Me and My family moved into our house 8 years ago and have a big oak tree in our front yard. we wanted to keep it there because A.) it provides shade and B.) keeps the house cool. But ever since we moved in we've had trouble growing things on that side of the yard. So we ended up renting a tiller and tilling the ground adding new soil, composts, etc. and we still have problems with growing stuff over on that side. 4 years back we had white jasmine growing over on that side of the fence and we believe our neighboors killed it, and now we have this trumpet vine that just appeared this year that took over that side of the fence, its killing my wife's Clematis and personally i think it looks ugley. Me and my wife have thought about it and think our neighboors kill the plants they don't want on that side of the yard. Any suggestions on any plants that you think we'd both agree on (her yard is mainly devils trumpets). and if there is any suggestions for ground covers or somthing it would be greatly apperiated.
