Hippeastrum traubii 5 Pieces Seeds Package : 5 seeds Soil & Potting: Requires a highly porous, fast-draining potting mix. Combine standard potting soil with generous amounts of perlite, coarse sand, or pumice to prevent water retention. Use a small container, as the roots thrive when slightly restricted. Planting Depth: Plant the mature bulb with one-third to one-half of the bulb exposed above the soil line. This keeps the bulb neck dry and actively prevents rot. Watering: Water thoroughly when the top inch of soil dries out. Keep the medium lightly moist during its active summer growing season, but never allow the bulb to sit in standing water. Feeding: Apply a balanced liquid fertilizer every 2–3 weeks during active foliage and flower development.
