Recommendations about culture
• Sun in California
– 70% shade for C. japonica
– 30% shade for C. sasanqua
• Sasanqua may tolerate from 0% shade to 80% shade
• Watering 2-3 times a week during summer
– Once a week during winter
• Temperature – not a problem in California
– Japonica is generally hardy down to 15 °F (-10 °C)
• Pruning is optional
• With proper culture, insects and diseases are rarely a
problem
– Petal blight is an exception
Fertilization for the ground
• Any form of nitrogen
– Ammonium sulphate, synthetic urea
– Blood meal, Chicken manure
– Water two days before and immediately after fertilization
• Phosphorus, Potassium, microelements are not
recommended – our California soil already has plenty
of them
• One application in March maybe enough
– Second application in July is optional
• But watch for heat waves – do not fertilize during hot weather
Fertilization for the container
• Before each burst of growth
– April 15 and 4th of July
• Liquid Camellia fertilizer at half-recommended
strength
• Water two days before fertilizing
– Plant should not be water-stressed
• Osmocote is not recommended – may quickly
release during hot weather
• Cottonseed meal (3:2:1) is a viable alternative
Recommended container soil mix
• Equal parts of peat moss, perlite and “Camellia &
Azalea mix” from the store
– Watering 2-3 times a week on summer
– once a week during winter
• Why not just a store mix?
– Too heavy = root rot
• Why not just peat moss and perlite?
– Once dry it difficult to make moist again
• Why not just a store mix and perlite?
– Not acid enough, may contribute to chrolosis
