Broussonetia papyrifera

Broussonetia papyrifera: Broussonetia papyrifera seeds require stratification to germinate. First, soak the seeds in water for 24 hours to soften the seed coat. Afterward, wrap the seeds in a moist paper towel and place them in a sealable plastic bag. Store the bag in the refrigerator for 90-120 days to simulate winter conditions. After the stratification period, plant the seeds in a well-draining soil mix and keep them moist, but not waterlogged, until germination occurs.

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.
