Tree Review Part 3


Besides covering more recommended trees for North Texas, I wanted to mention a source of information on planting and managing trees. It also covers some of the most fabulous trees of the world including some I've had the pleasure of helping, including the National champion pecan tree, the fastest growing ginkgo in Texas and the Nellie climbing trees. It's called the Fabulous Tree Slide show and it's free. Go to the top right hand corner of or straight to this link.


Texas ash leaves are darker green in summer than other ashes and the brilliant fall color has a wide range every year


Texas Ash (Fraxinus texensis) is the most plentiful ash in Texas. It may be a subspecies of White Ash, Faxinus americana but it is far superior to every other ash in many ways. Some in this industry advise against all ash trees; this one is different. It has dark leaves in summer, gorgeous fall color that ranges from yellows to reds and purples and none of the problems that Arizona and green ash suffer.


Mexican sycamore is a better choice than our American sycamore


Mexican Sycamore (Platanus mexicana) has large distinctive leaves that are medium green on top and dramatically white on the underside. Foliage changes to yellow or orange in autumn if weather cooperates. It is a faster grower and has far less disease issues than the American sycamore.


The graceful shape of ginkgo leaves is unique to this prehistoric tree


Ginkgo (Ginkgo biloba) is prehistoric and one of the most unique trees on earth. It has a reputation of being an extremely slow grower but not so much under the organic program. Life in the soil is the key. The graceful foliage design is unique to ginkgoes. The name ginkgo is from the Chinese word meaning silver fruit. The species name biloba refers to the two-lobed leaves but some leaves have only a single fan shape.

Pecan (Carya illinoinenis) is the state tree of Texas and a great shade tree choice. Native trees and hybrids with small nuts have been said to be the best choices. They probably are as far as landscape use. However, research by Dr. Joe Bradford in Hamilton, Texas, showed that 'Desirable' was much more nut productive than 'Caddo' and other small nut trees. Pecan trees are a little messy, dropping bark, twigs and other debris, but they grow beautifully in all soil types and can provide some delicious nuts.


To ensure a productive pecan crop with few insect and disease troubles, use a basic organic program that includes organic soil building and foliar feeding with Garrett Juice plus additives of garlic oil for pest prevention. Zinc is recommended often but rarely needed in an organic program. Buffered and proper levels of zinc exist in many of the natural organic products including fish, seaweed, Garrett Juice, humates, etc. Plus the organic program allows tied up nutrients in the soil to be released and made available to the plants.
