Bare Root Trees Are Easier Than You Think

Planting bare root trees is a fun and economical way to have lush green trees on your property without the higher cost of purchasing established trees. Although it is not difficult to do, it is important to keep in mind some specific guidelines in order maximize your chances for success. By following these easy steps, you can turn your brown thumb into a green thumb in no time.
Carefully unpack the bare root tree from the container or material it came in. Be careful not to damage any of the roots during the unpacking process.
Set the tree into a bucket filled with water. Allow the tree to soak for 4-6 hours prior to planting. This will allow the roots of the tree to soak up water and not dry out during the initial shock of planting.
Dig a hole slightly larger than the diameter and depth of the tree and soil width. For example, if the tree roots and soil are 50 cm /19.6" wide, dig a hole 60 cm /23.6" wide to allow for maximum root spread.
Check to be sure there are no lar…

Cherry Trees in Atlanta Make a Superior Showing

After a dry and dull 2007, it looks as if this year's growing season is commencing with a grand fireworks display. Yoshino Cherry trees are blooming in one of the fullest and consistent displays in recent memory. Just about any asian cherry cultivar or hybrid is glaringly obvious right now. Even the sides of normally drab highway buffers are sprinkled with lavender and nearly-white flowers.

The Yoshino Cherry is the famous tree species in Washington DC, common on US Capitol grounds and around the Library of Congress. In 1909 and again in 1912, the city of Tokyo sent thousands of Japanese cherries to Washington. It is known as Somei-yoshino in Japan, a hybrid of unknown origin that was first introduced in Tokyo in 1872.

Atlanta blogger Judi has a weeping cherry ornamental that is in the spirit too.

Pine Tree Looses Needles Early; An Apparent Impostor

In the late 1990's, upscale neighborhoods in the urban center of Atlanta began to treat their cell towers to a bit of camouflage. Imitation needles and branches were affixed to lifeless metal poles. One of the first towers to become 'green' was located at near the intersection of Briarcliff and North Druid Hills Roads. So realistic were the well fashioned duds, that commuters exclaimed that they never realized that such a big Pine tree sprouted up behind the Burger King.

Now, almost 10 years later, it appears that the tree has dropped its drawers prematurely. Exposed for the sham that it is, this is one Pine that now needs a little dressing up again. Or have the Pine beetles become just a bit too aggressive?

White Blooms in Atlanta

For those searching for information on white blooming trees in Atlanta, there are several showy woody plants that are flowering right now:
Bradford pear trees are finishing, and now starting to push their leaves.
Wild pears are still flowering.
Dogwood trees are beginning to open up their flower buds, but this will take at least two weeks to get going
Star magnolias are finishing up.
White flowering cherry trees are just starting to open their flower buds.

Tornado Appears, Damages Trees, and Leaves

A tornado touched down in downtown Atlanta, sometime between 9:30 and 10 PM, Friday night. As the city's residents go outside this morning to examine what happened, they may find that their beloved trees have been damaged or even toppled. So far the blogs and news sources are reporting that many trees came down onto houses and cars.

Like the tornado of 1998, north of Atlanta in Dunwoody, trees will need to be cleared from roads and taken off houses over the next few weeks. Many more trees, that are still standing, have suffered partial or non-catastrophic damage. All tree owners should take the time over the next week to examine their trees for the following:
- A new, or aggravated, lean
- Broken, hanging branches teetering in the tree canopy
- Large cracked limbs still attached to the trunk
- Broken roots near the soil surface
- Heaving or mounding soil near the base of the tree
If there is any question as to whether these failures are hazardous, a qualified tree risk assessor should…

Pear Tree, Part 1

My son and I have been watching a Kieffer Pear tree around the 'hood. In a previous article I mentioned that this tree was to be our subject of study this year. The tree's buds have erupted.

The sepals and flower petals are clearly visible.

A few young leaves can be seen as well.

The creamy white color of the petals will develop within the next few days.

Greenspade Shovels Up Some Unique Information

Greenspade, a horticultural and tree blog, deserves a look. Although the author is not local, Atlanta tree enthusiasts will find the site interesting. The author, Chris Welch, puts a new twist on blog presentation by organizing article titles as horticultural definitions. If my explanation leaves you puzzled, then visit Greenspade and check out the format. The photography is very good. Graphic elements are pleasing.

Trees Fall, Drought Blamed Yet Again

The flurry of storm activity over the past week has focused attention on big trees - especially the trees that have fallen. News outlets have produced a stream of reports mentioning the damage caused by tree failures. The AJC, WDUN, The West Georgian, WXIA, and WGCL, all ran mainstream stories just in the past few days.

Because the drought is still in people's minds, it has become a catchall scapegoat for a number of tree-related problems. It is easy for people to grasp for a connection between drought stress and trees falling, but it is somewhat rash to do so without fully analyzing each case. Catastrophic tree failure is an event that involves the interaction of forces upon a very complex tree system. There are few resources and tools available to diagnose drought-related failures.

Of the catastrophic failures that I have recently observed in Atlanta, drought has not been the primary or secondary cause. Rather, each case involved serious structural problems such as decay. …
