Gardeners' Notes:


On Jul 9, 2015, Rickwebb from Downingtown, PA wrote:

This is a common forest tree in many parts of the Midwest and East USA. It is also planted a lot in landscapes there, though usually as a cultivar since the 1970's. 'Autumn Purple' is the most commonly planted cultivar. It grows about 1.5 feet/year and lives about 150 to 200 years. It usually has 7 leaflets that are bigger and more rounded than the Green Ash, though there can be 5 to 9. The gray-brown bark is furrowed in a diamond-like pattern. The young branches have smooth grayish bark. The leaf scar, where the leaf falls off in autumn, looks like a smile. The autumn color is good of being bright gold or orange or red-purple. It is a good quality tree. It is susceptible to the new Emerald Ash Borer, but does not get killed as fast as the Green Ash does.

We have two of these trees that are at least 50 years old and planted by the first owners of this house from our neighbor's family farm. The are great shade trees, but both have developed Ash Yellows. We had them treated and fertilize with 10-10-10 in April and November. To prolong their life, we try to make sure they have good water during dry months.

The downside to this tree is the amount of small seeds late in the year. We also see lots of Ash seed weevils in September. Once we had Ash anthracnose after a wet spring.

Overall, a nice tree though.

This is a very interesting underused species of ash. If you select a cutivar instead of the type, you get interesting fall colors which range from royal purple to orange - red compare to Green Ash which is one of the most common planted ashes by far - in Minnesota 90% of ashes planted are Green Ash with Black ash popping up once in a while and they both have yellow fall colors. Black Ash often comes in from the wild. With the wild white ash, you kind of roll the dice - you can end up with yellow instead of other fall colors. Have significant disease problems which limits its uses.

The most valuable and largest native Ash. Uses include Furniture, flooring, interior millwork, tool handles, musical instruments, skis and oars.

This tree can get quite large 70' to 90' and is favored for shade plantings.

This particular ash is one of the tallest species, reaching as high as 80 ft.

Ash trees are great shade trees.
