Pots are better than trays, some trees create a longish root before you want to be pricking them out. That's best done as things get a bit warmer, otherwise they might rot.
My feeling is that exposure to all weather is part of the process. However, some trees will germinate whatever you do or don't do. This may be one of them
A lot of people fail with tree/shrub seeds because they do too much, or try and be kind to them.
