I am looking for suggestions to make a screen of trees. We have an ownership boundary at the bottom of our field which is 33 metres wide. When we aquired the field and our neighbours bought the adjoining land he made an earth bank which was approx. 5 foot tall which soon became covered in brambles and weeds. We didn't mind that it looked a bit "wild" as soon birds and hedgehogs began to use it, and a farmer used our field for his crops and livestock. Now the neighbour is building 7 houses in his garden, has demolished the earth bank and replaced it with a 3 foot bank which he is proposing to plant some hedging on the top. We would like to plant one or two rows of trees in our field to screen the new houses. We think they should be approx. 5 - 10 metres tall, with quite a dense canopy to help blot out the houses. The proposed trees won't cause any shade on his property as his houses will be behind the trees - any suggestions for species would be appreciated - with pictures if possible.
