Looking to spruce up the garden for the dog days of summer? Don't want to 'roid them out with a chemical fertilizer? Us either, that's why we use a nice organic fertilizer: It's worm castings which sounds like what it is, but really a bag of them just seems like dirt and if you mix in a handful to your container pots or into the ground they'll deliver some much needed nutrients to your plants. Your plants will reward you by looking nicer and you'll enjoy the garden that much more.
I had trouble finding these at Home Depot, so you may want to call your local nursery to doublecheck that they carry them. I ended up buying a big bag of Worm Gold Brand Worm Castings for my garden upheaval at the Marina Garden Center.
