What I would like to ask is when is the best time to dig up the little maple trees next to the big tree for putting in a pot?

I would probably wait for spring. When you dig them, up, make sure some of the roots come with the sucker. Keep them well watered and in the shade. When you see new leaf growth, they are ready to be transplanted into the ground. This process will not hurt the mother plant. Note: Depending on their size, you may want to pot the little trees up for at least a whole season before planting out in the yard. This way they will be able to form stronger roots.
