Removing a ficus tree, especially a mature one, involves cutting down the main trunk and then effectively dealing with the root system to prevent regrowth. Simply cutting the tree down will not kill the roots, which store significant energy and can send up new shoots (suckers).
The most critical step after removing the main trunk is to eliminate the root system. The roots of a ficus are known for their vigor and ability to regenerate.
Killing the Ficus Roots
Even after cutting the tree down, the extensive root system will likely attempt to regrow. You will observe suckers, or new shoots, emerging from the roots in the surrounding area.
To effectively kill the roots and prevent the ficus from growing back:
- Monitor the area: Regularly check for any new suckers appearing from the roots.
- Cut suckers immediately: As soon as you see suckers emerge, cut them off cleanly.
- Apply herbicide to stubs: Immediately after cutting the suckers, paint the cut surface of the stubs with a potent herbicide. According to the reference, "The only way to kill the roots off is to cut the suckers down as they appear and then immediately paint the stubs with Round Up or Brush B Gon."
- Repeat as necessary: Continue this process whenever new suckers appear. The goal is to deplete the stored energy in the roots by removing the growth and then killing the connection points with herbicide.
This targeted herbicide application ensures the chemical is absorbed directly into the root system, maximizing its effectiveness. Repeating this process over time will eventually exhaust and kill the roots.
Here is a simple breakdown of the root killing steps:
| Step | Action | Key Requirement |
|---|---|---|
| 1. Cut Down Tree | Remove the main trunk | Use appropriate tools safely |
| 2. Watch for Suckers | Monitor surrounding area | Check regularly |
| 3. Cut Suckers | Snip off new shoots | Do this as soon as they appear |
| 4. Apply Herbicide | Paint cut stubs with product | Apply immediately after cutting |
| 5. Repeat | Continue steps 2-4 | Do this until no more suckers grow |
By diligently managing the suckers and applying herbicide directly to the cut points, you can successfully kill the extensive root system of a ficus tree and prevent its return.
