Viburnum lentago

Nannyberry seeds need to undergo a process called stratification to break dormancy. Start by soaking the seeds in water for 24 hours, then sow them in well-draining soil, covering them lightly. Place the container outdoors in a location where it will experience natural temperature fluctuations over the winter. Germination usually occurs in the spring as temperatures warm up.

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.
