Sweetie
Citrus paradisi × Citrus grandis
treeSweetie is a hybrid citrus fruit that combines the characteristics of grapefruit and pomelo, producing large, sweet fruits with pink flesh and a thin skin. The tree is vigorous and semi-dwarf in stature, typically growing 15-25 feet tall. It's prized for producing sweeter, less acidic fruit than traditional grapefruits with a pleasantly mild flavor.

Establishment (Year 1)
12 monthsYoung grafted tree with developing canopy and root system; may have some flowering but fruit is typically removed
Water regularly and deeply; stake if needed; remove early flower buds to redirect energy to growth; apply mulch 4-6 inches from trunk
Juvenile Growth (Years 2-3)
24 monthsTree develops strong branch structure; gradually increases in size and leaf canopy
Continue regular watering; begin light pruning to shape canopy; apply balanced citrus fertilizer 3-4 times per year; thin fruit if excessive flowering occurs
Flowering (Spring)
4-6 weeksFragrant white flowers bloom on mature wood; abundant flower clusters appear in early spring
Maintain consistent watering during bloom; reduce nitrogen fertilizer to encourage fruit set; protect from late frosts if in zone 9; thin flowers if desired for larger fruit size
Fruit Development (Summer-Early Fall)
12-16 weeksYoung fruitlets develop from fertilized flowers; fruits grow progressively larger through summer months
Maintain adequate irrigation, especially during hot months; thin fruit to one fruit every 6 inches of branch for larger, sweeter fruit; monitor for pests and diseases; apply citrus fertilizer monthly
Maturation & Harvest (Fall-Winter)
8-12 weeksFruits reach full size and develop deep pink flesh; skin color transitions from green to pale yellow; fruit becomes sweet and juicy
Reduce watering slightly in late fall; do not harvest until fully mature (at least 6 months on tree); fruits can stay on tree for 2-3 months after full maturity; pick by gently twisting or cutting stem

Uses
Fresh eating and juice
CulinarySweetie fruits are eaten fresh by cutting in half and scooping out flesh with a spoon, or juiced for beverages. The mild, sweet flavor and lower acidity make it more palatable than grapefruit for many people, particularly for those sensitive to citrus tartness. [source]
Salads and desserts
CulinaryThe segments can be added to fruit salads, breakfast dishes, or used as a garnish for cocktails and desserts. The attractive pink flesh adds visual appeal and subtle sweet-citrus flavor to culinary presentations. [source]
Ornamental and landscape value
HouseholdSweetie trees provide year-round aesthetic appeal with glossy green foliage, fragrant spring blossoms, and attractive golden fruit hanging on branches. The semi-dwarf form makes it suitable for larger home gardens and containers. [source]
Vitamin C and antioxidant source
MedicinalLike all citrus fruits, Sweetie is rich in vitamin C, which supports immune function, and contains flavonoids and carotenoids with antioxidant properties. Regular consumption of fresh Sweetie juice or fruit segments contributes to overall nutritional wellness. [source]
Peel and byproduct uses
HouseholdThe thick, fragrant peel can be used to make marmalade, candied peel, or infusions. The essential oils in the peel have antimicrobial and aromatic properties useful in household cleaners or aromatherapy. [source]

Harvest Tips
Sweeties mature 6-7 months after flowering, typically from October to February in most growing regions. Harvest when fruit reaches full size and skin transitions from green to pale yellow-gold; the fruit will not sweeten further after picking, so wait until mature. Gently twist and pull, or cut the stem with pruning shears. Fruit can remain on the tree for 2-3 months after ripeness without quality loss. A mature tree (4+ years old) produces 100-200 fruits per season.
Fun Facts
- 🌱 Sweetie was developed in Israel in the 1970s as a cross between Citrus maxima (pomelo) and Citrus paradisi (grapefruit), combining the best characteristics of both—the larger size and sweetness of pomelo with the more manageable size and acidity balance of grapefruit.
- 🌱 The fruit is sometimes called 'Oroblanco' in some markets, though Sweetie is technically a distinct variety with slightly different parentage and characteristics than Oroblanco, though they are very similar hybrids.
- 🌱 Unlike traditional grapefruits, Sweeties are essentially seedless and do not interact negatively with most medications that have grapefruit warnings, making them a safer citrus choice for people taking certain prescription drugs.
