I think maybe some sort of elevation or having a box with soil set up in the air or wall garden that anticipates the sun movement would be able to help you plant.

Only one part of the yard gets full sun all day (we had to remove a shade tree that happened to be a widowmaker) and that's where the chickens live (because it's also conveniently enclosed, that's just how the yard works with where the buildings are).

The rest of it is covered in shade trees. The only way anywhere else will get a decent amount of sun is to remove the shade trees asnd that's not an option.

We have considered trying to move the chickens to the shady side but there isn't an easy and/or aesthetically pleasing way to do it.

Wall gardens are definitely an option, we just haven't gotten around to rigging something up (not trusting hanging anything off the fence as it's probably super six).

I used to work on a herbal garden until I didn't have the time to maintain it and snail ate up everything :/

Drat :< Maybe take it up again?
