Disease Resistant American Elm Shade Tree
- Excellent Form
- Native Tree that Grows Quickly
- Wildlife Tree Provides Nests for Baltimore Orioles and Other Songbirds
- Now Shows Resistance to Dutch Elm Disease
- All Shipments Protected with Plant Sentry™
The elegant shade tree, American Elm (Ulmus americana) needs a boost to fully rebound back from a terrible tragedy that happened during the 20th century. Unfortunately, some of these trees fell victim to phloem necrosis, otherwise known as Dutch Elm Disease. There were multiple factors that played a part, including three varieties of elm bark beetles and native leaf beetles and a fungus.
Ironically, the overuse of Elm trees as closely planted street trees also played a role to spread the disease. Without diversity, the "monoculture" of Elms growing tightly together caused problems. By the 1970's, an estimated 77 million American Elms were lost to this disease.
However, there is really good news on the research front for the gorgeous American Elm. Because not all the trees were affected, the industry has now identified natural occurring cultivars and seed sources that show resistance to the disease.
There has also been a hunt to find resistant hybrid crosses. Now, both seedling and hybrid selections of these magnificent trees are suited for almost every part of the United States. It's time to bring the American Elm back!
And why not? After all, the American Elm is a commanding deciduous tree with a beautiful shape. It's such an impressive shade tree with a lovely, rounded oval crown.
This tragic story reminds us how important it is to protect online plant shipments against invasive pests. Nature Hills uses Plant Sentry™, an online database that blocks shipments in and out of restricted areas. We follow all federal, state and local regulations to keep you and your communities safe.
Nature Hills won't ship trees into or out of areas where Dutch Elm disease has been reported. In areas of Dutch Elm Disease, check with your local Ag Extension agency to see if one of the disease resistant hybrids may be a recommended substitute.
American Elm tree is gorgeous legacy to leave to the future. It's well worth the fight to return to this majestic and useful tree for your community in the right areas.
How to Use American Elm Tree in the Landscape
The American Elm was one of the most popular shade trees used in cities and home landscapes throughout America for over 300 years. This stately, perfectly formed tree has been a picturesque part of the North American landscape and it's time to reestablish it once again.
Can you imagine how many children and grandchildren have played underneath wonderful Elm trees?
American Elm provides ornamental interest for every season. The six inch deciduous leaves are highly textured and have cute toothed edges. Their dark green color is a vibrant addition to summer surroundings.
Small green flowers form in spring, and although you're not likely to notice them, butterflies and other pollinators of your yard certainly will. Invite these "flying flowers" to your yard to add enormous appeal. Birds such as Baltimore Oriole prefer nesting in American Elm.
The American Elm is best used as a specimen shade tree in large areas. It's wise to plant street trees at least 20 feet apart (measuring from trunk to trunk) to give each root system plenty of room to develop as an individual tree.
In the fall, American Elm yellows to a pleasing, mellow autumn shade. They conveniently drop all their leaves in a short amount of time. This makes for an "easy fall cleanup", which is a nice feature you'll appreciate as you prepare your yard for winter.
This Elm shines, even in winter. Even during the cold season, the dark grey and deeply textured bark of American Elm gives you something interesting to look at in the winter landscape.
#ProPlantTips for Care
American Elms will grow to varied sizes and shapes from vase-shaped to oval canopies. In the hotter climates, like Florida, the American Elm grows less than 30 feet tall.
Don't crowd this tree. You should allow plenty of space for the American Elm to receive maximum sunlight and air flow through the canopy.
Though tolerant of short periods of drought once established, the tree requires good drainage. American Elm is adaptable to many different soil types and climates if good drainage is provided.
Watch to see if your soil holds puddles after a rain. If it does, plan to create a raised mound 18 inches above the original soil line. You'll plant directly in that mound, which should improve the drainage.
In extreme summer temperature zones, add a thick layer of mulch all around the tree. Don't allow mulch to touch the trunk of the tree. Mulch over the root system will keep things cool. where occasional extreme summer temperatures are the norm.
Don't prune your tree from April to August. Instead, wait until the dormant season to do any required pruning.
New disease resistant American Elm are hardy trees that are tolerant of short periods of drought and urban conditions. It won't cost you a lot of time or effort to maintain and will provide many years of shade and beauty for your yard.
