hi everyone, im on an errand of mercy for my friend, there is a large sycamore tree in her neighbours garden, just on the other side of her fence, i think i read on here that it is likely to take all the moister from her soil, everything she plants seems to die, can anyone suggest an inexpensive plant that is easy to manage that she can put there, she did plant a clemitis 2 years ago but it is still just a stem ha ha, any advice would be appreciated, thanks ps, the border is in front of an 8ft wall
