Hello, I'm new to the forum and am wondering whether anyone has views about the potential weediness of tagasaste in urban re-veg areas? I have been reading lots and I can’t make up my mind. It is supposed to be very palatable to all types of grazing and browsing animals, from rabbits to kangaroos, but my concern is that in the absence of such animals, there’s not a lot to keep it down. I’m assuming the seeds will spread in bird poo? I read of a farm in permaculture farm in NZ where they ended up pulling them all out because they were too invasive. We are only 3kms from Merri creek, and I'd be devastated if I helped to introduce a new weed species to an area in which indigenous species are just re-establishing. I have been trying to look for indigenous nitrogen fixing alternatives. She oaks seem the best in that regard, but they grow too tall for where I want to plant them. L We have an area that I would really like to have screened off by evergreens to about 3m, but they need to be something we can keep quite hedgy. I’m currently thinking we might need to take the feijoa route. That will make one child very happy, but I loathe them and would prefer a nitrogen fixer if I can find one! Does anyone know if pigeon peas grow in Melbourne? Shrubs that size would be ideal. Thanks for your ideas. e.
