I have a ten foot high tree stump covered in ivy. I wish to have something like a clematis to climb through it to give a floral display. is this possible?

You will first have to rid the area of the ivy without making the soil toxic. This means that you will have to pull up all of the ivy you can, and then pour boiling water over the area to kill off any remaining roots. Do this several times.
