Why the rush to repot?
They "don't even know you!"  
Get to know your trees. They've been stressed in relocation. Let them adjust to their new home. Grow them out for 1-2 years. Get them good and healthy first.

When does Spring start for you?  A good time to repot is right as the trees show signs of Spring movement.  If your trees don't freeze, then you can repot them any time during Winter dormancy.

It is important to repot them if they need it and not to repot them if they don't need it.

Kid, are they in commercial nursery containers? In the bay area deciduous trees can be repotted any time after they go really dormant until they pop in the spring. For example, we repotted Japanese Maples in Hayward two weeks ago. But, you know what I am going to say next, get with BIB. Once you get on the mailing list, Boon sends out monthly emails with suggestions of work that can be done that month.

Both of them are in 1 gallon pots with, I guess u can say, "commercial soil??" I just want to get them out of that soil and put it in Boon's mix and a bigger pot. Both trees are about 9-10 inches tall. I think I'm going to let them grow for trunk thickening and turn them into shohin. Haha yes I did know u were going to say get with BIB lol I'm going on the 3rd for sure this time. I want to start the new year off right with a club. Thanks John and everyone. Happy new year

I would wait til the club meeting and let someone look at the soil to determine if they need to be repotted, or just slip potted. You could also ask about repotting them in pond baskets. I would never repot a future bonsai in a terra cotta pot, when something better is available. Larry

The terr cotta will work just fine for a few years.

well i got them in their new pots lastnight...put them in Boon's mix...hopping their gonna do good...happy new year everybody..

Um, did you clean out all of the old soil and reduce the roots to get them growing correctly?

Yes I did John. I followed Boon's repotting DVD to the T
