Advice on growing Ginko biloba from seed

I have just obtained some ginko seed which i am interested in growing into bonsai and was wondering if anybody has any advice on this topic??

Keep them for sowing next spring. They need no chilling treatment. I sowed mine after scarifying them very carefully with sandpaper until the outer shell of the large round seed had been breached. Then just bury them in in damp 50/50 sandy compost and keep warm. A sunny windowsill, greenhouse or propagator. They came up like cress but very much larger! Pot them up into larger pots and carefully arrange the roots after a couple of months.

Once you have a few growing they are very easy to reproduce by cuttings.

cant i just plant plant them as they are next spring without sanding them down??

There are many kinds of seeds that require scarifying before they are planted. This is because in nature, the fruit is eaten by animals or birds and the wall of the seed is thinned by the animal's digestive juices or the stones in a bird's gizzard. If you plant such seeds without treating them with sandpaper or nicking the seed with a knife, your chances of germination are much lower.

It's not that much work. And, if you want the seeds to germinate . . .
