How to Grow Republic of Texas Orange Trees


For a tree that doesn't require a lot of attention, the Republic of Texas orange tree sure delivers some great tasting oranges. The Republic of Texas orange tree has been around a while, growing in the Santa Fe area of Texas since the mid-1800s. It is a thorny, cold-tolerant citrus tree that will bloom in the spring and produce medium-size oranges in December. The Republic of Texas orange tree will grow 15 feet in height and width and is hardy to USDA zones 8 through 11.

Step 1

Plant the Republic of Texas orange tree where it will get at least six hours of sun per day and in a somewhat sheltered area out of the way of strong winds and gusts.

Step 2

Water the Republic of Texas orange tree slowly but thoroughly every two weeks, keeping the soil around the tree moist to within 1 inch of the surface. Skip the watering for two weeks if it rains.
