Camellia and Mushroom Compost
I just spread 2 meters of mushroom compost on garden to then find pH level is 7 and not good for my gardenias and camellias. Do I need to pick it all up, a huge job? Or could I leave some down and mix it with some peat moss to try to neutralize it?

You do not need to pick up any of it. Just add some additional amendments to balance the soil. This article will help with that: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/raise-acid-level-soil.htm
