We do some small scale composting on the site at Bow Point Nursery. We bring in horse manure / sawdust from a horse stable just down the road from us. We use the composted material for maintaining our soil in the nursery. As we harvest plants, we put down a layer of compost before we replant.
We do offer compost for sale for those who need to replenish or rejuvenate their soils (or dirt, depending on your situation).
Cost is $40/ cubic meter.
