The Tree of Heaven Thrives Almost Anywhere
Not everyone considers it heavenly. It's not really an ugly tree. It just loves that God made it to bear seeds to reproduce itself and the Tree of Heaven does it with enthusiasm. A remarkable number of those seeds sprout and become new trees. Most of those trees aren't welcomed. They tend to move in and take over. If you try to chop down or cut off a small tree, it will multiply even more by producing a multitude of suckers.
What you see above are just a few branches hanging over a shed in the Templeton Community Garden. I'm afraid if someone doesn't so something soon, there will be a forest of Trees of Heaven. The babies are already popping up all over where they aren't wanted.
Here's an example. The fence you see below separates the Templeton Community Garden from the property around it. There is a majestic oak on the other side of that fence. Do you see what's growing under the oak and on both sides of it? Yep! That's a Tree of Heaven forest waiting to grow up. The Tree of Heaven seemingly can exist and grow without much sunlight, so the shade of the oak won't do much to thwart it. It hardly even needs soil.
The Tree of Heaven Is Far from Heavenly
For one thing, it smells. That's right. The base of the leaves have oil-bearing glands. If you rub them, you probably won't like the odor. The flowers have the same "fragrance."
The tree is also destructive. It can grow from a crack in a sidewalk and destroy the foundations of buildings. It is so invasive that it threatens native plants and agricultural crops. The seedling below is very close to the raised bed where the tomatoes are growing.

You don't want Tree of Heaven growing anywhere near your garden is because it has a toxin in its bark and leaves that will kill other plants around it. I wouldn't put the leaves in your compost pile.

What Does the Future Have in Store for This Raised Bed in the Community Garden?
We have seen how quickly Tree of Heaven can spread. We also know the toxins in its bark and leaves can kill surrounding plants. It would appear the Templeton Community Services District needs to pay more attention to the maintenance of this garden area. Not only does it play host to the Tree of Heaven, but we've seen in a previous post that poison oak is also growing just inside of its fence on the south side.

The tomatoes survived proximity to the seedlings this year. By next year the tree will be much taller if not controlled now.
