Expert tips
The key tip
Camellia reticulata is somewhat less hardy than C. williamsii; give it an acidic, cool soil and light shade.
The common mistake
Exposing it too much to direct sun or planting in chalky soil: the leaves gradually yellow, flowering becomes poor and the plant ages badly.
The pro's trick
In February, before flowering, remove a few old leaves at the base of the flowering branches: this aerates the shrub and reduces flower rot.
Care
Regular and measured watering
Keep the soil moist but never waterlogged, especially during growth and flowering. Water deeply once or twice a week depending on climate. Prefer soft or rainwater, as limestone can yellow the leaves. Reduce slightly in winter.
Partial shade or filtered light
The reticulata camellia prefers partial shade, sheltered from direct afternoon sun. A very bright location but without direct rays promotes beautiful flowering. Protect it from cold, dry winds that damage flower buds.
Light pruning and maintenance
Prune after flowering (May-June) to remove dead or crossing branches and open up the shape. Avoid severe pruning, as camellias don't tolerate major wounds well. Pinch young shoots to encourage branching.
Moderate nutrient supply
Apply fertilizer for acid-soil plants in spring and summer at low doses. Enrich the soil with compost or acid amendment each autumn. Avoid excess nitrogen, which reduces flowering.
Acidic and well-structured soil
Plant in acidic substrate (pH 5.5 to 6.5) made up of heather soil, compost and potting mix. Ensure excellent drainage to prevent root rot. Mulch generously with bark or leaves to maintain moisture and coolness.
Prevention of common problems
Watch for mealybugs and red spider mites during dry periods. Root rot can occur if drainage is poor. Bud drop: check watering, air humidity and avoid moving the plant during bud formation.
Did you know?
The reticulata camellia has been highly prized by Asian collectors for centuries: in China, some old varieties have been passed down through generations and can live over 500 years. Its giant, richly colored flowers inspired many poems and paintings during the Ming dynasty, where the plant symbolized excellence and longevity.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
