We have Leylandii trees at the end of our garden which are about 20 feet high. However they take up a lot of room and are costly to have cut back every year. Also it is impossible to grow anything near them. There is a wall behind them aprox 4′ high.We are thinking of taking them down but the house which backs unto us is very near the wall so they would be looking directly into our garden and we would loose our privacy which we love.We are trying to find something which we can replace them with which will be as high or almost as high and not cost a fortune. The garden is about 40′ wide.Can you suggest anything that would be suitable – either hedge, trees or else some type of fencing which we could grow climbers on?
Other hedges such as yew, griselinia, pittosporum or holly are more manageable but will take some time to give you the height you require.
Your best bet is probably a fence, or to build the wall higher, depending on whose wall it is. You could also consider a pergola of some kind, upoin which climbers of various kinds could be grown.
