[Pil-pc-oceania] fruit tree guilds

[Ben Elms]

Hi there.
Im looking to improve/create guilds round our new and old fruit trees. 
This is a drylands temperate climate. In particular looking for small 
nitrogen fixing plants. I am considering lupins.
We already have many trees with comfrey and fennel  and a few bigger 
nitrogen fixing trees  in the vicinity. Will also sow some carrots etc. 
and some Tansy round the peach trees. and so on.
Any ideas or experiances out there.

Also does anyone have any clever solutions to suckering fruit trees  in 
particular plum and cherry.
many thanks
Ben
