Growing Conditions for Purple Yam Seeds

Care During Germination
To aid germination, maintain a warm environment around 80-85°F (27-29°C) and keep the soil consistently moist. Utilizing a humidity dome or plastic wrap can help retain moisture and create a stable environment for the seeds.
Timeline for Germination
Germination can take several weeks to a couple of months. Once seedlings emerge, they should gradually be acclimatized to outdoor conditions, starting with a few hours of indirect sunlight before full exposure.
