JMs: Pots vs. Pots in ground

CEFreeman(DC/MD Burbs 7B)August 2, 2012

Hi all!

I have 70 or 80 JMs in pots. I've had a lot of history (much of it recorded here) with tornadoes taking down my shade trees, etc. These JMs are the ones that have survived full, absolute horrible, dry Maryland summers for at least 8 years.

Many I've placed in the yard, since they've survived and are thriving.

Now, there are some I will just have to keep in pots. Here's the question.

I have most in pots buried in the gardens. They don't seem to differentiate between pot dirt and ground dirt, so they root like crazy. If I put them into pots with a dish under them, will the remain somewhat contained?

Every couple of years I have to repot. I hate the trauma of tearing them out of the ground and their too-small pots. I'm thinking if I were able to contain their root growth somehow, it won't be so hard on me them.

What's your experience?

Thanks,

Christine

I've only had a couple root thru into the ground,but I check every year to see if they need re-potting so this keeps it to a minimum.Perhaps yours are too big and too numerous to lift them annually?Perhaps a gauze over the bottom of the pot would stop large roots appearing? not sure.
The thing is about putting anything under the pot is you'll miss a big advantage of sinking pots.The pot soil in contact with the garden soil stops any standing water from accumulating in the pot,the same way as 'wicking'.

Christine - you might benefit from something I wrote about trees grown in pots over on the container gardening forum. I'll leave a link. It's not about bonsai, though that's where my understanding of how to properly maintain trees with vitality as the focus over the long term comes from.
