Camellia reticulata · also called net-vein camellia, yunnan camellia · flowering

Camellia reticulata, the net-vein camellia from Yunnan, China, produces the largest flowers of any camellia — single to semi-double blooms up to 20 cm across in shades of deep pink to rose-red, appearing late winter to early spring. It is a more open, less tidy shrub than C. japonica, requiring milder climates or frost protection; spectacular in sheltered coastal gardens.

Mature size: 3–6 m (10–20 ft) tall, 2–4 m (6.5–13 ft) wide at maturity in favourable climates; typically kept smaller in UK gardens

Watch for — Bud drop: Buds set in summer but fail to open, dropping prematurely. Causes include irregular watering during August–October, sudden root disturbance, or being moved as a container plant during bud set. Keep moisture consistent and site plants permanently.

How to tell net-vein camellia needs repotting

Repotting on a calendar is less reliable than reading the plant. For net-vein camellia, 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 net-vein camellia 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 net-vein camellia

Every 2–3 years; top-dress in the in-between years. net-vein camellia's growth habit — open, loose-branched, upright evergreen shrub or small tree. less compact and more angular than c. japonica; large, distinctly net-veined (reticulate) dark green leaves. slower-growing than c. japonica in cool climates. — sets the pace. Camellia reticulata, the net-vein camellia from Yunnan, China, produces the largest flowers of any camellia — single to semi-double blooms up to 20 cm across in shades of deep pink to rose-red, appearing late winter to early spring.

What size pot to step net-vein camellia up to

Move up exactly one pot size. A heavy net-vein camellia 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 net-vein camellia

Early spring, just as new growth restarts, is the ideal window for net-vein camellia. 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 net-vein camellia

Consider top-dressing first. If net-vein camellia 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 acidic, humus-rich, well-drained ericaceous loam or compost 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 net-vein camellia in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave net-vein camellia 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 net-vein camellia

net-vein camellia wants acidic, humus-rich, well-drained ericaceous loam or compost. pH must be 4.5–6.0. In-ground planting: deeply incorporate ericaceous compost, pine bark, and leaf mould. Mulch 8–10 cm deep with bark chips annually to retain moisture and maintain acidity. In containers, use ericaceous potting compost and pot on every 2–3 years. Intolerant of alkaline or waterlogged conditions. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting net-vein camellia — frequently asked questions

How often should you repot net-vein camellia?

Every 2–3 years; top-dress in the in-between years for net-vein camellia. Fully repot net-vein camellia 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 acidic, humus-rich, well-drained ericaceous loam or compost. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does net-vein camellia need?

When is the best time of year to repot net-vein camellia?

Should you top-dress or fully repot net-vein camellia?

For a big, heavy net-vein camellia, 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 net-vein camellia after repotting?

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