Fertilizers should be applied in an economic but methodical
process to ensure a steady release of nutrients over the growing
season. Applications can be applied a week or two before new
growth buds begin to swell. It may be best to apply nutrition
in small to moderate quantities of three or more periods from
March to September. Higher nitrogen rates are best applied in
spring, then changing to moderate nitrogen and phosphate, and
to higher potassium in September. When using nitrogen-containing
fertilizers, "slow release" nitrogen forms are much
more efficiently taken up by plants. Many growing camellias in
containers use one of the organic sources of nitrogen, such as
cotton seed meal, applied once a month all year long. Seed meals
release nitrogen as they decompose slowly and continually continuously
over the long stretch. Slow continuous release keeps plants well
nutrified during the entire growing season.
Early application of nutrients is essential for flower bud
development in that the petal count can be related to general
growth vigor of plants. Super buds begin formation as day length
increases during May. Plants should be in good growth form by
this time. Plants will be showing flower buds by the first part
of July.
Water is not only essential for normal growth but a continuous
supply ensures constant mineral uptake and maximum expansion
of cells making up the new growth. Irregular water supplies interrupt
the growth process which can result in stunted leaves and stems.
If flower buds are being formed during water stress, their quality
will be affected. Maximum water availability is even more important
while flowers are opening. One needs to prepare a flexible watering
program to include an irrigation system and a measuring device
such as a simple rain gauge to ensure a constant water supply.
Major pruning should best be completed over winter or by early
spring. While spring and summer growth develops, minor pruning
can be accomplished by breaking out soft new growth. The ultimate
pruning plan will reflect one's interests in camellia culture.
Thick vegetation is the rule for landscape plants. Inside branches
should be removed to reduce the accumulation of pests, scale
in particular. Growers primarily interested in producing show
flowers generally thin out more branches than those grown for
landscape use. Flower buds are thinned, leaving large plump ones
for show exhibition.
Pest control is a never-ending chore. While leaves and stems
are young and tender, scale insects, "crawler" stage,
move from last season's old leaves up to new succulent growth;
ants move aphids to the newest growing points; spider mites appear
from nowhere! Keep a constant lookout for these and other pests.
When discovered, take immediate action. Your favorite garden
center personnel or your county extension agent will be glad
to help you. Select the appropriate control,
The camellia grower's work is cut out for his or her cultivation
schedule. Good nutrition, water control, light pruning and pest
control result in beautiful blooms for the camellia flowering
season. |
