I have a question: I just bought a Valencia Orange tree from a local nursery and have my gardener planted it already. It is about 6 ft to my house in the sideyard. However, the label tag says it is a standard size tree and the tree size is 15-25 ft. Spacing is 15-20 ft. The tree is still small. So it is OK for now. However, my question is whether 6 ft is far enough to my house consider when the tree becomes mature? if not, what should I do? I am concerned that if we don't leave enough space to the house, when it has grown up, the tree root would hurt my house foundation.
