There are really only a few things that you want in an Orange - big size, sweet juice, and very few seeds. The Robertson Sweet Orange Tree (Citrus x sinensisn 'Robertson') checks all of those items off of the list and so much more! The glossy broadleaf evergreen foliage and divinely fragrant white blossoms are certainly a bonus!
This best-selling Sweet Orange is easy to grow! Robertson performs better than most Citrus Trees in cooler summer areas. People who grow Robertson Sweet Oranges at home will tell you how satisfying it is to go out and pick a fresh juicy orange straight from your own tree! These juicy gems ripen in late autumn to winter, so there’s less wait!
Robertson Sweet Orange is naturally dwarf but grows into a bushy shrub-like tree in no time. The fruit is very prolific and you will be up to your ears in Sweet Oranges once the tree matures! The heaviest crop will be in the winter months, but it produces fruit that hangs on the tree for a long time.
Planting and Application:
Robertson Sweet Orange is shrubby enough to be used as a hedge for privacy! Plant a hedgerow or shelterbelt with another small Orange for wildlife, screening and seclusion, plus lots of fruit! Everyone does better with a buddy, so choose a pollination partner that ripens later than Robertson to extend your harvest.
Use this shrubby plant in groupings and as backdrops and as a year-round fruiting and flowering workhorse in warm growing zones that have frost-free winters. Otherwise, ‘limb up’ into a tree form and keep Robertson as a specimen and lovely fruiting/flowering evergreen accent that you and your pollinators will enjoy!
If you don't live in a Citrus-friendly locale you don't need to worry, though, as this sweet orange will do just fine in a pot in front of a sunny window. Any growing zone can keep these as tropical poolside exotics and patio tropicals! Northern growers can just bring them indoors or into a greenhouse for the winter.

#ProPlantTips for Care:
Orange Trees fruit and flower best in full sun! Provide an open area with good air circulation, in an enriched, slightly acidic environment. Citrus do best with low moisture, allowing them to dry out a bit between waterings; container trees especially!
Although Citrus can grow year-round in warmer regions (zones 9 and 10), they can also thrive in colder areas (zones 4 to 7) as long as the tree is brought indoors before the first frost of winter.
In zone 8, you can cover your tree in the event of a cold snap or unexpected overnight freeze. Citrus will need to be planted in a sheltered spot to avoid the worst of the chill, and not planted in a low area that collects cold air. If a spot like that is unavailable, or you are in a chill-prone climate, then you are safer planting Citrus Trees in a large, deep container with wheels to easily move them to a protected location or indoors when needed.
In cold growing zones, begin slowly acclimating your tree indoors in the fall, or into a protected location, eventually moving your tree inside. Indoor plants need a bright indirect sun window, greenhouse, sunroom, or enclosed patio for the winter. In spring, reverse this process and begin acclimating your tree to again be back out in the full sun all summer. This reduces stress and leaf drop.
