Psidium guajava
Guava, common guava, guayaba: native to tropical America, it is now cultivated in all the warm regions of the world. Its pinkish flesh releases an exceptionally intense fragrance — a single ripe fruit can scent an entire room. Good news for our climates: it fruits very well in a pot, from just two years of age.
Characteristics:
-
Highly aromatic fruits: thick yellowish skin and pinkish flesh with a powerful fragrance.
-
Evergreen foliage: dark green oval leaves with prominent yellow veins and a whitish, downy underside.
-
Early fruiting: from two years of age in a pot, with fruits the same size as those grown in the ground.
-
Long production period: a well-maintained plant can produce for up to forty years.
Precautions:
- It tolerates temperatures only down to -2 °C: in our climates, it must be grown in a pot to overwinter in a conservatory or greenhouse. Only Corsica and sheltered areas of the far south offer the possibility of trying it in the ground.
- In temperate regions, flowering and fruiting remain unpredictable: a harvest is never guaranteed, even with proper care. It is also a beautiful evergreen houseplant.
Sowing advice:
-
Exposure: very bright and warm, in full sun behind glass or outdoors in summer.
-
Soil: rich, light, and well drained. In a pot, mix rich potting soil with sand and compost, and add a good layer of clay pebbles at the bottom: drainage is crucial.
-
Method: no cold stratification — this tropical species requires warmth instead. Soak the seeds for 24 to 48 hours in lukewarm water to soften their hard seed coats, then sow them 1 cm deep in a substrate kept moist at 25-30 °C. Germination is slow and irregular: allow 3 to 8 weeks. See how to sow your seeds.
Planting advice:
- Transplant into a terracotta pot at least 30 cm wide, which regulates moisture better than plastic. Repot every two or three years.
- It grows very well as a low bush rather than a tree: this is even recommended to make harvesting easier and keep it contained in a pot.
Care advice:
- Water regularly during the growing season, reducing watering significantly in winter. Mist the foliage in dry conditions.
- Overwinter in the light, never below 5 °C. Prune after fruiting to maintain a compact shape.
Harvesting advice:
- Pick the fruits when the skin changes from green to yellow and they yield slightly under your finger. The fragrance then becomes very noticeable from a distance: this is the best indicator of ripeness.
Benefits for biodiversity:
- Its white flowers, with numerous stamens, are very rich in pollen and attract bees and bumblebees during their summer activity.
- Grown in a pot without any treatment, it fits perfectly into a permaculture-managed terrace.
Uses:
- Fresh fruit, juice, sorbet, jam, or fruit paste — its fragrance holds up very well during processing. Also a beautiful ornamental evergreen plant.
Harvesting your own seeds:
Scoop the pulp from a fully ripe fruit, let it ferment for two to three days in a little water, then rinse it thoroughly: the many small, hard seeds will separate from the flesh. Dry them before storage. See how to store your seeds.
