ROOT CONTROL GROWBAGS

I have inherited a eucalyptus bush about a foot high, which has been living in a window box for many years! My garden is tiny though and I am reluctant to plant it directly into the lawn, ad these do turn into very large trees...which root control bags are best for planting it into the lawn and do they eventually decompose over time? I had considered planting into a large pot but my patio is already full Thanks.

Think about whether the tree will be in the way if you plant it in the lawn.  Will you swear at it every time you have to go round it?  Sometimes it can look better if you plant just off the lawn to draw the eye further away.

thanks for the advice - you have a point!
