Katsura tree seed germination requirements

Hi. I am new to this site and I was wondering if I could see if I could get help with Katsura trees. I recently went to the park and stumbled upon a beautiful Katsura tree. It smelled of cotton candy, apples, and brown sugar, just as everyone has told me. A week or two after, I went back to the tree and collected a bunch of it's seeds. I know they are the small winged ones inside the banana shaped pod, but I don't know what the requirements to germinate them are. I have searched everywhere on google but with no luck. Im looking to see if I could possibly just plant them in my backyard this november to have them come up in the spring, but they do seem to be very fragile seeds and I don't know if I need to give them a little tlc :) If I can't just pop them them in the ground overwinter, what should I do inside to recreate the requirements indoors? I do not have a greenhouse, although I would love to build one. The Katsura tree is a beautiful specimen and I would love to utilize the seeds I collected. All help is much appreciated :)

Katsura: Cercidiphyllum japonicum , no pretreatment needed, sow @ 70ºF for germination in as little as 2 weeks

Thank you so much for your speedy response morz8! I put that up last night and you responded within a day! Just two more quick questions. What kind of medium do you suggest and how deep should they be sown? Thank you so much for your time :)

Sow the small seed thinly, and barely cover, some light may be beneficial to germination. You can cover with a bit of grit or coarse sand - will help the seed to stay in contact with the moist medium while still letting some light through. Otherwise use a light layer of your same potting medium. Prepare nursery pots using a moisture retentive yet well draining potting medium.....many are good, stay away from Hyponex brand. Scatter the seed, mist with water, cover lightly with grit and mist again. I like roots of trees, shrubs, to have room immediately to grow down - I sow in pots with 5" depth. If you are very attentive and not likely to forget to check, you can cover tops with saran wrap - removing it immediately at the first seed germinating so circulation of air is increased.

Thank you so much! You have really been a real help to me :)
As you know I love this tree and just can't wait to grow it. Hopefully I'll post some pictures of them growing when they do. THANKS :)
