I have a driveway lined with approx 200 7 year-old oak trees. They are planted only 2-3 feet apart and are now between 8 and 12 ft in height. What do you suggest I do at this stage? Are they too close to mature properly and should I remove say,four of every five? Is it feasible to transplant this number of trees or is it too daunting a job? Can you give advice on pruning lower branches to facilitate the lawn-mower? Many thanks!

They are much too close together to mature properly as big trees. Remove every second tree, or cut off and kill the cut stump with Roundup.
In five years, again remove every second tree, or kill it as outlined, and five years later, take out every second tree until they are about 10 to 15 metres apart. You could also take out two of every three to speed matters up.
Prune up the stems, removing small branches to leave a clear trunk. This can be to two metres when the trees are four to five metres tall, and to 3 metres when they are six or seven metres tall.
