All You Need to Know About Chilean Guava (Ugni molinae) and Its Strawberry-Flavored Berries

July 27, 2026

Chilean guava, also known as ugni or murtilla, adds a delightful touch to gardens with its aromatic small berries and bushy growth habit. Native to South American forests, this evergreen shrub is appreciated for its relative hardiness and a flavor reminiscent of wild strawberries. It is suitable for both orchard enthusiasts and city dwellers looking to experiment with container gardening. Keywords like Chilean guava, Ugni molinae, and murtilla frequently surface in searches for an original and easy-to-manage fruiting shrub.

What is Chilean Guava?

Chilean guava is a shrub belonging to the Myrtaceae family, characterized by its glossy, oval, evergreen leaves. In spring, it produces delicate, pinkish-white bell-shaped flowers that attract bees and other pollinators. The fruits are small, aromatic, red berries that become translucent when ripe. The fine seeds have a historical use as a coffee substitute.

This species can withstand frost down to -8°C or even -10°C in well-drained and dry soil. Its compact form makes it an excellent choice for low hedges, flower beds, or pot cultivation on patios. Gardeners appreciate both its ornamental value and fruit production, with historical references linking ugni's popularity to Victorian Europe.

Slightly fragrant, the berries evoke the taste of wild strawberries and are rich in vitamin C. They can be enjoyed fresh, transformed into sorbets or jams, and are also used in traditional macerations like murtado in Chile. Its wind and salt spray resistance make this shrub suitable for coastal gardens in regions with mild winters.

Where to Plant and What Soil is Best for Chilean Guava?

Chilean guava thrives in sunny to partially shaded locations with fresh, acidic, and very well-drained soil. Excess moisture can lead to root issues, while light soil helps prevent water stagnation. Coastal areas with mild winters are particularly favorable for this shrub.

For pot cultivation, a draining potting mix is essential, and it’s advisable to avoid saucers that can hold standing water to reduce humidity. Gardeners in northern climates can protect pots from frost to safeguard the above-ground parts. When planting in hedges or as standalone specimens, allow for approximately 1.5 to 1.8 meters of space in all directions.

When to Sow, Take Cuttings, and Plant?

Successful sowing typically occurs in spring or autumn, avoiding periods of frost. A light substrate and moderate temperatures encourage germination. While patience may be required, the seeds generally sprout without much difficulty.

Semi-augmented cuttings placed in a humid environment can yield good results in summer. The use of rooting hormones can aid in recovery, and regular watering during the initial weeks is crucial. Repotting a young guava plant is best done in spring.

In-ground planting should be scheduled after the last frosts in spring or in autumn if the climate remains mild. Space plants about 1.5 meters apart to allow for healthy growth. A sheltered location from cold winds and mulching at the base will enhance the chances of successful establishment.

How to Maintain and Prune for Optimal Results

The critical period for care occurs during the first summers after planting, as the shrub requires regular watering to establish itself. Once rooted, ugni is more drought-resistant but still prefers a moist environment. Moderate watering remains important for potted plants to prevent root desiccation.

Training pruning occurs at the end of winter, around February-March, to remove dead or poorly oriented branches. For hedgerow management, a more severe cut can be tolerated without compromising fruiting. Maintenance helps limit overcrowding and improves airflow, thereby reducing health risks.

• Practical tips: organic mulching at the base, regular watering during the first year, avoid excessive moisture at the collar.
• For container cultivation: repot in spring, use a draining substrate, and provide winter protection if frost is frequent.

When and How to Harvest the Berries?

Fruits typically ripen between August and October, depending on the climate and variety. Ripe berries can be identified when their red color lightens and the flesh becomes fragrant. Harvesting is done by hand, picking each berry individually to avoid damaging the delicate branches.

Berries can be consumed raw in fruit salads or processed into sorbets, jams, or liqueurs. The traditional maceration in spirits and sugar creates murtado, a popular treat in Chile. Short-term refrigeration preserves the aromas, while freezing allows for longer storage.

What Are the Pests and How to Prevent Them?

Chilean guava is generally resistant to serious diseases, but thrips are the most common nuisance. Regular monitoring of young shoots helps detect early infestations. Stagnant moisture can also lead to issues, highlighting the importance of good drainage.

Eliminating saucers that collect water under pots and using a layer of clay pebbles at the bottom can mitigate risks associated with excess moisture. Moderate mulching prevents thermal shock to the roots without fostering excessive humidity. Crop rotation and aeration of planting beds complete preventive practices.

Which Varieties to Choose and Culinary Uses?

The most commonly recommended variety for fruit production is ‘Elite,’ known for its high yield. The Ugni genus includes about ten species, but Ugni molinae remains the most accessible. The choice of variety will depend on whether the focus is ornamental or fruit-bearing.

In culinary applications, the berries lend themselves well to fresh and preserved preparations. Small quantities can easily be turned into delicate jams or flavorful sorbets. Roasted seeds are sometimes used as a hot beverage substitute in certain traditions.
