Hey guys,
I've noticed a few discussions on this topic on several other sites but thought I would bring it up here again as I'm a recent victim of this problem in my garden..
I had 12 Robinia mop top in my front yard and had them removed and stump ground down 5 months ago ā they were established tree about 20 or so years old. I planted established Japanese Maples in its place shortly thereafter.
Little did I realise the root system was busy preparing it's resurrection's tactic.
Now over the past few weeks I'm noticing massive amount of little suckers showing up aaallll over the place. I should have poisoned the trees before they were chopped down. I just did not know this was a thing and the tree remover promised it won't come back again. Clearly, they were clueless.
Has anyone else had a similar experience and did you have any 'success' in keeping them at bay and eventually killing it? It seems like letting the suckers grow a bit, then then chopping and poisoning them is the best way to slowly get rid of it. But this will likely go on for quite a while I think. Digging down and poisoning the larger roots that came off the stump probably isn't going to do anything at this stage as the entire root system has started to do it's own thing so it wouldn't be effected by that I don't think.
What poison and what ratio of dilution is the best at getting to these suckers?
Any advise would be appreciated.
