I have a wooden herb rack which is attached to the wall and I’m about to plant my herbs. Should i line the rack with a liner of
some sort? I have drilled drainage holes so the herbs wont be in standing water.
I think it makes good sense to use landscape fabric to line the bottom. This helps soil from falling out the drainage holes. I hope the following article has useful information: https://www.gardeningknowhow.com/edible/herbs/hgen/creating-an-herb-wall-garden.htm
