Oroblanco Grapefruit Tree Information and Care
The Oroblanco grapefruit is a hybrid, having the parentage of an acidless pummelo and a white seeded grapefruit developed at the UC Riverside in 1958. The patent is held by the University of California, and
the variety was released in 1980. This tree doesn’t do well in the cold, but is vigorous and adapts quickly to most environments.
Water a grapefruit tree regularly for healthy growth and adjust the frequency of irrigation based on the season. Water less frequent, about once weekly in the Winter, and more frequently 2 – 3 times per week in the Summer until tree establishes.
Peel the skin of Oroblanco grapefruit like an orange, separate into segments, and enjoy for breakfast. Oroblanco grapefruit is also known as “Sweetie”. Harvest in the Fall and Winter during the months of September to December.
Prune the Oroblanco grapefruit tree to about 8 – 15 feet tall and wide, if not a grapefruit tree can grow over 20 feet tall and wide. Space can be as close as 10 feet apart, and up to 20 feet apart for pollinating.
Our Oroblanco grapefruit trees are strong, evergreen citrus. Plant under the full sun, in soil that drains well. Use high quality planting mix and organic citrus fertilizer.
