Why Leaves Change Color

Tuesday, September 23, 2014 by

Every autumn we revel in the beauty of the fall colors. The mixture of red, purple, orange and yellow is the result of chemical processes that take place in the tree as the seasons change from summer to winter. During the spring and summer the leaves have served as factories where most of the foods necessary for the tree’s growth are manufactured. This food-making process takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green color. This extraordinary chemical absorbs from sunlight the energy that is used in transforming carbon dioxide and water to carbohydrates, such as sugars and starch. Along with the green pigment are yellow to orange pigments, carotenes and xanthophyll pigments which, for example, give the orange color to a carrot. Most of the year...

6 Fall Gardening Tips

Monday, November 11, 2013 by

Year-end garden tips 1) Leaving perennials standing and not cutting them back may help to protect the crown. If you mulch, go ahead and cut them back. 2) Rake fallen leaves from grass. Leaves left on lawn over winter will smother and kill grass. 3) Plant spring – flowering bulbs as long as the ground is not frozen. 4) Protect evergreen trees and shrubs with an additional watering sometime this month. Consider whether to protect the plants with a burlap screen to ward off salt-laden street plowings or to shield the plant from a south face where sunny days may warm the plant enough to begin breaking dormancy too early. 5) Continue mowing the lawn until growth stops, typically when temperatures are below 40 degrees consistently.

Thursday, August 2, 2012 by

Article by National Gardening Bureau, Inc. When the trees begin to show fall colors, your garden can too. Unless you live in a mild winter climate, you may not have thought about planting for a fall harvest that can continue even into the winter. Now is that time to plan for fall planting.

In season, they are fabulous, especially cut-and-come-again greens like leaf lettuces, arugula, mustard and others.
