Camellia planting zones

Which camellia for your zone

NC State Extension’s plant toolbox rates both Japanese camellia and sasanqua camellia for zones 7a to 9b, and Clemson says tea camellia grows throughout South Carolina, zones 7 to 9. That makes camellias a Southern and mid-Atlantic shrub; none of the sources we read rates one for zone 6 or colder.

The late-freeze table above matters most for Japanese camellias, which are in flower when the last spring freeze comes. Sasanquas and tea camellias have finished before it. NC State adds that excess sun, cold or shade can all reduce flowering.

Soil, pH and site

• Slightly acid soil, pH 5.5 to 6.5, high in organic matter and well drained (NC State). NC State says camellias are intolerant of alkaline soils, and yellow leaves may mean too little acidity. Clemson says camellias prefer a slightly acid soil.
• Shade to part shade, sheltered from drying winter winds (NC State). Clemson says they bloom best sheltered from full sun and wind, and that older plants can take full sun once their own leaves shade their roots.
• Plant shallowly. Clemson says camellias are shallow-rooted and must be planted shallowly, in a large hole that cuts back competing tree roots; NC State digs three to four times wider than the root ball but no deeper.
• Mulch 2 to 3 inches deep to hold soil moisture (Clemson). Competition for water is the one critical thing in establishment, Clemson says.
• Feed lightly. Clemson uses light applications of an azalea and camellia fertilizer in spring, following the label, and says burned leaf edges and heavy leaf drop usually mean too much fertilizer.

Test the soil before planting so you know the pH; your county extension office can arrange it.

When to plant

Clemson says camellias can be planted any time of year if they are planted properly, mulched and watered often, and gives October to November and March to mid-April as the best times. They are slow to grow and slow to establish (NC State, Clemson), so the first two summers are the ones to water through.

Pruning

Camellias need very little pruning, Clemson says: remove damaged branches and long shoots that spoil the shape. NC State limits it to dead or damaged wood, unproductive branches and overlong shoots, and says to prune immediately after flowering or in early summer, because next year’s flowers form on old growth and later pruning may sacrifice them.

For a hard cut, Clemson says cutting back severely, with no leaves left, can be done safely from Valentine’s Day to about May 1, and that dead and weak stems can come out any time.

Bud drop

Some flower bud dropping is natural, because many camellias set more buds than they can open (Clemson, NC State). Clemson says bud drop can also be caused by too little water in summer, and NC State says drought in August and September can reduce flowering the next spring, and that over- or under-watering can cause buds to drop.

Common problems

• Dieback and canker: Clemson names it one of three serious diseases in South Carolina. UF/IFAS says new spring growth wilts and twigs turn brown; prune 6 inches below the affected part and disinfect the tools.
• Root rot: Clemson and UF/IFAS say it follows planting too deep, poor drainage and too much water; the leaves turn light green, then yellow, and drop.
• Camellia flower blight: brown spots that spread through the flower, affecting flowers only and worst on Japanese camellias (UF/IFAS). NC State says remove infected plant parts promptly.
• Tea scale and other scales on the undersides of leaves: Clemson calls tea scale the serious insect pest, and UF/IFAS says it is the most common of more than 30 scales on camellias.
• Algal leaf spot, aphids and spider mites (UF/IFAS); magnesium and nitrogen deficiency, the most common nutritional problems on camellias in Florida (UF/IFAS).

Where a spray is needed, UF/IFAS names insecticidal soaps and horticultural oils for scales, aphids and mites. Follow the label and your state’s rules.

Common mistakes

• Planting too deep. Clemson says camellias are shallow-rooted and must be planted shallowly.
• Alkaline soil. NC State says camellias are intolerant of it.
• Pruning late in the year, which NC State says may sacrifice next year’s flowers.
• Letting the soil dry out in late summer, which NC State says can reduce next spring’s flowers.
• Overfeeding. Clemson says burned leaf edges and leaf drop usually mean too much fertilizer.
• Full sun and wind on a young plant (Clemson).

Camellias are a Southern shrub in our sources, rated to zones 7a–9b. We found no Texas A&M or LSU AgCenter source on camellias we could read, and none of our sources covers growing them in zone 6 or colder.

Questions

What zones do camellias grow in?

NC State Extension rates Japanese and sasanqua camellias for zones 7a to 9b, and Clemson says tea camellia grows throughout South Carolina, zones 7 to 9.

What soil pH do camellias need?

Slightly acid. NC State Extension gives pH 5.5 to 6.5 in well-drained soil high in organic matter, and says camellias are intolerant of alkaline soils.

When should I prune a camellia?

Right after it flowers or in early summer, NC State Extension says, because next year’s flowers form on old growth. Clemson says a severe cutback can be done from Valentine’s Day to about May 1.

Why are my camellia buds falling off?

Some bud drop is natural, because many camellias set more buds than they can open. Clemson says too little water in summer can cause it, and NC State says over- or under-watering can too.

What is the difference between a sasanqua and a Japanese camellia?

Sasanquas flower in fall and winter, grow faster and have smaller leaves; Japanese camellias flower from late winter into spring with larger flowers (NC State, Clemson).
