Frequently Asked Questions
How far from my house should I plant a large shade tree?
To prevent structural damage, always plant large shade trees at least twenty feet away from your home’s foundation. For trees that develop massive, spreading canopies or possess aggressively spreading root systems, increase that distance to thirty or forty feet. This proper spacing ensures the mature roots will not compromise your foundation walls, and it prevents heavy limbs from hanging directly over your roof, significantly reducing the risk of storm damage.
Can I safely cut surface roots that are lifting my sidewalk?
Cutting major surface roots poses a severe risk to both the health and structural stability of the tree. Severing roots that are larger than two inches in diameter can open the tree to fatal fungal infections or completely destroy its structural anchoring, leading to sudden uprooting during the next windstorm. If aggressive roots from an oversized tree are destroying your hardscaping, you usually need to consult a certified arborist to discuss safe root pruning techniques or, in many cases, complete tree removal.
What are the best low-maintenance trees for a small backyard?
For confined spaces, you must look for dwarf varieties or naturally small ornamental trees that top out at twenty to thirty feet. The Eastern Redbud, Japanese Maple, and Kousa Dogwood offer spectacular seasonal interest, well-behaved root systems, and a highly manageable size. These trees provide excellent aesthetic value without dropping hazardous debris or sending invasive roots into your plumbing lines.
How do I permanently remove an invasive tree from my property?
Cutting down an invasive tree like a Mimosa or Quaking Aspen often stimulates the surviving root system to send up dozens of new shoots. To permanently eradicate them, you must cut the trunk down to the stump and immediately paint the fresh cut with a targeted systemic herbicide. The roots absorb the chemical, killing the entire subterranean network and preventing aggressive regrowth. Always follow the manufacturer’s safety instructions or hire a licensed professional for the application.
