How to best utilize a bag of worm castings in the garden?
I have about an acre of gardens total. Need to organically fertilize the soil, things growing poorly. I can buy a 20 lb bag of worm castings for 25.00 (delivered) on internet. At this price, many bags is not affordable! I am wondering if it is best utilized by sprinkling a little at the base of each plant and mixing it in bit, or making it into a compost tea? I am set up with a garbage can to make about 20-25 gallons at a time. But I don't have a clue how many gallons of tea 20lbs.---about 1.5 cu. ft---would make. Maybe only 1 batch? I am thinking that the tea brewing process would make the bacteria and beneficial organisms multiply way beyond what was originally in the castings. If this is true, then "inoculating" the soil with the tea would be much better than "inoculation" it with the castings directly. Ideas? recommendations?
