fence!
i think this is a really cool idea but concerned you might need a deeper box for herbs. my understanding is that they have deep roots and would need more soil.
just wondering – the list says only 2 4” x 4” posts? is this for the legs? if so, there are 4 legs – about 4 (foot high) x 4 (inches wide)! correct? and what is ‘hardware’ cloth – the screen?
