Spacing & depth

Sow depth
1" (2.5 cm)
Seed spacing
3 seeds per hill, 36–48 in (90–120 cm) apart; thin to 1–2 strongest
Mature plant spacing
36–48 in (90–120 cm)
Row spacing
72 in (180 cm)

How to plant

Sow in hills of 3 seeds, thin to strongest. Mulch heavily under vines to keep fruit off wet soil.

Grower's tip

Ripe when the tendril nearest the fruit browns and the underside turns yellow.

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 soil line with drip. Powdery mildew loves wet leaves — keep water off the vines.

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 watermelon from what you already have

Save seeds when you eat a fully ripe melon — seedless watermelons are sterile hybrids and won't work.

  1. 1Rinse the seeds off in a colander to remove pulp.
  2. 2Ferment 1–2 days in a jar of water if any pulp remains, then rinse again.
  3. 3Dry on a plate 1–2 weeks until snap-hard.
  4. 4Store dry. Sow after last frost in warm soil.

Storage: 5–6 years dry.
