Tangelos are easy to grow in home and backyard gardens.
Tangelos are hybrids of mandarins and grapefruits. The name tangelo is short for “tang” tangerine (a popular name for mandarins) and “elo” from pummelo (once the name used for grapefruits, but in actuality a separate fruit).
Tangelo fruits can vary in color and size but are commonly about the size of an orange. They generally have loose skin and are easier to peel than oranges. They are readily distinguished from oranges by a characteristic “nipple” at the stem end.
Tangelo flavor is tart and tangy; the fruit is aromatic; they can be juicy at the expense of flesh. Tangelos are best adapted to hot climates.
Tangelo Growing Tips
- Tangelos grow best in USDA Zones 9 and 10. Choose a location that gets at least 8 hours of sun or more each day. Set tangelos in a protected spot away from a prevailing breeze or wind. Avoid planting in low spots where cold air or frost can settle.
- Plant tangelos in compost-rich, loamy soil that is well-drained. Keep the soil evenly moist. Protect plants with plant blankets if temperatures near freezing are forecast.

- Tangelo is an evergreen citrus tree. A standard tangelo can grow 20 to 30 feet tall and 15 to 25 feet wide. Trees on dwarfing or semi-dwarfing rootstock will grow to one-fourth to one-third the size of a standard, that is 5 to 7 feet tall and wide.
- Dwarf tangelos can be grown in containers. Choose a container at least 18 inches deep and wide. Move tangelos to larger containers after a year or two.
- Tangelos can be grown indoors in a very brightly lit spot. Potting soil should be coarse, acidic and well-drained. Tangelos growing in containers in cold-winter regions should be moved indoors in autumn before the first frost.
- Most tangelos are self-fertile. The popular tangelo ‘Minneola’ requires a pollinator to ensure good fruit set. Most mandarins will pollinate tangelos with the exception of Satsumas, ‘Orlando’ and ‘Seminole’. You can help a tree set fruit by taking a small brush and moving pollen from one flower to another. Honeybees and other pollinators can assist as well. Trees will begin bearing fruit at 1 to 2 years old. A mature tree will bear 40 to 50 fruits. Fruits commonly ripen from winter into spring.
- Tangelos are hardy to the mid 20sF. Protect plants from freezing temperatures to avoid dieback or death. Fruit most be protected from temperatures below freezing.
- Feed tangelo trees in mid-spring, early summer, and late summer. Use an organic fertilizer formulated for citrus trees, generally higher in nitrogen than phosphorus and potassium.
- Take care when harvesting fruit not to pull the fruit or the rind will tear around the stem; cut stems with pruning shears is the best harvest practice.
- Tangelos, like other citrus, are usually not bothered by insect pests. Watch for slugs or leafminers. Indoors watch for mites or aphids.
Tangelos can be used as a substitute for mandarin oranges or sweet oranges.
Tangelos are sometimes referred to as “Honeybells”.
