Re: removing oleanders
Oleanders are a very hardy plant and with some selective pruning could be brought back to beauty. Since you are allergic and keeping the plants is not an option, simply cut them down and have the stumps removed. I am uncertain if grinding the stumps is an option due to the manner in which these things grow, I would also be leery to leave the chip debris behind if you're allergic to the plant.
