We have just purchased the L shaped raised garden bed in an attempt to have a vegetable garden. We purchased some potting mix to go in it, but I am wondering what else should be in it to fill it up. I have read branches and things, but unfortunately we don't have access to these (unless I trim a few of the trees around but thought the branches had to be old and dry). Should we also place weed matting underneath everything ?
We are hoping to just grow seasonal vegetables, but are very new to gardening - particularly setting up a new one.
Thanks in advance for any assistance.
