Tree Pruning Sealer Saves Lives

A Tree Pruning Sealer helps minimize sap flow and exclude moisture from wounds or injuries caused by pruning and trimming. And let's face it - they're all too common, and few monitor just how many trees die or are fatally injured by such accidents.

A pruning sealer encourages natural healing, and provides pruning cuts with a clean, professional appearance.

Fruit, shade and ornamental trees which are open to canker or systematic diseases can also benefit greatly from applications of a tree pruning sealer.

Many come ready to use, dry fast and can be applied during most weather conditions immediately after pruning.

The product is available in a variety of sizes ranging from 8 ounce bottles to one-gallon cans, including an easy-to-use aerosol spray. Cost is usually around $25 a gallon.

For additional help in protecting your trees from injuries caused by pruning, weather storms, or damage due to small animals or deer, you might also investigate using a wound and grafting compound.

Plant Trees Now

American Forests, a not-for-profit association based in Washington, has maintained the National Register of Big Trees for over 50 years.

American Forests uses a three-part formula—based on girth, height and crown spread to rate a tree by size and determine which is the champion — the biggest.

The current National Register lists over 800 tree species with a recognized National Champion.

But that is only a by-product of its work. American Forests works to protect, restore and enhance the natural capital of trees and forests.

"Healthy forests filter water, remove air pollution, sequester carbon, and provide homes for wildlife," it says. "Help plant trees to restore areas damaged by wildfire, where critical wildlife habitat has been lost, and to clean our air and water."

You can also learn how you can plant a tree in your backyard with the step-by-step rules of tree-planting listed on its site.

Black Walnut Tree Mysteries

The black walnut tree manufactures a substance that is a natural insecticide according to experts at the Texas State University in Austin.

American black walnut tress contain a tannic acid chemists call juglone. The reddish yellow substance leaches from leaves, and some believe exudes from roots, or transfers from branches and foliage to the roots. Tree physiologists agree that roots of other plants that come in contact with those black walnut tree roots die--even other black walnut seedlings.

Juglone is sometimes washed out of the still green walnuts during late summer or even autumn rains. The growth of plants 60 to 80 feet away are inhibited by the juglone.

The substance affects plants of various families.

Studies have found that tomatoes, alfalfa, potatoes, apples, blackberries, rhododendron, mountain laurel and pine trees are all affected.

According to a professor and extension forester at Iowa State University, juglone is known to repel various garden insects. Just by placing branches of the tree around the house and under furniture dog and cat owners are amazed to find that their pets have fewer fleas.
