Problem Solver: Camellias
Is your camellia losing leaves?
If a camellia has a good position in the garden with well drained soil and layer of cow manure as mulch they should grow pretty well.
However if the plants roots are very dry or you add fertilizer onto dry roots this can cause camellias to loose leaves.
10 litres of water per week at this time of the year is adequate and the leaves should re grow quite soon.
