  St Giles Church Blanche Lane South Mimms Potters Bar Hertfordshire EN6 3PE

  A1: x3 large ash tree in the grounds of the church yard, the three trees are at the rear gardens of 85 and 89 Blanche lane. The trees are approximately 70 ft high, there is no plan to reduce the height of the trees they would like the lateral overhanging branches reduced by approximetley 2-3 meters in length cut back to suitable growth points, still leaving a good 2-3 meters of the lateral branches in place. Due to the trees location within the churchyard it would be far easier to view them from numbers 89 and 85 Blanche Lane because of the dense undergrowth (number 85 has a side access to the left of the property for access)
