Is this in granular form or crushed shell? How much would I need for my 20' by 40' garden?
With Neptune's Harvest Organic Crab Shell, you will use 3 lbs. per 100 sq. ft. in a garden. To treat an area of 20' by 40' you will need 40 lbs. of the product. It is made from crab shell and crab scrap. A 12 lb bag will treat 480 sq. ft.
