Puna (Ehretia acuminata)

Also known as: Koda tree, Smooth-leaved Ehreti, Pihata

A widely found tree in eastern Asia and Australia is the Melaleuca, also known as paperbark. This tree typically thrives in wetlands and can grow from a small seed to a height of 30 meters. Due to its relatively soft and workable wood, it is frequently used in furniture making.

How to Water Puna?

For Ehretia acuminata, each watering session should thoroughly wet the soil throughout the root zone, aiming for about 500 milliliters per session. The soil should feel moist but not waterlogged, mimicking the plant's natural environment requiring visible moisture retention without pooling water on the surface.

What Is the Ideal Temperature Range for Puna?

Ideal Temperature: 66 ~ 77℉

Ehretia acuminata thrives best within a consistent temperature range of 66°F to 77°F. This range allows the plant to perform essential physiological processes efficiently, promoting robust growth and development. Maintaining this temperature range can help ensure healthy foliage and flowering, as fluctuations outside these conditions may stress the plant.

What Soil is Best for Puna?

Soil type: Loam, Sandy loam

Soil PH: 6.5 ~ 7.5

Ehretia acuminata thrives in nutrient-rich soil, which provides essential minerals for its growth. This richness ensures the plant has a strong structure and supports its vibrant foliage and blossoming flowers. Well-draining soil is crucial for preventing root rot in Ehretia acuminata. It allows water to flow through easily, ensuring roots receive adequate moisture without becoming waterlogged. Soil that retains moderate moisture supports Ehretia acuminata by providing a steady supply of water between watering sessions, essential for consistent growth and health.

How to Fertilize Puna?

Fertilizer type: Balanced

For Ehretia acuminata, the optimal fertilizer amount should be balanced to promote growth without overwhelming the roots. When using liquid fertilizers, a diluted solution (approximately 1/2 strength of the recommended dosage on the label) should be applied bi-weekly during the growing season to stimulate healthy leaf and root development.

How to Prune Puna?

Pruning Time: Spring, Summer

Avoid pruning during the late autumn and winter months as the plant is dormant and may not heal properly. Ideal times are early spring and throughout summer, when the plant is actively growing. While pruning is beneficial, over-pruning can stress the plant. Limit the cutting back of branches to no more than one-third of the total foliage to keep the plant healthy. After pruning, monitor the plant for signs of pests or disease as open cuts can be susceptible. Taking timely action can help in maintaining plant health. More About Pruning Techniques→

How to Propagate Puna plant?

Propagate Time: Spring, Early spring, Late spring

Collect ripe seeds from the plant, clean them, and dry them before planting. Soak them overnight in water to enhance germination success.

Choose a healthy branch from the mother plant and cut a 4-6 inch section. Remove the leaves at the bottom and dip the cut end in rooting hormone.

Select a low growing branch and bend it until it touches the ground, burying a portion of it in soil to encourage root growth while still attached to the parent plant.

How to Repot Puna plant?

Repotting frequency: Every 2-3 years

Ehretia acuminata requires repotting when you notice the roots curling in the pot or growing through the drainage holes. Another sign is when the growth slows significantly, indicating it's pot-bound. Spring and Summer are the ideal seasons to undertake this task, as the plant enters an active growth phase, minimizing stress and promoting robust recovery.

Select a pot that is 1-2 inches larger in diameter than the current one. Ensure it has adequate drainage holes to prevent waterlogging, which can lead to root rot. A slightly bigger pot encourages healthier root expansion, facilitating nutrient uptake and overall growth.

Use well-draining fertile loam, which holds enough moisture for the roots without becoming waterlogged. This type of soil provides the essential nutrients Ehretia acuminata thrives on, ensuring rich leaf production and vigorous growth.
