Care at a glance

Light

Lychee needs sun on the leaves, not just bright ambient room light. Full sun, at least 6-8 hours daily, for strong growth and fruiting. Young trees benefit from light afternoon shade in the hottest climates; under glass, the brightest possible position. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water lychee keep evenly moist in growth; water when the top 3-5 cm dries. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Lychee has shallow roots and dislikes both drought and waterlogging. Mulch to hold moisture. A drier spell in late autumn/winter helps induce flowering, then resume regular watering.

Soil and pot

Lychee grows best in deep, acidic, well-drained loam. Prefers rich, slightly acidic soil around pH 5.0-6.5 with good drainage and organic matter. It is sensitive to alkaline and saline soils, which cause iron deficiency and leaf chlorosis. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Lychee sits happiest at around 50-70% humidity and 20-33°C (68-91°F). Enjoys moderate to high humidity typical of subtropical regions. Dry air can scorch leaf margins; container plants benefit from humid, sheltered spots away from drying wind. If you keep the room above 20 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed lychee sparingly. Feed lightly and regularly in the growing season with a balanced fertiliser; young trees prefer little-and-often. Avoid heavy nitrogen near flowering. Acidifying feeds and chelated iron help on near-neutral soils. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on lychee in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Leaf chlorosisYellowing between leaf veins, usually iron or micronutrient lockout on alkaline soil. Acidify the soil and apply chelated iron.
  • Failure to flowerNeeds a cool, dry winter rest to initiate flower buds; mild winters, excess nitrogen or heavy pruning suppress fruiting.
  • Fruit drop and splittingErratic watering and sudden rain after dry spells cause young fruit to abort or split. Keep soil moisture steady and mulch heavily.
  • Slow establishmentLychee is genuinely slow; seedlings may take 5-10+ years to fruit, so air-layered or grafted plants are preferred for reliable cropping.

Propagation

Almost always air-layered (marcotting) or grafted to fruit true and quickly, often within 2-4 years. Seed germinates readily but must be sown fresh, is highly variable, and fruits very slowly. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Lychee is mildly toxic to pets. Lychee is not individually listed by the ASPCA, so treat it with caution and verify with a vet. The seed and unripe arils are the concern: they contain saponins and hypoglycin-type compounds (MCPG) linked to dangerous low blood sugar, so keep seeds away from pets. Ripe flesh is generally eaten, but the pit should never be offered. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Lychee care — frequently asked questions

What is the common name for Litchi chinensis?

Litchi chinensis is most commonly called Lychee, but it is also known as Lychee, Litchi, Chinese cherry. The names refer to the same species, so care instructions for Lychee apply identically to anything sold as Litchi.

How much light does lychee need?

Lychee grows best in direct sun (at least 4-6 hours). Full sun, at least 6-8 hours daily, for strong growth and fruiting. Young trees benefit from light afternoon shade in the hottest climates; under glass, the brightest possible position.

How often should I water lychee?

Water lychee keep evenly moist in growth; water when the top 3-5 cm dries. Lychee has shallow roots and dislikes both drought and waterlogging. Mulch to hold moisture. A drier spell in late autumn/winter helps induce flowering, then resume regular watering. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is lychee toxic to cats and dogs?

Lychee is mildly toxic to pets. Lychee is not individually listed by the ASPCA, so treat it with caution and verify with a vet. The seed and unripe arils are the concern: they contain saponins and hypoglycin-type compounds (MCPG) linked to dangerous low blood sugar, so keep seeds away from pets. Ripe flesh is generally eaten, but the pit should never be offered.

What USDA hardiness zone does lychee grow in?

Lychee is rated for USDA zone 10-11 (mature trees tolerate brief light frost; protect below zone 10) and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
