Germination, Sowing and After Care Information for
White Mulberry (morus alba)
Soak the seeds in water for 24 hours and drain.
Next prepare a free draining substrate into which the seeds are to be mixed, moist sand is thought to give the best results for this although you could use a 50/50 mixture of compost and sharp sand, The chosen substrate needs to be moist (but not wet), if you can squeeze water out of it with your hand it is too wet and your seeds may drown and die.
Mix the seeds into the substrate, making sure that their is enough volume of material to keep the seeds separated. Place the seed mixture into a clear plastic bag (freezer bags, especially zip-lock bags are very useful for this -provided a little gap is left in the seal for air exchange) If it is not a zip-lock type bag it needs to be loosely tied. Then write the date on the bag so that you know when the pretreatment was started.
The seeds require a cold period to break the dormancy that is naturally found within them, this is easily achieved by placing the prepared bag of seeds and compost mix in the fridge (4 Celsius or 39F) for around 8 weeks. It is quite possible for the seeds to germinate in the bag at these temperatures when they are ready to do so towards the end of the pretreatment period, if they do, just remove them from the bag and carefully plant them up.
For larger quantities it is easiest to sow the seeds in a well prepared seedbed once the cold pretreatment has finished and wait for the seeds to germinate. Seeds that are ready to germinate will begin to split, if they have not the pretreatment is not yet complete or has been ineffective due to incorrect temperatures or incorrect moisture content of the pretreatment medium and the pre treatment process should be started again.
Do not expose newly sown seeds to high temperatures (above 25 Celsius) otherwise a secondary dormancy may be induced and the seeds will not germinate until they have been pretreated again. Germinated seeds can be planted in deep pots or plug trays in a good quality compost. Keep the seedlings well watered and weed free.
Growth in the first year is usually between 10 and 30 cm and usually trouble free. Growth accelerates in the second and subsequent years. Allow them to grow for 2 or 3 years before planting them in a permanent position.
