We have an Oak tree that is to close to our septic tank and now we have to replace the tank, the roots are growing on top of the tank. I am unable to afford $2800 to remove the tree. As much as I hate to, I need to "kill" the tree. I feel I have no choice as it will continue to "look for water" which will lead it to the new tank. My concern is that once I do this, what becomes of the tree during a hurricane (Since we live in Florida)? Can we slowly cut the branches for proper disposal? Thank you Mrs. Mann
Most oak trees will continue to live and put out new root growth until the tree is completely removed, including the stump, or until it is poisoned with herbicide.
So even if you slowly cut and dispose of tree parts and whittle it down, it will still be a potential for invasive roots as long as the tree is alive. Even a cut stump may re-sprout and keep growing roots unless ground or grubbed out or poisoned.
I would rather be telling you how to preserve your tree and keep it healthy, but I understand your situation and budget constraints for removal. I don't know the size of the tree or the logistics, but I would recommend that you consider having the tree felled and the stump sprayed immediately after the final chainsaw cut, around the outer rings of the cut surface, with RoundUp Pro Concentrate or generic brand (glyphosate 48 to 50%) diluted with equal part water. The material will be taken in and translocated throughout the root system for a complete kill. "immediately" is the key word, don't delay.
You can then cut up the fallen tree parts for disposal.
Another way to save money on the tree removal is to have a tree service fell the tree and chip the brush and small limbs on site or in your driveway to use as mulch. Also you may have them cut the wood into firewood lengths and leave it on site. You can stack it yourself for firewood, or give it away, or haul it later.
The hauling and disposal fees are sometimes a large part of the removal cost. If you keep the material and handle clean up yourself and hauling if necessary you can sometimes save 30 % to 50% of the cost for complete removal.
Hope that helps, Don
