USDA zones
Hardiness varies by species
Sun
Full sun to part shade
Start indoors
Start indoors 6–8 weeks before last frost if needed
Direct sow outdoors
After last frost or in fall for stratified seed
Days to harvest
Varies by species

Germination

Germination time
14–60 days (species dependent)
Soil temperature
65–75°F (18–24°C)

Spacing & depth

1/8–1/4 in (3–6 mm); very small seeds surface-sown
Seed spacing
1–2 in (2–5 cm) apart in flats
Mature plant spacing
Give mature plant its full spread
Row spacing
N/A — transplant individually

How to plant

Sow in well-drained mix at the recommended depth. Keep evenly moist and provide bright light after germination. Harden off before transplanting outdoors to a suitable permanent site.

Pre-sow treatment

Cold stratification

Many woody/perennial species need 30–90 days cold moist stratification — check species-specific guidance.

Grower's tip

Opuntia humifusa — Devil's-tongue, Eastern Prickly Pear, Indian Fig.

Soil preferences

Soil type

Deep, rich, well-drained soil with high organic matter.

pH range

6.0–6.8 for most; strawberries and blueberries prefer 4.5–6.0.

Amendments

Compost annually; mulch with wood chips for perennial fruits.

Watering

Frequency

1–2 in per week; deeper as plants establish.

Method

Soak the root zone, not the foliage. Drip irrigation is ideal for long-lived plantings.

Over vs. under

Overwatered: fruit split, root rot, mushy fallen fruit. Underwatered: shriveled berries, dropped flowers, sunscald.

Top-water or bottom-water?

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

Ideal daytime air temp

70–85°F (21–29°C)

Ideal nighttime air temp

55–70°F (13–21°C)

Frost sensitivity

Tropical fruits (passionfruit, pepino, naranjilla) frost-tender. Temperate fruits (pomegranate, fig, sea buckthorn) tolerate hard freezes once established.

Container growing

Container-suitable?

Possible with the right cultivar

Recommended pot size

10+ gal (38 L) for tree fruit; 3–5 gal for berry canes; 12 in deep for strawberries

Notes

Choose dwarf or patio cultivars for containers; overwinter tender types indoors.

Succession planting

Perennials fruit on their own schedule — no succession. For annual fruiting (tomatillo, ground cherry, roselle) treat like a warm-season vegetable.

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

Pollination

Most perennial fruit are insect-pollinated and often not true-to-type from seed.

Isolation needs

Named cultivars must be propagated by cutting, division, or graft to stay true.

How to save

Rinse seeds from ripe pulp; dry 1–2 weeks. Many need cold stratification before sowing.

From your kitchen — grow devil's-tongue from what you already have

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.

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

Storage: 3–6 years dry.
