About & Species

Common Guava
(Psidium guajava)

The Common Guava is a small evergreen shrub or small tree native to the Caribbean and South/Central America. The Common Guava, also called Yellow Guava and Lemon Guava, grows 30 to 40 feet tall. It is widely grown in tropical and sub-tropical regions around the world. The Common Guava grows slow for the first few months and then grows fast. Trees grown from seed can produce fruit in 2 to 8 years.  

Soil Type: Adaptable to a wide range of soils, heavy clay and light sandy soils. The best quality guava fruits are grown in river basins.

Zones: 9 to 11

Germination Range: 60-80%

Stratification Requirement: none required

Indoor Planting: If your seeds require stratification or scarification – do the recommended pretreatment before planting indoors. Planting Instructions: Fill a container with seed starting mix to about ½ inch from the top. Place your seeds 1 inch to 1 ½ inches below the soil surface. Gently water your seeds to keep moist, not soaking wet. Heat & humidity is critical for germination. Germination may occur in 1 week or as long as 3 months (depending on the species). Place the seed container on a heat mat under growing light(s). Keep your growing lights on 14 hours per day. Keep your heat mat on 24 hours per day. Once your seeds germinate, move each seed into its own container under the growing lights and on the heat mat. Keep your seedlings indoors for 2-3 months before transplanting outdoors in the spring (May to June).

Outdoor Planting: If your seeds do not require stratification: the best time to plant tree and shrub seeds outdoors is after the last frost in your area (spring). In the Northern states – the best time to plant seeds outdoors is from May to June. If your seeds require pretreatment: you should plant your seeds outdoors before the ground freezes in your area (late September to early November). Your seeds will naturally stratify during the cold winter. Germination usually occurs in May or during the spring season.
