Hi, Great video, many thanks for sharing.
I'd like to ask at what stage from planting time can you start cutting it back for mulch (chop and drop style)?
Also, it is said that it needs specific rhizobia strains of bacteria in order to fix Nitrogen so, if one is not sure whether these bacteria are available in the soil where the tree is intended to be planted, yo can go to existing robinias stands and collect the soil underneath, because this is supposed to include the right NF bacteria. The question I have here is: how do I know that those already existing
trees will have the right bacteria? Because they may have also grown without those bacteria in the first place?
Or does this mean that the tree can only grow if those bacteria ARE in the soil otherwise they just die without ever becoming adult trees?
Cheers
