Gardeners' Notes:


On Apr 4, 2021, Beetreeguy from Gordonsville, VA wrote:

This is the most invasive tree in Virginia. It pops up anywhere the soil has been disturbed, and pretty much any treeline. Its competitive advantages are prolific seeds and fast initial growth. Its weakness is that it's not quite tall enough to compete with tulip poplars or oaks if the forest is allowed to regrow undisturbed for fifty years. And yet they will persist. I cut one down years ago, and there are still seedlings in our yard undeterred by mowing. This tree can also ruin a honey harvest if your bees collect too much nectar from the disgusting flowers (it's an odor I wouldn't describe in the presence of kids). The only reason I can think of to plant one is if your yard was recently strip mined for coal and nothing else will grow.

In 1966 while exploring wild lands near Kentucky lake, I came upon an unusual tree with compound leaves that when crushed reminded me of peanut butter. Tree of Heaven I deduced. I found a young one and planted at my childhood home in Nashville TN in 1968.
Since the 1960s the forestry people have been preaching that this is a horrible and aggressive species that is taking over our native forests. So I examined and evaluated every forest I visited the next 54 years (its just what I do, smile). After about 40 years it was finally clear to me that the foresters were wrong, in TN and KY at least. The tree seems to thrive in bad rocky sites that have been disturbed by development, like roadsides. But when you enter the forest, it just simply cant compete and regenerate very well ... read more

We manage our own property, but without a community effort, it's hopeless.

Although the tree is considered an invasive and is capable of taking over areas where established, especially disturbed areas, there are wildlife benefits. Large patches or groves of these trees provide an ideal location to create a cavity nesting sanctuary for birds. I have gone into these groves with my chainsaw in the winter and will double band girdle 10 to 15 of the larger seed producing females. They will die rather fast, (one growing season) and will create snags that are quickly utilized by many cavity nesting birds. I viewed a Wood Duck actually using a natural cavity as a nesting site in an Ailanthus tree this past spring.
The snags created seem to last 5 to 10 years before they decay enough and fall to the ground. I will revisit these groves every 3 to 5 years and girdle... read more

Fortunately, buying and selling this plant in my state is illegal due to the havoc it's created in the ecosystem. Unfortunately, its already so prolific that it's taken over large areas and killed off many native species. (The horrible rotting-peanut smell is an herbicide it produces to inhibit competition) But for such an aggressive, rugged species, it's an extremely short-lived tree, living roughly 20 years on average and rarely over 50 years. It compensates though seeds that almost always root and suckers under the ground. Seedlings are fairly simple to eradicate, but the suckers are much more difficult.

There may be a way to control this plant, but before I mention that, consider 3 problems. First, cut the darned thing down (leave about 4' of "trunk" but no foliage--see below) before it makes seeds. 2nd, be prepared to pull seedlings growing from old seeds already in the ground. 3rd, it will spread by lateral budding from the roots.

Now for control. This "tree" seems to have very shallow roots, that is, no tap roots. The entire root system (all of the trees may be connected to one another) may be limited to a depth of less than 2'. You can dig down about a foot to the main roots, loosen them, and pull the "trees" out of the ground. Cutting the "trees' off at about 4' and removing all foliage a while before doing this weakens the roots and gives some leverage with which to w... read more

It is not a "control issue" any more than reducing polutants which we have wrecklessly unleashed into the environment.

Young trees are defoliated by the Ailanthus webworm but always revive. Some must be nearly 100 feet which earns them the name tree of heaven since it towers into the sky. Certainly nothing else heavenly about it. I think Ailanthus is a more appropriate name. Not just a city weed tree. It is just as bad in the countryside. Only a fool would plant one of these.

The Chinese Tree-of-Heaven or Ailanthus is one of the most invasive plants in the U.S.! It forms virtually solid, standing thickets like bamboo, crowding out native plants, by propagation and huge seed production! The seedlings and young trees are about the most invasive plant I've ever seen!

It can grow anywhere: healthy native upland hardwood forests (both adult and young trees), along streams, rivers, and creeks, along roadsides, fences, in vacant, weedy lots (especially!), in open areas, in small corners of space around homes or buildings outside, EVEN IN CONCRETE CRACKS AND IN CRACKS IN BUILDING WALLS!

An awful, awful plant that destroys native forests and can destroy your landscape, if left unchecked. One of the most invasive species on earth, only good in China, terribly stinking.

I have never noticed quite how invasive this tree is until I went for a car ride one day and observed it growing in 9 out of 10 of all the ditches, unmowed lawns, sides of the roads, edge of the woods and in fields.

