Germination, Sowing and After Care Information for
Siberian Pea Tree (caragana arborescens)
Although these seeds have only a very shallow dormancy they have a hard seed coat and require pretreatment for successful germination to occur. Without pretreatment it is likely that 10% or less of the seeds will germinate. A combination of a variety of seed pretreatments is usually necessary to make the seed coat permeable so that the seed embryo can take up water and begin to germinate.
The first (and easiest) method is place the seeds in a container and pour warm (not boiling!) water over them and leave them to soak for between 12-24 hours. Seeds that have been successfully pretreated will have swollen to around 2-3 times their previous size. Remove all swollen seeds as these will be damaged by further pretreatments. These can be sown immediately. This warm water treatment can be repeated up to 3 times, making the water a little hotter each time. Seeds that remain small need to be dried for further treatment.
Seeds that have swelled should be ready to germinate and will take 3-4 weeks in temperatures of 20 Celsius. Seed that have not taken up water can be cold stratified for up to around 4 weeks. To do this mix the seeds with a small amount of 50/50 compost and sharp sand -this must be moist but not enough to be able to squeeze out water with your hand. Put the mixture of seeds and compost in a loosly tied freezer bag and place in the fridge for 4 weeks. After this time the seeds are ready for sowing.
Sow in pots or seed trays of good quality compost at a depth of about 1cm (just less than 1/2 inch) The seed usually germinates in under 4 weeks at 15-20°c. Gerination and growth are usually pretty quick and plants may grow to between 15 and 45cm (6-18 inches) during their first season. Plant them out into their permanent positions in late summer if they have made sufficient growth, otherwise during the following year.
