Pineapple guava (Feijoa) care

Light

Most houseplants will scorch where pineapple guava thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Requires full sun — at least 6–8 hours of direct sunlight daily. Best flowering and fruit production comes in maximum sun; tolerates very light afternoon shade in hotter climates but yields diminish. South or west-facing aspects are ideal in UK gardens. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

For pineapple guava in the ground or in a bed, aim for weekly during growing season; reduce in winter. Soak the root zone rather than misting the foliage; deep, less-frequent watering trains roots downward and produces a more drought-resilient plant by mid-season. Keep soil consistently moist but never waterlogged. Deep weekly watering during flowering through fruit set is critical for fruit quality. Once established (2–3 years), tolerates moderate drought, but irrigation during dry spells improves yield significantly. Avoid soggy winter soil.

Soil and pot

Pineapple guava grows best in well-drained loam or sandy loam. Prefers light, moderately fertile, well-drained soil with pH 5.5–7.0. Tolerates chalk and sandy soils; will grow in clay if drainage is excellent. Does not tolerate waterlogged or constantly wet conditions. Incorporate organic matter at planting. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Pineapple guava sits happiest at around Low to moderate (30–60% RH) humidity and -9°C to 35°C (15°F to 95°F). Adapted to a wide humidity range; performs well in Mediterranean-type climates with dry summers and mild, wet winters. High humidity combined with poor air circulation can encourage fungal issues, so plant in an open, sheltered position with good airflow. If you keep the room above year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed pineapple guava sparingly. Apply a balanced fertilizer (e.g., 8-8-8 NPK) every 6–8 weeks during the growing season in spring and summer. Use approximately half the recommended dose for tree/shrub size. Trace elements (iron, magnesium, zinc) benefit fruit production. Avoid heavy nitrogen feeds, which promote foliage at the expense of fruit. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on pineapple guava in the Growli community. Each is annotated with the most common cause so you know where to start.

• Poor fruit set — Most cultivars are self-fertile but cropping improves dramatically with two different cultivars nearby for cross-pollination. Hand-pollinate flowers if bees are scarce. Also ensure full-sun siting and adequate water during fruit development.
• Frost damage to flowers — Late spring frosts can destroy flower buds and developing fruitlets even when the plant itself is unharmed. Grow in a sheltered, south-facing spot or against a wall in marginal UK zones (H3). Fleece-protect during unexpected cold snaps in flower.
• Root rot in wet soil — Feijoa will not tolerate waterlogged or poorly drained ground. Yellowing leaves and dieback in wet winters signals root rot. Plant on a slight slope, raise beds, or add grit to improve drainage before planting.

Propagation

Semi-ripe cuttings taken in summer (June–August), treated with IBA rooting hormone at 3,000 ppm and placed under bottom heat, root in 6–10 weeks. Seed germinates readily at 13–16°C but seedlings are not true-to-type — named cultivars must be propagated vegetatively. Layer low branches in autumn as an alternative. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Pineapple guava is pet-safe. Feijoa (Acca sellowiana) is not listed on the ASPCA toxic plant database for dogs or cats. The ripe fruit flesh is considered non-toxic; however, seeds and leaves contain cyanogenic compounds that may cause mild gastrointestinal upset if consumed in quantity. Keep fruit seeds away from pets as a precaution. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
