Thank you for the quick reply. I purchased them from a at home nursery and he said he got the seeds off of his bloodgood. I saw the tree where the seeds came from looked like one to me but I'm no expert on this subject by far. I will post a pic of the tree the seeds came from. Maybe you can tell me what it is exactly. Should I stick to a smaller sized pot or will a bigger one be fine?

Raised from seed = your trees are not 'Bloodgood'. All the more so if the parent tree is a seedling also, rather than the true item*. But if they were a good purple this year you might want to grow them anyway. Just remember that they are not 'Bloodgood', but rather purple Japanese maple seedlings, with no particular specific designation other than atropurpureum.

Trees often get quickly crowded in pots so moving your seedlings on to larger ones would almost certainly benefit them. If the leaves are gone you can wash off all the existing medium and re-pot in entirely fresh material. Japanese maples are drainage sensitive so the breaking down of the potting medium into less aerated material should be kept ahead of.

*Tree in picture does not look like one to me, as far as can be seen using this view only. And anyway the point is moot, as your stock is seed raised and therefore not 'Bloodgood', even if the parent tree is

If seed grown, then they are not 'real' Bloodgood's but only species Acer palmatum that may have a very strong resemblance to the parent tree in terms of leaf shape, size and coloring. Or may not, once they begin to grow and develop. But that's not at all to say that they won't grow into great trees :-) Never met a Japanese maple, seed grown or otherwise, I didn't like!

If they are still quite small, the 1G container size is fine for the time being. 2 and 3 y.o. grafts are typically offered in 1G's and tat size seesm to be ideal for young trees. If you do not intend to plant them in the ground, next winter during the dormant period you may wish to increase the pot size but that is not an urgent concern. What is critical is the potting soil you should use. Look for something that is bark based, rather than peat or coir based and quite fast draining. There are many discussions on the forums regarding 5-1-1 or gritty mixes (discussed and explained in depth on the Container Gardening forum), which are mix-your-own soil blends if suitable, pre-packaged ones are difficult to locate.

ETA: Sorry - didn't mean to duplicate what was already stated but was posting at the same time as the previous comments.

Ok. Thx for clearing that up for me. When you say drainage sensitive do you mean I need to have good drainage to keep from getting root rot? Sorry for the newbie questions, just wanting to keep them alive.

Yes, Japanese maples can be more apt to fail under wet soil conditions than various other trees. Small plant containers develop a perched water table in the bottom half of the pot during watering, wherein the water backs up behind the drainage holes, then rushes out when field capacity (saturation) is reached. So with subjects such as Japanese maples needing good soil aeration you want to use a mix that is comparatively slow to break down, become less well aerated. And use pots with a normal tall shape, rather than low ones (azalea pots), so that the upper half of the potting soil column is as deep as possible.

I do plan to eventually put them in the ground but I have to do some preping to the spot where I want them. Probably will have the spot ready before spring (I hope). Also is it safe to just leave them outside or should I bring them in the garage on cold nights? I am going to see if I can find some of the soil you mentioned tomorrow at Lowe's or home depot.

You won't find any of that sort of soil at the box stores :-) Instead look for it at better independent garden centers. And these will likely need no additional winter protection in your zone. Only if your winter temps take a plunge into the low 20's for any length of time (more than a singe night or two) would I have concerns about moving them into the garage temporarily.

If you care to divulge your location more specifically, I might be able to provide some leads on appropriate bagged potting soil brands. Few national brands (like Miracle Gro, for example) offer this type of potting soil.

I'm in Macon, Ga. Thank you for the help. Didn't realize that this much went into growing trees until I looked them up after buying them lol.

In the east, I'd look for Farfard Soil products. Their Metro Mix or 52 Mix are bark based and extremely good for a packaged potting soil for any sort woody plants in containers.

Ok I'm going to get online and see where I can get some. Thank you for your help.

Told you they were tiny lol

You wont need to repot that big one for a while if you keep it in the container and dont plant it out...

What "big one"?? The ones in the photo above are tiny little specimens in a 1G container (or smaller) and WILL need repotting if not planted in the ground in the coming season.

The one in the black container looks to be bigger than one gallon honestly.

There is no need to rush to over pot a tree. It can stay in the that pot for a couple more years as these are slow growing trees anyway. IMO....
