Apepu
What's special about Apepu
Paraguayan sour orange; used locally for juice and preserves.
Growing this variety
Apepu follows the same growing basics as Sour Orange. Variety-specific maturity above; everything else below applies to the whole Sour Orange family.
Germination
Spacing & depth
How to plant
Best grown from a grafted nursery tree for true-to-type fruit and faster harvest. From seed: use fresh seed, plant 1/2 in deep in a well-drained mix, keep 75–85°F and moist. Transplant to a sunny, well-drained site sheltered from cold winds, or grow in a large container (15+ gal) that can be moved indoors below 30°F.
Grower's tip
Sour oranges are grown for marmalade, essential oils, and rootstock — the flesh is too tart to eat fresh. Bergamot gives Earl Grey tea its aroma; Chinotto is used in Italian bitters and sodas.
Woody plant facts
Soil preferences
Deep, rich, well-drained soil with high organic matter.
6.0–6.8 for most; strawberries and blueberries prefer 4.5–6.0.
Compost annually; mulch with wood chips for perennial fruits.
Watering
1–2 in per week; deeper as plants establish.
Soak the root zone, not the foliage. Drip irrigation is ideal for long-lived plantings.
Overwatered: fruit split, root rot, mushy fallen fruit. Underwatered: shriveled berries, dropped flowers, sunscald.
Prefers top-watering — Trees are always top-watered — deep slow soak at the drip line, never at the trunk. Bottom-watering only makes sense for nursery seedlings.
Temperature tolerance
70–85°F (21–29°C)
55–70°F (13–21°C)
Tropical fruits (passionfruit, pepino, naranjilla) frost-tender. Temperate fruits (pomegranate, fig, sea buckthorn) tolerate hard freezes once established.
Container growing
Possible with the right cultivar
10+ gal (38 L) for tree fruit; 3–5 gal for berry canes; 12 in deep for strawberries
Choose dwarf or patio cultivars for containers; overwinter tender types indoors.
Detailed harvesting
Pick fully ripe — fruit sweetens on the plant, not the counter. Test with a gentle tug; ripe fruit releases easily.
Post-harvest storage & preservation
Refrigerate soft fruit unwashed 3–7 days. Freeze on trays, then bag. Dehydrate slices at 135°F. Jam or preserve surplus.
Culinary, medicinal & other uses
Fresh eating, jam, wine, syrup, drying. Use imperfect fruit for cooking; keep the best for the table.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Most perennial fruit are insect-pollinated and often not true-to-type from seed.
Named cultivars must be propagated by cutting, division, or graft to stay true.
Rinse seeds from ripe pulp; dry 1–2 weeks. Many need cold stratification before sowing.

For fleshy fruits (tomato-family, melons, ground cherries), ferment the seed out. For dry-seeded fruits (roselle, hibiscus family), just let capsules dry on the plant.
- 1Fleshy fruit: scoop seeds and pulp into a jar of water; ferment 2–4 days until it molds; rinse, dry.
- 2Dry-seeded fruit: let capsules turn brown on the plant, then split and tap seeds out.
- 3Perennial fruits (fig, pomegranate, sea buckthorn): far easier from cuttings, division, or suckers than seed.
- 4Store all seed cool, dark, and dry in labeled envelopes.
Storage: 3–6 years dry.
