Bletilla striata planting techniques

1. Land selection and land preparation

Choose loose, fertile sandy loam and humus loam, in a warm, slightly shaded and humid environment; it is not cold-tolerant. When planting on well-drained mountainous land, it is best to choose a shady slope of virgin wasteland for planting.

If there is no farmyard manure, 50 kg of ternary compound fertilizer can be broadcast, or 100 kg of organic fertilizer can be applied. Then plow again to mix the soil and fertilizer evenly.
