Poncirus Trifoliata (PT) is the best rootstock for growing citrus trees along the upper Texas Gulf coast, even into Louisiana. PT is a three petal leafed citrus (see picture below) that was brought from China as a rootstock for citrus along the gulf coast. It is the only citrus that loses it leaves in the winter and goes dormant. It will not freeze. Only way south in the Texas Rio Grande Valley, Florida, and soil flooded by salt water is PT not suited for growing citrus.
When buying a citrus tree try to find out what is its rootstock. If you can not find it on the plant label, check out where the originating nursery is located. (Some local nurseries buy from wholesellers in the Texas valley) If it is located in the Texas valley, good chance it is grafted on sour orange. My trees are labeled on what rootstock they are grafted. Sour orange that is used for rootstock produces leaves with a single main petal attached at the base to a petiole (small petal) which in turn is connected to the stem.

PT’s only draw backs are:
