Trees use seeds as a principal means of establishing their next generation in the natural world. Seeds serve as a delivery system for the transfer of genetic material from one generation to the next. This fascinating chain of events - the formation of tree seed to dispersal to germination - is very complex and still poorly understood.
Some trees can easily be grown from seed but, for some trees, it may be much quicker and easier to propagate them from cuttings. Seed propagation can be a tricky process for a number of tree species. A small seedling can be very tiny and delicate when first germinated and often require much more care than a cutting. Seed collected off tree hybrids or grafted stock can be sterile or the tree be off character from the parent.

What Stops Tree Seeds From Germinating
There are a number of important reasons a tree seed refuses to germinate under artificial conditions. Two major causes for unsuccessful tree seed germination are hard seed coats and dormant seed embryos. Both conditions are species specific and every tree species has to subject the seeds to unique conditions to assure germination. Treating the tree seed properly is necessary before germination occurs and a seedling can be assured.
