I have hedges around my property that are now just masses of brush that are twice as wide and twice nearly twice as tall as they should be.
Lots of the plants in this hedge are L shaped. Where they scrape the floor before turning 90 degrees and growing upwards.
If I were to cut back to where the hedge should start in terms of width, I would be cutting into the bottom part of the L and getting rid of all the height of the plant and just leaving a little nub in the ground facing away from the centre of the hedge.
What should I do to try to save these hedges and if possible how to do so to keep privacy while doing so. I'd be willing to do multiple pruning sessions spanning a few years.
