Yes on the topic of that horrible wood mulch that everyone uses... even at the Horticultural Center where I volunteer as the weekend Librarian they use the stuff. I was really sad to see that they had a huge pile of it there this past weekend.
Oh well, I guess there is nothing we can do but pass on the good word of mulching leaves, grass clippings, seaweed and the like. And by the way, for those people who are reading this thread:
If you make a nice mulch from the above listed ingredients... it does keep the weeds down quite nicely and it enriches the soil making your plants grow better, bloom more often, have more vibrant blooms, the edibles will tast better and less refuse will end up in our land fills. It's a win win situation for plants, people and the environment.
