Those A. pictum ssp mono (syn Acer mono) look like the real deal. That's great, because they hybridize very freely with platanoides, and the results usually look more like the latter. Of course the young leaves are always hard to qualify, but usually on pictum they have more platanoides characteristics, not less. Nice monspessulanums too!
Where did you get the seeds for A. monspessulanum ? Here, their natural habitat is around the Mediterranean, and in the parts of France that hace a mild climate. See : eFlore Yet, As the one I already showed on several occasions, they can now adapt very well in more northern parts of France. I live in Loiret (45), where so far it's a "grey area", no natural presence. Mine has never flowered : I prune it hard every year or every two years, perhaps that's why, but when it does, will it be the source of the Invading Montpelier Maple ? ;°D
@LoverOfMaples, had to have a look after you just mentioned it D. What a beautiful place there in Boston.
New try this year. In a basin 30X30X15 cm, full of composted little pine bark, only little composted bark, nothing else. In that growing medium you can water as you want. It’s easy and no sun scortch. Acer seeds: ’sango kaku’ . Fertiliser , liquid for géranium N.P.K.3.6.8. each month.
@opusoculi, the perfect growing medium that follows what seeds would grow in, in the wild. They look so strong and healthy. Do post updates in 2021 on these.
'Ryusei' seedling spreading. One unique looking one. It seems to be a slow grower. I'm going to slip pot them into a tad bigger pot so they can have more room to grow.
@LoverOfMaples good evening D, I love hearing about a unique maple, always some excitement at what might be. All looking good for 2021.
The seedlings as of this morning. Do I need to up-pot the larger ones in the 32 cell rootmaker tray or would they be okay staying there for the winter?
@kgeezy20 good afternoon Kyle. I would be looking at up potting as you say. But I would also be looking underneath to see if any roots are showing first. If they are, then IMO I would definatly re pot in September.
@kgeezy20 I use perlite to help aeration of my pots. But some friends use horticultural grit in it's place. I am paranoid about keeping my medium open, so add both. Maybe a bit of overkill, Lol.
There are roots coming out the bottom of several of them. It appears the plywood they were sitting on was wet enough as to prevent them from being air-pruned.
@kgeezy20 then IMO go for a repot. The roots in a good growing medium for the Winter, will set them up perfectly for next Spring and onwards.
Hi Kyle, is that A. chingii in the second picture? Looks a lot like it, but maybe sinense? Would be a nice find, time will tell. I planted 2 A. chingii in different expositions this past winter, they both did extraordinarily well with the sun and drought -- much better than the related A. sinense. Anything showing roots out the bottom I'd repot now. Just to be able to get through the work. So long as there's not big fresh growth on the top. I've been repotting A. velutinum from .25l to 1l or even 3l, the amount of root on these things is insane! It turns out I do have 5 pentaphyllums this year, I pricked them into quarter liters a few weeks ago. Re perlite, keep searching until you find a cheap source. Some people sell it very expensive. The dopers use a lot, I just bought some 70l bags for 20€ per from a hydroponics supply place. Otherwise a horticultural supply place might have it, mine was out of stock this time. Vermiculite is, it turns out, used as an insulation material when mixed with cement, you can get it very cheap from building supplies places. I haven't evaluated the quality, but don't see why it would be poor. I am using a little vermiculite with small plants, to keep from drying too fast, and to give the roots some smaller particles to work with. They seem to like it.
