About Lychee

Litchi chinensis · also called Lychee, Litchi · tropical

Lychee is a slow-growing subtropical evergreen tree grown for its fragrant, translucent fruit. It demands a frost-free site, acidic well-drained soil, and a brief cool, dry spell to trigger flowering. Patient growers in warm climates or large containers are rewarded, but seedlings can take many years to fruit.

Mature size: 10-12 m in the ground over decades; readily kept to 2-3 m in a large container or by pruning.

How to tell lychee needs repotting

Repotting on a calendar is less reliable than reading the plant. For lychee, watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and lychee wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot lychee

Every 2–3 years; top-dress in the in-between years. Lychee's growth habit — rounded, densely canopied evergreen tree with glossy compound leaves and a slow, steady growth rate. — sets the pace.

What size pot to step lychee up to

Move up exactly one pot size. A heavy lychee dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot lychee

Early spring, just as new growth restarts, is the ideal window for lychee. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting lychee

Consider top-dressing first. If lychee is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh deep, acidic, well-drained loam beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave lychee in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave lychee in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for lychee

Lychee wants 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. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting lychee — frequently asked questions

How often should you repot lychee?

Every 2–3 years; top-dress in the in-between years for lychee. Fully repot lychee only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with deep, acidic, well-drained loam. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does lychee need?

When is the best time of year to repot lychee?

Should you top-dress or fully repot lychee?

For a big, heavy lychee, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise lychee after repotting?

Not immediately. Wait about 4 weeks after repotting lychee. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
