What I have found most effective is to hack and squirt slightly diluted RoundUp into the cuts. I essentially try to ring-bark the tree and dose the cuts with Round-up so the tree has to suck it in. It seems to work OK in the long run although you don't see immediate results.
I cleared along the property line to put up fencing and dosed the stumps with RoundUp. That was done over the last 2 to 3 months. Just today my neighbor pointed out a stand of guava on his side that had died. This must have been due to the shared root system since I never applied anything to those trees and they were a good 6 feet over the property line. He was concerned that he not lose any more trees. It makes more sense when you understand that they have a nice house with beautiful landscaping and I have a shipping container and at least in the short term am practicing a scorched earth policy directly along the fence line. The guava trees provide a screen until their podocarpus grows in. I myself am looking for something to plant along the fence that will restore the privacy while not being guava.
