Chilean guava (Ugni molinae)

Also known as: Chilean Guava, Strawberry Myrtle

The Chilean guava, or Ugni molinae, is an evergreen shrub originating from Chile and Argentina. It features aromatic foliage and bell-shaped flowers that are typically white or pale pink. This plant thrives in temperate regions with well-drained soil and produces edible, dark crimson berries. Hardy and resilient, it often grows well when sheltered from extreme conditions, making it suitable for growth under tree canopies or in sunny, protected areas.

What Is the Ideal Temperature Range for Chilean guava?

Ideal Temperature: 60 ~ 75℉

The ideal temperature range for Ugni molinae, commonly known as Chilean Guava, is between 60°F and 75°F. This range allows the plant to thrive, promoting optimal growth, flowering, and fruit production. Maintaining the plant within this temperature range is crucial for its overall health and vitality, ensuring that it can develop its characteristic berries that are both flavorful and aromatic.

What Soil is Best for Chilean guava?

Soil type: Loam, Sandy loam, Acidic soil

Soil PH: 5.5 ~ 7

Ugni molinae prefers soil that retains moisture well without becoming waterlogged. This helps support consistent hydration, essential for berry production, and prevents root desiccation during dry periods. Rich, well-aerated soil provides abundant nutrients for growth. A balanced supply of essential minerals promotes vibrant foliage and optimal berry yield, enhancing overall plant health. Well-drained soil prevents excess water accumulation and root rot. This ensures the roots are well-oxygenated, promoting healthy plant development and avoiding common water-related stress.

How to Fertilize Chilean guava?

Fertilizer type: Balanced

When fertilizing Ugni molinae, use a balanced liquid fertilizer. Apply 1 tablespoon per gallon of water, ensuring the soil remains moist but not saturated. Proper measurement helps avoid any potential root burn while ensuring optimal nutrient delivery.

How to Prune Chilean guava?

Pruning Time: Spring, Summer

Begin by examining the plant for any dead, diseased, or damaged branches. These can usually be identified by their brown or brittle appearance. Carefully snip these away to improve the overall health of the plant. To shape Ugni molinae, focus on maintaining an open center. This helps in maximizing sunlight exposure to all parts of the plant. Trim back any branches that cross over or tangle up with others. After shaping, look for any weak or thin branches and cut them back to a bud facing outward. This encourages the plant to focus its energy on producing new, robust growth from stronger parts. More About Pruning Techniques→

How to Propagate Chilean guava plant?

Propagate Time: Late spring,Early summer

Select a healthy branch from the parent plant. Use pruning shears to take a 4-6 inch cutting, ensuring it includes a few leaves. Remove any lower leaves to expose the node.

Dip the cut end of the cutting into rooting hormone. This step is optional but can increase the chances of successful root development.

Insert the hormone-treated cutting into a pot filled with well-draining potting soil. Water lightly and cover with a plastic bag to create a humid environment.

How to Repot Chilean guava plant?

Repotting frequency: Every 2-3 years

Ugni molinae suggests that it's time for a new home when roots begin to circle the pot or sprout from the drainage holes. If you notice that the soil dries out rapidly after watering or if the plant's growth appears stunted, these are strong indicators that repotting is needed to refresh the soil and give it room to grow.

Select a pot that's about 1-2 inches larger in diameter than the current one. A pot that's too large may lead to water retention, risking root rot. Make sure it has drainage holes to allow excess water to escape, keeping the plant's roots healthy and well-aerated.

Ugni molinae thrives in acidic conditions, so choose a well-draining mix that's rich in organic matter, like a blend of peat and sand. Such a mix retains necessary moisture but prevents waterlogging, supplying the plant with essential nutrients while allowing its roots to breathe.