I have a couple of these trees in my backyard at the wood line but for some reason, there is only three trees and it stays only three trees. If I see any volunteers, I will definitely not hesitate to pull them up, though. Removing the mature trees would be quite expensive.

The seeds are easily spread by wildlife, birds in particular, and I have found one seedling in the front yard. I have not noticed the trees giving off an offensive odor except for an odor reminiscent of peanut butter if I get close enough to whiff the leaves.

The name Tree Of Heaven comes from the rapid growth it produces....hence, it reaches Heaven faster than other trees.

I never use toxins but am willing to make an exception if it will get rid of this tree. I dream of harmless fruit trees.

It cannot be stated strongly enough that Ailanthus altissima is a very invasive tree under the right conditions and is a major threat to native forests in some regions. The worst I have seen is in central Tennessee, on rich, moist humusy soils over limestone, where Ailanthus is very common even in the interior of mature forests in natural areas. When a large canopy gap is formed by the death of a mature tree, Ailanthus can seed in to the gap and impede reproduction of native species well as spreading by suckers to form dense thickets. I would hope that those in rural areas surrounded by native forests would eradicate this tree from their property if possible.

Definitely not something you want to bring to your yard. If you are in an area where you need a fast growing windbreak, this might be your tree, but that is the only use for it I can find, although I never noticed the smell. I have one huge one in my yard, and several million babies. Drought doesn't bother it, since we've been in drought for several years. The seeds are sprouting in the garden where everything else burned up, soil temperature 127 degrees on the thermometer. Cold and snow don't bother it either, I am zone 5, altitude 7000 ft.

In my opinion, the Tree of Heaven is actually a pretty nice tree to have. I can not understand why people would say that the blossoms smelled terrible because they really dont seem to smell that bad.

Also, it even appears that the Tree of Heaven seems to be slightly stronger and more flexible than the Silver Maple. On July 5th, 2003, there was a microburst where I live, and from the way my backyard Tree of Heaven was blowing around, that wind had to be in excess of 65 or 70 miles per hour, and no more than 1 or 2 small twigs were broken.

Even though this thing is trying to take over my yard, I have to give it a neutral because it actually is a nice looking tree and grows really fast.

You cut the plant off at the base and IMMEDIATELY brush the solution directly onto the cut with a paintbrush. I really give it a good soaking, and so far, none of the plants have come back in the treated areas. Keeping my fingers crossed.....

Luckily, it is in a part of my yard where it does not drop leaves or sprout other plants, so other than the putrid smell in the otherwise lovely early summer evenings, and the heavy shade it makes, it doesn't bother me. I am going to leave the large ivy-covered stump to provide habitat, although the stump will be poisoned to prevent resprouting.

Do not plant this tree - it will ruin your summer evenings because of the stink.

Update September 26, 2007

The mature wood, as others have reported, is actually decent firewood. It burns very hot and fast, and lights easily.)

Acknowledging what others have said about medicinal properties. I haven't used it, but I'm finding that the homeopathic community has been using it. Don't try it unless you know what you're doing--REALLY know.

Knowing about these trees has become something of a hobby for me since moving in among them 5+ years ago. So I pay attention to oddities and patterns.

Today, as many times before, I heard the buzzing of zillions of bees around these trees. At first, I thought it had to be flies, but on inspection, it was indeed bees. There are no flowers on these trees at this time of year. What was attracting BEES? Why were they landing on the leaves?

Well, folks, these bizarro trees have some kind of gland on the leaves themselves, that exude something the bees are interested in!

I'm adding some photos, closeups of the leaves.

This tree grows like a reed, then becomes a tree. At an place in the tree, it can return to reedy growth. Weird stuff.

I have to give the tree credit as a survivor. I also acknowledge it has some uses. But that doesn't make it any less invasive or troublesome.

A rapid growing deciduous tree that can reach 80 feet or more. In late spring, clusters of small, yellow-green flowers appear near the tips of branches. Seeds are produced on female trees in late summer to early fall, in flat, twisted, papery structures.

All parts of the tree,especially the flowers,have a strong, offensive odor. This is a prolific seed producer, grows rapidly, and can overrun native vegetation. Once established, it can quickly take over and form a thicket. The root system is aggressive enough to cause damage to sewers and foundations. Should be considered a weed as once it gets started its impossible to get rid of.

Since I really can't see anything good about this tree wonder how it got the name Tree of Heaven...
