Nature and Fallen Leaves

Wednesday, October 15, 2014 by

Not only do leaves make trees look beautiful, their importance in sustaining life on this planet cannot be understated. Their bright green appearance in the spring is an indication of the beginning of a new life cycle. In the summer leaves provide much needed shelter from heat and rain for wildlife and humans alike. They also serve as the vehicle through which trees produce their own food. Their dramatic beauty in the fall is simply unparalleled. In addition to all of this, properly used as mulch or compost they provide outstanding organic matter and nutrients to the soil called humus. Soils that have a high humus content, have abundant living biological activity to convert plant residues, leaf litter, animal dung and various biomass into stable humus. Humus gives the soil the ability to absorb...

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. Do not lower mower height, keep settings at...
