Martin Crawford of the Agroforestry Research Trust talks about the Forest Garden he planted at Schumacher College, Dartington, South Devon, United Kingdom over 14 years ago.
Ive come up four nitrogen-fixing perennials that I want to add to
the Minnesota garden next year. These will all thrive on poor soil.
The Silver Buffaloberry
I envision a massive hedge of these across
the southern border of the garden.
Maybe alternating with serviceberries and hazelnuts.
The Sea Buckthorn or Seaberry (WHAT A FIND)
These will hold on to their berries throughout the winter and feed
local bird populations, and are just loaded in vitamin c.
And it will IMPROVE your soil..plant your fruits and nuts near these
for a perfect synergy, they will both do so well together.
The Siberian Pea Shrub
Id like to make a dense hedge around the future poultry area.
How perfect would that be? How intense would that soil be?
The Goumi Tree or Shrub, depends on pruning
Hardy at about -10F, so this would have to go in the greenhouse dome.
I should do paw paw, goumi, then paw paw again in a new greenhouse.
There might be room in there for some dwarf seaberries,
but otherwise its short groundcover and beneficial insect plants.
Lots of Nitrogen-fixers in that mix for sure.
Ive got kiwis WAY too close to each other so that will be interesting.
