What is tha difference between growing n a colander vs growing in the ground?

Hi folks.

Sailor - I hope you don’t mind me jumping on your thread but I have just read it and have what I think is a related question.

I have adopted the Boon mix for all of my trees - pines and deciduous - pumice / lava / Akadama. But I’m now concerned as I think I might be doing it wrong. Added to this, I have just been watching Ryan’s video stream on the Chinese Elm whee he says we should be using 100% Akadama for deciduous!

@Mike_Hennigan and @Joe_Perry - I’d be interested to hear your thoughts on this.

Thanks,

Andy
