Loquat
Eriobotrya Japonica
Eriobotrya japonica, commonly known as loquat, is a fruit-bearing tree native to southeastern China. Its sweet, tangy fruits and attractive foliage make it a popular choice for gardens, providing both beauty and delicious harvests.
Everything it needs
9 essentials at a glance
Watering
Eriobotrya japonica prefers well-drained soil and should be watered deeply but infrequently.
Water every 1-2 weeks during the growing season, allowing the top 2-3 inches of soil to dry out between waterings. In winter, reduce watering to once every 3-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Loquat thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
For optimal growth, place it in a location that receives morning sun and afternoon shade, especially in hotter climates. It can tolerate some shade but may produce fewer fruits.
Soil
The ideal soil for Eriobotrya japonica is well-draining, sandy loam with a pH range of 6.0 to 7.5.
Ensure good drainage to prevent root rot, and consider using a potting mix designed for fruit trees or a blend of peat, perlite, and compost.
Humidity
Loquat prefers moderate humidity levels around 40-60%.
To increase humidity, mist the leaves or place a humidity tray filled with water and pebbles nearby. Signs of humidity stress include browning leaf tips and leaf drop.
Temperature
Eriobotrya japonica thrives in temperatures between 60-75°F (15-24°C).
It is hardy in zones 8-10 and can tolerate brief periods of cold down to 20°F (-6°C). Protect the plant from extreme heat and frost during the winter months.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 14-14-14.
Fertilize every 6-8 weeks during the growing season, and reduce feeding in the fall and winter. Signs of nutrient deficiency include yellowing leaves (nitrogen), poor fruit development (phosphorus), and stunted growth (potassium).
Pruning
Prune Eriobotrya japonica in late winter or early spring before new growth begins.
Use sharp, clean pruning shears to remove dead or diseased branches and to shape the tree. Deadheading is not necessary, but thinning out crowded branches can improve air circulation and fruit production.
Repotting
Repot Eriobotrya japonica every 2-3 years or when the roots outgrow the pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter and refresh the soil. Carefully remove the plant from its pot, loosen the roots, and place it in the new pot with fresh soil.
Propagation
Loquat can be propagated through seeds or cuttings.
For seeds, collect ripe fruit, remove the seeds, and plant them in a well-draining potting mix. Keep the soil moist until germination, which takes 2-4 weeks. For cuttings, take 6-inch stem cuttings in late spring, dip them in rooting hormone, and plant them in a pot with a mix of peat and perlite. Keep the cuttings in a warm, humid environment until roots develop.
When it's unhappy
Leaf drop
Why it happens
Usually caused by sudden changes in temperature or humidity.
How to fix it
Maintain consistent environmental conditions and avoid placing the plant in drafty areas.
Yellowing leaves
Why it happens
Often a sign of over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and adjust watering practices, and consider fertilizing if nutrient deficiency is suspected.
Fruit drop
Why it happens
Can occur due to stress from drought or poor pollination.
How to fix it
Ensure consistent watering and consider hand-pollinating if necessary.
Pest infestations (e.g., aphids, spider mites)
Why it happens
Common in stressed plants or those in low humidity.
How to fix it
Inspect regularly and treat with insecticidal soap or neem oil as needed.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Ensure proper drainage and allow the soil to dry out between waterings.
Care through the year
Spring
In spring, fertilize your loquat tree and ensure it receives adequate water as new growth begins. Prune any dead or diseased branches.
Summer
During summer, monitor soil moisture closely and provide additional water during dry spells. Protect the tree from extreme heat.
Fall
In fall, reduce watering as the tree enters dormancy. Continue to monitor for pests and prepare for winter by mulching around the base.
Winter
In winter, water sparingly and protect the tree from frost. If in a pot, consider moving it indoors or to a sheltered location during cold spells.
Toxicity & Safety
Eriobotrya japonica is generally considered non-toxic to pets and children. However, the seeds contain cyanogenic compounds and should not be ingested in large quantities, as they can cause nausea and other symptoms.
Good to know
Why are my loquat leaves turning yellow?
Yellowing leaves on your loquat may indicate over-watering or a nutrient deficiency. Check the soil moisture and consider fertilizing if needed.
How often should I water my loquat tree?
Water your loquat tree every 1-2 weeks during the growing season, allowing the top 2-3 inches of soil to dry out between waterings.
What type of soil is best for Eriobotrya japonica?
Loquat prefers well-draining sandy loam with a pH of 6.0 to 7.5. Ensure good drainage to prevent root rot.
How do I propagate loquat?
You can propagate loquat through seeds or stem cuttings. For seeds, plant them in well-draining soil and keep moist until germination.
When is the best time to prune my loquat tree?
Prune your loquat tree in late winter or early spring before new growth begins to maintain its shape and remove any dead branches.
Is loquat toxic to pets?
Eriobotrya japonica is generally non-toxic to pets, but the seeds should not be ingested in large quantities due to potential cyanogenic compounds.
What are common pests that affect loquat trees?
Common pests include aphids and spider mites. Regularly inspect your plant and treat with insecticidal soap or neem oil if necessary.
