I ordered several different seeds to start a bonsai collection from the beginning. I understand that most seeds need cold stratification to germinate, however, I have some Ficus Microcarpa that say no cold stratification is needed. What kind of soil to I need to use for these tiny seeds to germinate? Also, after the cold strat. phase of my other seeds what is a good pre-made blend would be best for seedling transplant.

I have the following seeds:
Japanese Cherry Blossom
Olea Europeae
Japanese Black Pine
Ficus Microcarpa
Redleaf Maple
Chinese Elm
Scots Pine
Dwarf Hawaiian Umbrella
Crescentia alata
English Yew

Any help would be appreciated.

Sow in regular seeding mixes. These are often syerile which may help against fungi.

Cold atratify by just putting seeds outside. All potted up.
