I went to their site, the site wanted to download some program onto my machine, decided to stay out of there.
Moisture must be present so that the seed can metabolise the proteins that keep the seed dormant.
I would not bother. Daconil can cause more problems than it cures. Hydrogen peroxide is harmless to seed at 3% concentration, and it breaks down quickly, usually less than 24 hours, usually in minutes. If you want to tilt the odds, add a mycorrhiza inoculant to the damp media. This will help tilt the odds in favor of ''good soil microbiome''.
Well you are in Maryland, calamondin are not hardy there, grafted or on their own roots. They will grow well on their own roots, especially as a potted plant. Grafting is for in the ground orchards, to stave off nematodes, and other soil born diseases and to add one or two degrees of freeze resistance. Maryland is far too cold for the little bit of freeze resistance to matter. Make better bonsai on their own roots. Note, they have wonderful dark brown bark, which you won't see until the tree is somewhere over 20 years old. Worth starting now, to eventually enjoy once they get old enough.
Just plant out in spring, as planned. Label the pot well. Then leave the pot outside, through the next winter. Additional seedlings will germinate the second summer. Typically a few will sprout the first year, the rest the second year.
Nothing tricky here. Possibly like other maples, if seed was too dry, some will hold off germinating until second summer.
Yes, see my notes in the referenced thread. Bottom heat is your friend for germinating Baobab seed. (If you decide to get fancy)
They will be fine on their own roots. Citrus make great bonsai, especially the dwarfs, like genus Fortunella, and dwarf citrus like Calamondin. They will have bright green bark and stems for the first 20+ years, but once they get enough age bark suddenly becomes a wonderful rough sandpaper texture and dark brown or black. Beautiful on a tree with fruit.
give them away as fast as you can. (I don't like 'em.)
I got one years ago, sold openly at the Chicagoland Flower and Garden Show, hundreds of vendors and thousands of people milling around, there it was, sitting proud in the middle of a cactus display. Go figure. Legality? You technically can not outlaw a native species. You CAN outlaw sales of a native species, but the plant itself is a different matter. Mine rotted away due to overwatering.
Only do this when it is safe to start them outdoors, IN FULL SUN, if you start them indoors growth will be weak and leggy. Absolutely need full sun from the moment they sprout.
Good plan
By the way. I have started dozens of batches of seed by stratifying in my refrigerator, usually 3 or 4 different species a year. Been doing bonsai many decades, so lots of seed experience. If stratified seed starts germinating, and it is too early to plant them directly outside, it is usually NO PROBLEM to just keep the germinating seed in the refrigerator until safe to put outside. I've held seed cold, in the original bag they were stratifying in, for 2 months after germination started. Seldom loose more than one or two of the seedlings this way. I find outdoor full sun, natural sun growth is far superior to the weak leggy growth you are likely to get indoors on the window sill or under lights. Especially with full sun species. Some shade lovers do okay under lights. But your best bet is just hold the seedling in the cold refrigerator until safe to plant outside rather than start them indoors. Better growth characteristics. Fewer things to remember to water around the house too.
Oak seed, acorns, normally sprout a singe root in autumn, or early winter. Then they enter a dormancy, and then will begin to grow normally 3 months later when planted out in spring. It you see a root from an acorn start, don't pull it out of the refrigerator and pot it up. It won't grow, it will still need another 2 to 3 months of cold storage to fully release it from dormancy. It is perfectly normal for oak to sprout this way. Similar with chestnuts, and chinquapins.
