Hippeastrum Tweedianum 4 Pieces Seeds Package : 4 seeds Substrate Mix: Requires an ultra-porous, heavily aerated, and sharply draining substrate. A reliable choice for collectors is a mix of 2/3 coarse perlite or pumice and 1/3 peat moss, which allows water to flow through instantly without compacting the roots. Neck Exposure: Plant the bulb into a deep container, keeping at least one-third to one-half of the bulb exposed above the soil line. This structural placement ensures the neck remains dry and actively prevents fungal crown rot. Light Environment: Thrives under abundant, bright indirect sunlight. Provide filtered light or a gentle morning sun exposure, protecting the foliage from intense, scorching midday heatwaves. Watering Strategy: Water thoroughly once the top inch of the medium dries out. During the active spring and summer blooming phases, keep the medium lightly, evenly moist. Never allow the pot to stand in water trays.
