Passion Fruit Quick Growing Tips

  • Passion fruit needs frost-free winters and an average temperature of 68 to 75°F (20-24°C) during the growing season.
  • Passion fruit grows well in the corner of a sunny patio or against a south-facing wall, if not grown indoors.
  • Start passion fruit seeds indoors and set young plants outdoors in late spring at the same time you plant out melons.
  • Train passion fruit vines up wires or a trellis.
  • Water passion fruit vines plentifully and feed them with a tomato fertilizer (high in nitrogen).
  • In winter cut back last year’s sideshoots to within two buds of the main stems; they won’t fruit again; cutting back sideshoots encourages the growth of new sideshoots that will bear fruit,

Best Climate and Site to Grow Passion Fruit

  • Passion fruit is a tropical and subtropical plant. It is native to South America. Passion fruit vine grows best in frost-free regions.
  • There are a few cultivars that can survive temperatures in the upper 20sF. Vines may lose some of their leaves in cool winters; the roots will resprout even if the foliage is killed.
  • Plant passion fruit in full sun except in areas where summers are very hot; in very hot regions plant passion fruit in partial shade.
  • Passion fruit is a vining plant that grows rapidly; plant passion fruit where it can climb a trellis or wire fence. Passion fruits have tendrils and are natural climbers.
  • Passion fruit grows best in well-drained, compost-rich, sandy loam with a soil pH of 5.5 to 6.5.
  • Avoid planting passion fruit where the soil is constantly wet. Also, avoid planting passion fruit in spots where it can be damaged by wind.
  • Avoid planting passion fruit in low spots where cold air or frost can settle.
  • If you grow passion fruit indoors, place it in a bright south-facing window.

Choosing the Right Passion Fruit Plant

  • Yellow passion fruit is sweet, acidic, and tropical with mild floral notes.
  • Purple passion fruit has a flavor and aroma richer than yellow passion fruit. It is also less acidic.
  • The flavor of both is reminiscent of guava.

Spacing Passion Fruit

  • Passion fruits are vigorous growers. One vining plant can grow 30 to 40 feet. Train vines up a trellis or support to avoid stems of separate plants tangling. Training vines on a trellis will make fruit harvest easier.

How to Plant Passion Fruit

  • Plant passion fruit where it cannot be damaged by frost or cold winter temperatures.
  • Plant passion fruit in well-drained soil. A soil pH of 5.5 to 6.5 is optimal.
  • Prepare a planting hole half again as deep as the root ball and twice as wide.
  • Add a mixture of 2 cups of kelp and 1 cup of bone meal to the hole prior to planting.
  • Set the plant in the hole and refill the hole around the root ball with a combination of native soil and aged compost or commercial organic planting mix. Firm in the soil so that no air pockets.
  • Form a small basin of soil around the plant to hold irrigation water.
  • Mulch around the base of passion fruit to conserve soil moisture, especially in dry, hot regions.

Container Growing Passion Fruit

  • Passion fruit can be grown in containers, but the vigorous vines will need the support of a trellis.
  • Choose a container 24 inches wide and deep or larger.

Feeding Passion Fruit

  • Passion fruit plants are heavy feeders; use a 10-5-20 fertilizer. Use a high potassium fertilizer to encourage fruiting. Too much nitrogen will result in leafy growth and less fruit set.

Watering Passion Fruit

  • Keep the soil evenly moist for quick, even growth. Keep the soil moist but not wet. Plant in moisture-retentive, well-drained soil.
  • Consistent soil moisture is important for best fruit production; if the soil dries, the fruit will shrivel and drop.
  • Overwatering can cause root rot.
  • Passion fruit vines grown indoors should be placed in a saucer with pebbles; fill the saucer with water to keep the air humid.

Training and Pruning Passion Fruit

  • Train passion fruit to a trellis or overhead support such as a T-post to keep separate vines from tangling and to make the harvest of fruit easier. Passion fruit has tendrils and is a natural climber.
  • Prune to eliminate dead and dying and weak and unproductive growth. Prune to keep the plants within bounds. Thin passion vine to encourage air circulation.
  • Prune after harvest; cut back vigorous growth by one-third.
  • Avoid removing foliage that shields fruit from hot summer sunburn.

Passion Fruit Pollination

  • Purple passion fruit plants are self-pollinating.
  • Yellow passion fruit plants are not self-pollinating. They depend on insects to transfer pollen from one plant to the next for pollination.
  • The carpenter bee is the most effective passion fruit pollinator. The pollen is heavy and sticky making pollination by honeybees difficult.

  • Fresh passion fruit pulp can be used as a dessert topping on cakes or ice cream.
  • Passion fruit can be juiced or made into jam or jelly or into ice pops.

Passion Fruit Propagation

  • Passion fruit is usually grown from seed. Seed removed from the fruit can be planted right away. Germination will occur in 10 to 20 days. Sow seed ½ to 1 inch deep.
  • Passion fruit can be propagated by layering or by stem cuttings and also by grafting. Yellow passion fruit rootstock is used for grafting.
  • To propagate passion fruit by stem cuttings, choose a healthy stem and cut it about 6 inches down with 3 to 4 leaf nodes; remove the bottom leaves then dip the cutting in a rooting hormone and plant it in potting mix. Rooting should occur in about 90 days.

Passion Fruit Problems and Control

  • Passion fruit is susceptible to attack by insect pests and diseases.
  • Fusarium fungal disease can cause foliage to wilt and dieback; remove infected foliage; space plants well apart to encourage air circulation. Plant disease-resistant varieties.
  • Woodiness virus causes discoloration and crinkling of leaves, fruit is small and deformed. Aphids commonly spread this disease.
  • Yellowing leaves can be caused by a lack of magnesium or nitrogen.
  • Root-knot nematodes can attack roots; there is no cure for infected plants; solarize the soil when possible.
