Spend green on greenery (hey, it's for charity!)

If you're in the giving and the growing mood, consider helping out the nonprofit organization Earth Pledge. Right now, until March 10, celebrity autographed gardening kits are being auctioned off. The proceeds will benefit Earth Pledge's "Seed Blitz" program, which teaches urban kids about the value of growing and nature. The seed blitz reaches 625 schools in 25 cities across the country.

So if you're a fan of Felicity Huffman,William H. Macy,John Legend,Virginia Madsen,Dylan Walsh from Nip/Tuck, actor Tim Daly (Private Practice and many other shows like the very underrated Wings), the cast of High School Musical, among others, you can bid to purchase gardening kits autographed by one or all of them.

Log onto Clothes Off Our Back, which is another nonprofit that operates solely to host celebrity clothing charity auctions. It's hosting the Seed Blitz charity auction. Founded by actors Jane Kaczmarek(Malcolm in the Middle) and Bradley Whitford (The West Wing) Clothes off our Back helps fund a variety of children's charities by tapping into America's cult of the celebrity.

OK, by telling you all of this, I've done my good deed for the day. My second good deed will be not to try to grow anything for the rest of the week. House plants shudder when I come near them with a watering can. Gardens shrivel up and die when I walk by. Trees fall. OK, you get the point. When it comes to foliage, I don't exactly have a green thumb...
