Sowing Guide 

As a native British plant that can survives very cold winters, blackberry seeds require a period of cold stratification for optimal germination - this is natures way of stopping seeds germinating at the wrong time of year, eg the autumn and being killed by frost/snow before can get established.  You could just do this the natural way  - sow the seeds in trays of compost, cover with some netting and leave outside over winter. Alternatively, thanks to fridges we can "trick" such seeds into thinking that winter has passed and now its time to wake up!

• Place the seeds in a small ziplock bag along with some slightly damp potting compost and place in the fridge for around 3 months
• Prepare seed tray or pots of well draining compost (ideally 50/50 compost / vermiculite mix)
• Sow seeds across surface and gently press to ensure good contact with soil.
• Add a thin layer circa 2mm of sieved compost to cover seeds
• Ensure compost kept moist at all times - spray with water bottle every other day
• Keep in warm light place but out of direct sunlight
• Germination should take 15-30 days
• Pot on once several sets of leaves
