    Growing Feijoa sellowiana (Pineapple Guava)

    1. Planting

    When to Plant:

  • Best planted in spring or early fall to allow roots to establish before extreme temperatures.

    Location:

  • Choose a sunny spot for optimal flowering and fruit production. It tolerates partial shade but may yield less fruit.

    Soil Preparation:

  • Ensure soil is well-draining.
  • Amend heavy clay soil with compost or sand.
  • Maintain a pH of 5.5 to 7.0.

    Spacing:

  • Plant 10–15 feet apart for individual trees or 3–5 feet apart for a hedge.

    2. Watering

  • Water deeply and consistently during the first year to establish roots.
  • Once established, water every 1–2 weeks during dry periods, especially during flowering and fruiting.
    3. Fertilizing
  • Use a balanced fertilizer (10-10-10) in spring and midsummer.
  • Avoid over-fertilizing, which can lead to excessive foliage growth at the expense of fruit.
    4. Pruning
  • Lightly prune in late winter or early spring to remove dead or crossing branches.
  • For hedges, prune after flowering to maintain shape.
    5. Pollination
  • Although self-fertile, cross-pollination between two different varieties improves fruit set.
  • Bees and birds (especially hummingbirds) are excellent pollinators.
    6. Frost Protection
  • Hardy to about 15°F (-9°C).
  • In colder regions, provide frost protection with mulch and frost blankets.
