It depends.  House plants are generally not required to be inspected prior to moving to Alabama, provided none of those plants are on the noxious weed list.  Outdoor plants you are relocating to Alabama, will need a certificate of inspection indicating that they are apparently disease and pest free.  In addition, no soil may be included with the plant. No citrus trees, regardless of whether they are indoor or outdoor, may be brought into Alabama.  Even with a certificate, homeowner’s citrus trees are prohibited from being imported into Alabama.
