Everything it needs
9 essentials at a glance
Watering
Lychee trees prefer consistently moist soil but should not be waterlogged.
Water deeply once a week during the growing season, reducing frequency in winter. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause leaf drop and wilting.
Light
Lychee trees thrive in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in a south-facing garden or patio. They can tolerate partial shade but may produce fewer fruits.
Soil
Lychee prefers well-draining, sandy loam with a pH range of 5.5 to 7.0.
Ensure good drainage to prevent root rot; a mix of potting soil, sand, and perlite is recommended for container growth.
Humidity
These trees thrive in high humidity levels of 60-80%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of low humidity include brown leaf tips and leaf drop.
Temperature
Lychee trees prefer temperatures between 70°F to 90°F (21°C to 32°C) and are hardy in USDA zones 10-11.
They can tolerate short periods of cold down to 30°F (-1°C) but should be protected from frost.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 6-8 weeks.
Signs of nutrient deficiency include yellowing leaves and poor fruit development.
Pruning
Prune Lychee trees in late winter to shape them and remove dead or crossing branches.
Use sharp, clean pruning shears. Deadheading is not necessary, but thinning can improve air circulation.
Repotting
Repot Lychee every 2-3 years or when roots outgrow the pot.
Choose a pot 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of drainage holes and stunted growth. Carefully remove the plant, trim any damaged roots, and place it in fresh soil.
Propagation
Lychee can be propagated through seeds or grafting.
For seeds, soak them overnight, plant in a well-draining mix, and keep moist until germination. Grafting is best done in spring when the tree is actively growing.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture and reduce watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Leaf drop
Why it happens
Can result from sudden temperature changes or insufficient watering.
How to fix it
Maintain consistent watering and protect the tree from cold drafts or sudden temperature fluctuations.
Fruit drop
Why it happens
May occur due to stress from drought or nutrient imbalance.
How to fix it
Ensure consistent watering and apply a balanced fertilizer to support fruit development.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Allow the soil to dry out between waterings and improve drainage by using a well-draining potting mix.
Pest infestations (e.g., aphids, scale)
Why it happens
Pests can thrive in high humidity and poor air circulation.
How to fix it
Inspect regularly and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, fertilize your Lychee tree with a balanced fertilizer and ensure consistent watering as new growth begins. Monitor for pests as the weather warms.
Summer
During summer, maintain regular watering and provide shade during extreme heat. This is also the time when fruit begins to develop, so ensure proper nutrients.
Fall
In fall, reduce watering as temperatures cool and prepare the tree for winter. Prune any dead or crossing branches to maintain shape.
Winter
In winter, protect your Lychee tree from frost and cold drafts. Water sparingly, allowing the soil to dry out between waterings.
Toxicity & Safety
Lychee is non-toxic to pets and children. However, unripe fruit can cause hypoglycemia in humans if consumed in large quantities.
