Sea Foam Camellia

Sea Foam Camellia is hardy outdoors in USDA zones 7 to 10 and grows best in full to part sun with afternoon shade in hot climates. Like all camellias, it is acid-loving and wants rich, moist, well-drained soil that stays cool at the roots.

Planting

1. Choose a spot with morning sun and afternoon shade, sheltered from harsh wind and early-morning winter sun on the buds.
2. Provide acidic (roughly pH 5.5 to 6.5), well-drained soil rich in organic matter; amend heavy or alkaline soil with compost and peat or pine bark fines.
3. Dig the hole twice as wide as the root ball but no deeper than it is tall.
4. Set the plant so the root flare sits slightly above soil level, planting a touch high to avoid settling too deep, then backfill and water in thoroughly to remove air pockets.
5. Mulch 2 to 3 inches deep with pine bark or pine straw to keep roots cool and moist, keeping the mulch pulled back a few inches from the trunk.

Care & maintenance

• Water. Keep the soil consistently moist, especially the first two years and while buds are forming; never let it dry out completely, but avoid soggy ground.
• Feed. Apply an acid-forming fertilizer formulated for camellias, azaleas, and rhododendrons (a holly-tone type) right after flowering, with a lighter follow-up feeding in early summer; do not feed in late summer or fall.
• Light. Best in part sun with afternoon shade; too much hot, direct sun scorches leaves, while deep shade reduces bloom.
• Prune. Camellias bloom on old wood, so prune right after the flowers finish in spring, before new buds set. Thin and shape lightly; heavy late pruning removes next year's blooms.
• Mulch & winter care. Maintain a cool, mulched root zone year-round. In the colder end of its range, shelter from drying winter wind and morning sun to protect open buds from frost damage.
• Pests & disease. Watch for tea scale on leaf undersides, aphids, and spider mites; good airflow and proper soil pH help prevent yellowing (chlorosis) and petal blight. Remove fallen, spent blooms to limit blight.

When does the Sea Foam Camellia bloom, and for how long?

It flowers from winter into spring, a stretch when most shrubs are dormant. Because the buds open in sequence rather than all at once, a single plant can show fresh white blooms over several weeks of the cool season.

Why isn't my camellia blooming?

The most common causes are pruning at the wrong time (camellias set buds on old wood, so late pruning cuts off next year's flowers), too much shade, over-feeding with high-nitrogen fertilizer, or buds that were nipped by hard frost or dried out from inconsistent watering during bud set. Correct the timing and site and bloom usually returns.

When and how should I prune it?

Prune right after flowering finishes in spring, before the plant sets next season's buds. Thin out crowded or crossing stems and lightly shape; avoid hard summer or fall pruning, which removes the wood that carries the coming year's blooms.

Does it grow in sun or shade?

Both, in balance. It performs best in full to part sun with shade during the hottest part of the day. Morning sun with afternoon shade gives the richest foliage and the most flowers, while deep shade reduces blooming and full afternoon sun in hot climates can scorch the leaves.

How do I keep the leaves deep green instead of yellow?

Yellowing usually signals soil that is too alkaline or roots that are too wet or too dry. Keep the soil acidic (about pH 5.5 to 6.5), feed with an acid fertilizer made for camellias and azaleas, mulch to hold even moisture, and make sure the site drains well.

Can I grow it as a hedge or in a container?

Yes. Its upright 10-to-12-foot habit and evergreen foliage make it well suited to an informal screen or hedge, and it can also be grown in a large pot with acidic, well-drained potting mix in zones 7 to 10, given consistent water and winter wind protection.
