the thought that you're lucky that out Northwest neither Home Depot or Lowes carries red mulch poses one thought when I give you something to think about........the studies at horticultural institutes has come across something of interest. Apparently when you mulch TOMATO'S with red mulch, they produce more fruit, ripen earlier and have more flavor. That's what I read in one of my horticultural magazines. And yes, sometimes I DO believe what I read. (I only read Horticulture, Fine Gardening and for a bit of curiosity, Garden Design and a few other garden magazines that peak my curiosity. I subscribe to the first three, with a gift of Garden Gate coming from a friend, and the occaisonal magazine that catches my eye. Don't know why red mulch has this effect on tomato's, will have to search the results of this to clarify this better. Or at least give you an issue to do your own research. Or maybe Paggers can fill you in on this tidbit or set me straight.
And I never forgot about the name of the "Mexican bamboo" I was trying to identify for you. I've not located the name yet...................... madgardener persistant as always.
