Hi gang,

My question is this. Is there enough soil mass in a
28 foot-long 10" wide x 12" deep container to support 9
or 10 cedar shrubs placed 30" apart?

In my opinion, no. At least, not long term, without laboriously removing the
trees periodically, root pruning, trimming the foliage, and replenishing the
soil.


How durable would such a container be, assuming I used
pressure-treated (P.T.) wood? Would 1/2" diameter holes
drilled near the bottom provide adequate drainage?

Very durable, however care would have to be given to cupping and splitting
of the wood, especially near the fasteners.
