Woody plant facts

USDA zones
Hardy in zones 6–9
Mature height
Dwarf 8–10 ft · semi-dwarf 12–15 ft · standard 18–25 ft
Mature spread
8–25 ft (2.4–7.6 m), matching the rootstock you plant
Years to fruit
3–5 years on grafted stock; 6–10 years from seed
Chill hours
Varies by cultivar — check the tag against your winter chill total
Pollination
Plant a compatible pollenizer that blooms at the same time unless the tag says self-fertile.
Rootstock
Grown on a rootstock chosen for size and soil. Seedlings do not come true to the parent fruit.
Planting depth for seed
Sow pips and stones 1/2–1 in (12–25 mm) deep after stratification.
Soil pH
6.0–7.0
Disease & problem notes
Open-centre pruning, fallen-fruit cleanup and dormant sprays handle most brown rot and scab pressure.

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 — Top-water at the base — canes are prone to cane blight and anthracnose when leaves stay wet.

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.

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 chinese sweet tea 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.
