|In Hemenway's book , he mentions the cherry growers on Orcas Island plant caragana with their fruit trees.|
They claim the trees grow faster with caragana as the nitrogen fixer?
Anyone else tried that?

|I remember reading that and I found it pretty interesting. I've grown inoculated legumes in my orchard but never full size nitrogen fixing trees.|

|I have a cherry, bought at end of season sales.|
Will try to plant it next to the caraganas.

This plant is considered invasive in many areas, especially northern regions, as it escapes cultivation and has the potential to widely spread in previously pristine natural areas.

Thanks so much, Elizabeth Bella "
I found this entry under caragana arborescens, Siberian Pea Shrub, over at DavesGarden Plant Files.
I notice that many leguminous plants--such as kudzu are highly invasive. I suppose as Nitrogen fixers they increase ferility so as to make a cozy home for themselves so they can take over!

|Yes, Caragana is on our Invasive plant list.|
The ones I have growing are not spreading at all and they are several years old.
There are several different cultivars.
My favorite is the Caragana microphylia which has silver leaves.

|I have had siberian pea bushes (part of the caragana group) and they pretty much stay put. Unlike spirea that spreads like wildfire if you let it. I have a pruned caragana tree that sends up suckers within maybe 5" of the trunk but I just cut them down and they don't seem to extend any further. I planted an apple tree about 15' away so will be interesting to see how it does. Course, I have no comparison as the apple tree is new to my garden.|

|I think the recommendation for caragana and fruit trees, means the two are planted in the same hole.|
Or at least in close proximity.
