You really have two choices, you can either let the wood of the planter b=

Assuming the planter is sitting outside, its going to get wet when it rai=

The construction is simple, battens on the bottom of the planter for the =

have them extend down through the bottom of the planter.

Does anyone else feel that these planter boxes are being overengineered?

I just use some old redwood fence boards, drill a couple holes in
the bottom, and add some dirt (hardware cloth over the holes to keep
the dirt in is optional - a thin layer of stones at the bottom generally
suffices).

It will eventually[*] rot, in which case I take another old fenceboard
and build a new one.
[*] decade, decade and a half around here.
