I've been reading both here and elsewhere on the web to come up with a list of good guild options for various fruit tree varieties. It seems there are more articles on apple tree guilds than anything else, which is why that list is longer.
Below is what I've come up with so far. All of the plants are listed with a tree that is a pairing someone recommended online. (so, for example, if someone said nasturtiums were good for apples, I didn't automatically apply that to the other fruit trees)
Also, these lists are by no means extensive. In fact, I've removed most plants that are extremely poisonous or invasive (I have kids and pets around).
I've toyed with the idea of doing guilds where every plant around the tree is edible, so that is what I lean toward, but have included a few that are highly recommended that aren't edible.
If you have any suggestions about what I've got (I definitely don't want anything that will bother the trees) or if you have additions to recommend (as I mentioned, I'm mostly looking for edible guild plants, but not always, and nothing that will take over the yard), by all means, I'd appreciate feedback.
