Strawberry Guava (Cattley guava) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Fruits best in full sun, 6+ hours daily, but tolerates light partial shade better than common guava. Indoors, give it a bright, sunny window; too little light produces sparse fruit and open, weak growth. If your only bright window faces south, that's perfect for strawberry guava — same window any aroid would fry on.

Watering

Watering strawberry guava: every 5-10 days, keeping soil evenly moist while fruiting; tolerates short dry spells once established. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Prefers consistent moisture for good fruit but is moderately drought-hardy. Mulch to even out soil moisture and avoid both drought stress and standing water, which causes root problems.

Soil and pot

Strawberry Guava grows best in well-drained loam to sandy loam. Adaptable to a range of soils including sandy and rocky ground; favours fertile, well-drained loam with pH around 5.5-7.0. Excellent drainage is the key requirement in pots and in the ground. 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

Strawberry Guava sits happiest at around 50-80% humidity and 18-30°C (64-86°F). Enjoys warm, humid conditions but copes with average household humidity. As with other guavas, the practical concern is fungal disease in still, damp air, so maintain ventilation. If you keep the room above 18 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 strawberry guava sparingly. Feed every 4-8 weeks in spring and summer with a balanced or fruiting fertiliser; container plants benefit from a slow-release feed plus occasional liquid feeding. Avoid heavy late-season nitrogen, which pushes frost-tender growth. 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 strawberry guava in the Growli community. Each is annotated with the most common cause so you know where to start.

• Invasive spreading — One of the world's most aggressive invasive plants in Hawaii and other tropics; seeds spread by birds and it suckers densely. Deadhead, remove suckers and never plant near wildlands.
• Fruit flies — A major host for tephritid fruit flies, which infest ripening berries; bag fruit, pick up drops and use traps to break the cycle.
• Chlorosis in alkaline soil — Yellowing leaves with green veins signal iron deficiency on high-pH soils; correct with chelated iron and acidifying mulch.
• Scale and sooty mould — Scale insects excrete honeydew that blackens leaves with sooty mould; treat with horticultural oil and encourage predators.

Propagation

Grows readily from fresh seed (often true-ish to type for fruit colour) and also from semi-hardwood cuttings or air layering for named selections. Self-sown seedlings appear freely, so manage volunteers where invasiveness is a concern. 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

Strawberry Guava is mildly toxic to pets. Psidium cattleyanum is not individually listed by the ASPCA. As with common guava, the ripe fruit is edible to people and not documented as poisonous, but because the species is unlisted we do not assert pet-safe; seeds present a choking/blockage risk. Verify with a vet before feeding pets. 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.
