we drained an area along laurel hedge with shores last year as was water logged but its showing no signs of recovery yet...do you know how long it should take to green up and start new growth again? Its about 4 years old.

I have acquired a load of old used mushroom compost and don't know which areas of my garden it is ok to use in or what ratio to soil to use it? I have raised beds, spuds area, greenhouse, fruit trees and ornamental garden
