Our neighbours have some very tall trees planted right beside the boundary fence between our gardens. There is leylandii, beech and oak – all are very tall at least 30 foot. I was planning on making a flower bed beside this boundary fence, is this possible or will anything grow so no near these trees. Not sure whether roots of trees will affect plants growing near them.
Established trees will take the moisture, nutirents and light all around them, including on your side as they have rooted under the boundary.
Flowers will struggle, shrubs migh tbe a better bet, but they will need to totlerate shade and will need watering to establish them in their early years.
