Here's a home brew to preserve the green and beauty of Christmas trees and to prolong the freshness of natural evergreen holiday decorations. To extend their natural beauty, mix a batch of this special holiday brew. First, go down to your local garden center and ask for miconized iron. Then add 1-quarter cup to 1 gallon of hot water. Also add 2 cups of light corn syrup and 4 teaspoons of chlorine bleach. This stuff is powerful and can stain carpets, so keep a plastic sheet spread underneath. Finally, trim an inch off the tree trunk and ends of stems, and add more brew as it evaporates. When the needles of other trees and greens are dropping left and right, yours will will be fresh and beautiful -- right through the holidays. And that's the On The House tip for today.
