In a few weeks my beds will be empty
I have 10 at 4' x 14'
I can get some bags from the local stables
? If my bags are normal builders merchants bgs how many will I need pls
? How long before I need to sow / plant should I spread it
? Do i fork it in or leave it on top
? I have 3 beds that need gypsum to break up the clay so what do I add first on those beds
