Acerola
Malpighia Emarginata
Acerola, commonly known as Barbados Cherry, is a tropical fruit-bearing shrub native to the Caribbean and Central America. Renowned for its high vitamin C content, it is cherished for both its ornamental beauty and delicious, tart cherries. Growing Acerola is rewarding, as it not only enhances gardens but also provides nutritious fruits.
Everything it needs
9 essentials at a glance
Watering
Acerola prefers consistently moist soil, requiring watering every 2-3 days during the growing season and once a week in the winter.
Ensure the top inch of soil dries out between waterings to prevent root rot. Signs of over-watering include yellowing leaves and a mushy stem, while under-watering may cause leaf drop and wilting.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in a south-facing window or outdoors in a sunny garden. It can tolerate partial shade but may produce fewer fruits in lower light conditions.
Soil
Acerola prefers well-draining soil with a pH range of 6.0 to 7.0.
A mix of potting soil, sand, and perlite is recommended for optimal drainage. Ensure the pot has drainage holes to prevent water accumulation.
Humidity
Acerola enjoys moderate to high humidity levels, ideally between 50-70%.
To increase humidity, mist the leaves regularly or place a humidity tray nearby. Signs of humidity stress include browning leaf tips and leaf drop.
Temperature
The ideal temperature range for Acerola is 70-85°F (21-29°C).
It is hardy in zones 10-12 and can tolerate brief periods of cooler temperatures down to 30°F (-1°C). Protect from frost during winter months.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10, applying every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor fruit production.
Pruning
Prune Acerola in late winter or early spring to shape the plant and remove any dead or damaged branches.
Use sharp, clean pruning shears for a clean cut. Deadheading spent flowers can encourage more blooms and fruit.
Repotting
Repot Acerola every 1-2 years or when roots start to emerge from the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include stunted growth and roots visible at the surface. When repotting, gently loosen the roots and place in fresh potting mix.
Propagation
Acerola can be propagated through seeds or stem cuttings.
For seeds, soak them in water for 24 hours before planting in a moist potting mix. For stem cuttings, take 4-6 inch cuttings from healthy plants, dip in rooting hormone, and plant in a well-draining mix. Best timing for propagation is in spring.
When it's unhappy
Yellow leaves
Why it happens
Usually caused by over-watering or nutrient deficiency.
How to fix it

Leaf drop
Why it happens
Can occur due to sudden temperature changes or under-watering.
How to fix it
Maintain stable temperatures and ensure consistent moisture in the soil.
Fruit drop
Why it happens
Often a result of stress from inadequate light or fluctuating moisture levels.
How to fix it
Ensure the plant receives enough sunlight and maintain even watering.
Browning leaf tips
Why it happens
Typically indicates low humidity or over-fertilization.
How to fix it
Increase humidity levels and reduce fertilizer application.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Allow soil to dry out and improve drainage; consider repotting if severe.
Care through the year
Spring
In spring, increase watering as temperatures rise and begin fertilizing every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives full sun and maintain consistent moisture. Watch for pests and diseases.
Fall
In fall, reduce watering frequency as temperatures cool and prepare the plant for winter by cutting back on fertilization.
Winter
In winter, protect the plant from frost and reduce watering to once a week, allowing the soil to dry out slightly.
