Yah that's really close to the house. Could cause foundation issues as the tree gets older. Planting close to the home is good for cold protection, but staying a few feet away from the foundation / walls will also protect your home.
Hey Jeff,
I had tried to grow mango many years before and they all died after the winter. Most were graft type from FL and some were seedling by me. Don't know if the weather back then was colder or I was doing something wrong, but now I don't have this problem any more.
So I tried everything to get some good mangoes to eat, including planting them very close to the house -- 8" or less. Part of the reasons is they are along the driveway and not much space in between. Those trees in the pic are around 7 years old and the trunk are 4" or less. Mango has vertical deep roots as compare to avocado and white sapote which have more horizontal and destructive roots for the house. I don't think these trunk will touch the wall in my lifetime, and there is no moisture under the house foundation to attract the roots. Enjoy the good fruits first and deal with the tree size late as I'm lucky the only one in the whole neighborhood to have some mangoes to enjoy every year.
