brambles in guilds
I purchased the book Gaia's Garden and read it cover to cover about a week ago. I'm hooked on the concept and want to begin planning and implementing the ideas on my property. I'm working on ideas for a Black Walnut guild since I already have one on my property and two next door right near my tree. I've read that black raspberries will tolerate the juglone so that is one thing I'm planning for the shrub layer. What I'm wondering is how and how much do you control the spread of brambles in a guild or food forest. I have two year old raspberries in another spot and they are already threatening to out grow their space.
