Wild Plum (prunus domestica)
To begin soak the seeds in warm water for 24 hours and then drain away the water.
Next prepare a free draining substrate into which the seeds are to be mixed, this can be a 50/50 mixture of compost and sharp sand, or perlite, vermiculite.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.
Next the seeds require a cold period to break the final part of the dormancy, this is easily achieved by placing the bag in the fridge (4 Celsius or 39F) for around 12 weeks. After this length of pre treatment the seed shells should begin to split
It is quite possible for the seeds to germinate in the bag at these temperatures when they are ready to do so, if they do, just remove them from the bag and carefully plant them up.
Once the pre treatment period has finished the seeds can be sown. Plant them about 10mm deep in a pot containing good quality compost. Keep them in a warm place at around room temperature and germination should begin within 1 or 2 weeks.
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.
Keep the seedlings well watered and weed free. Growth in the first year is usually between 30 and 60cm and usually trouble free. Allow them to grow for 1 or 2 years before planting them in a permanent position.
