Its never a good idea to use fresh manure on any bed except in the winter
Much better to use mature compost
Since you have removed Lawsons Conifers you will find you will need tons of
compost to restore the soil condition as all conifers double strip the soil
of all nutrients and turn it acid

I intend to use it to rejuvenate a border from which we are removing
Laucon
firs.
Probably replace firs with hedging - pyracantha, laurel, escallonia etc
