I have a packet of Acer nigrum seed ordered from Sheffield's. After about 50 days of stratification, 2 of the seeds have already sprouted little roots about a quarter inch long. The rest still appear dormant.
I potted them up and they're under a small CFL grow light in a fairly cool basement (65-67 during the day, around 55 at night), since placing them out in the 9 degree temps this morning didn't seem to be a good idea!
Questions for anyone who has grown them:
1. How long will it take from this point before I see the seedlings emerge above the soil?
2. Will this super-early start mess up their natural cycle of dormancy this fall?
3. Since Sugar Maple and it's variants are pretty shade tolerant as seedlings, if I transition these trees to the outdoors around early April and put them in the shade outside, will they be likely to acclimate OK to outdoor conditions? I don't want to burn them in the sun - but even my shadiest spots still get SOME sun, an hour or so at least.
4. About how much growth is realistic in the first season?
