The #hivegarlic collective will be strong with your planting! Looking like all 1000 of mine are coming up.

One thing I make sure to do each year is save all the ashes from my fireplace and fire pit and then spread it out over the garden before a tilling. You have the burner, does that make ash or is it a super clean burner? Probably not enough for the acreage you are looking at but can be great where needed.
