- The seeds should first be soaked for 24 hours in clean water. Once the water has been drained off you need to cold stratify your seeds in the fridge for around 2 weeks at around 4 Celsius. The soaked seeds need to be put in or on some type of non-soil growing medium such as a damp paper towel, rockwool or sterile sand or vermiculite. We find that vermiculite works well.

- After placing your seeds in/on the moist substrate that you have chosen to use, you need to put them into a re-sealable plastic bag. Place the bag of seeds into the fridge and check them regularly to make sure the substrate remains damp but not saturated. After 2 weeks, the seeds should be ready to sow and will need to be placed at around room temperature (21 C/70 F for germination. 

- You can choose to germinate the seeds in the bag and then transplant them into compost or you can plant them onto compost and wait for seedlings to appear. If you are using the second option, cover the seeds with a fine layer of sieved compost or vermiculite. We find that covering the seed with a thin layer of vermiculite can give greater numbers of seedlings than covering with sand or compost. Do not bury them deeper than this as burying them too deep can ruin your chances of success. 

- The advantage of germinating them before moving them to soil is that the compost can hold more fungal and bacterial agents than your starting substrate.
