[Improper Culture]

Improper Culture: Browning on upper surfaces of leaves or definitely dead brown areas on any part of leaf surfaces discloses sunburn and the plant should be given more protection.

General yellowing of the foliage discloses insufficient fertiliser, insufficient water or poor drainage.

Yellowing of foliage with veins remaining green discloses alkaline poisoning. Under no circumstances should a spray material containing D.D.T. be used on camellias as it is very harmful to some varieties, causing dropping of foliage, dying back of leaf buds and in some cases death of the plant.

In spraying, be sure that all parts of the plant are covered, especially the underneath portion of the foliage.
