Wasabia japonica

Wasabi seeds should be planted in well-draining soil, about 1/4 inch deep. Keep the soil consistently moist and place the container in a warm, shady location. Germination usually occurs within 2 to 4 weeks.

Some of plants may have very have specific germination requirements that may not be covered in these general instructions. 

Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here.  Germination times and germination temperatures are to be a guide only.  Many factors can DRASTICALLY affect this.


It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
