They should not get alarmed if it seems like their Sasanqua or Japonica camellias are taking a long time to grow. The soil pH should be between 6.5 and 7 for the camellias to take up all the best nutrients out of the soil needed for a healthy camellia plant. You can fertilise you Sasanqua Camellia with well rotted manures, compost or you can buy the special acid loving plant food made especially for camellias and azaleas. However this fertiliser can be bought from your local supermarket or nursery in Australia and best used only after the camellia shrub has flowered. When the Sasanqua does mature, it is important to keep it well maintained. In other words by pruning your camellia, you will want to remove all the dead wood. This is done with sharp secateurs and a pruning saw this will produce new growth later on and make the plant look a picture of health. This can be done after the Sasanqua has bloomed and has just become dormant, this will also increase the number of flowers in the following year. It is also important for growers to have a general idea as to what they want when they initially begin pruning. This way they have a plan and can eliminate mistakes and prevent disappointment. It also helps with the plants overall aesthetic.

Propagating Camellias Through Cuttings

Unlike seed growing, to grow your own plants from cuttings is very rewarding and propagating camellias is no different. It is done by using semi ripe cuttings, hormone powder and soil for propagating. When propagating camellias this can be done in mid to late summer, the cuttings need to be around 4 or 5 inches long however to strike your cuttings. You need to make your cutting cut below a leaf node then take all the leaves off the cutting stem except one or two on the top where these leaves can be cut off by half, dip your cutting into hormone powder. Plant your cutting into moist propagating mix of equal parts of peat moss, sharp sand and perlite using gentle bottom heat in a propagator where you can plant and put several cuttings into one pot.

Botrytis is found on the camellias plant in late summer, as cool moist calm days favour the conditions of this plant pathogenic fungus, commonly called Botrytis blight or grey mould. By keeping a good air flow between camellia shrubs by trimming the bushes will help the air circulation and botrytis is unlikely to occur nevertheless if you need to control botrytis fungicides such as mancozeb or triforine will do this.

Leaf Gall is found more so on camellia sasanqua than the camellia japonica varieties.

You can prevent and treat this, by destroying the young galls before the spores are freed or the disease will be a lot worse the following year.
