In general, trees should be planted no closer than 15 to 20 feet from your foundation. For larger trees with far-reaching roots like maples, oaks, or poplars, a good guide is to plant as many feet from your home as the tree’s height is expected to reach at maturity. Some trees, like elms and willows, should only be planted far from where their roots may encounter sewer or water lines.

For safety reasons, leaning trees are best removed by a professional, as they may often tear away from the hinge, causing you to lose control over where the tree falls. If you choose to cut down a tree leaning slightly, avoid cutting off root protrusions before you start. Make your hinge a little longer than usual by cutting it deeper (up to 30% of the diameter) and applying a wedge into the felling cut on the side the tree is leaning. Stand away from the direction the tree leans while making your felling cut.

It's easy to misidentify trees that appear to be maple trees due to similarities in leaf shapes. Sweetgum, sycamore, and yellow poplar all have leaf shapes and appearances similar to maples. The fact that around a dozen maple tree varieties exist, only about half of which are considered common, makes misidentification an often typical occurrence.  

You’ll have to balance up the cost, the value of the tree (sentimental or otherwise), and the risk factors. An experienced arborist will help you understand whether transplanting is likely to be successful. The cost and hassle of transplanting a large, well-established tree are often not worth it, especially if the species is fast-growing and easy to source. The decision depends on the age and species of the tree, the conditions in the new site location, and how careful the company is when digging out and moving the tree.
