The
Growing of Camellias and Azaleas
Selecting
a position in the garden
Camellias and Azaleas are shade lovers, yet enjoy a light
location rather than a dark or heavily shaded position.Choose
a cool position, protected from the afternoon heat in
summer. An eastern, southern or south eastern aspect,
or a verandah, patio or in between buildings usually offer
the desired protection. The presence of large shrubs or
trees in the garden can offer the required protection.
Ensure there is protection from the dry hot north wind.
Filtered sunlight through 50 to 70% shade cloth is ideal.
Avoid planting close to established trees, whilst they
give excellent shade and protection, root competition
may be attracted by the improved soil and watering conditions.
An answer is to grow them above the ground in a pot. Consider
Camellia sasanqua and the sun tolerant selection
of Azaleas for the more exposed positions, discuss location
and variety choices with our helpful team. back

The
Soil
Camellias and Azaleas prefer an
acidic, (ie. no limestone) rich friable soil with a high
humus content (decomposed organic matter). A pH (the scale
used to gauge soil acidity) of 5-6 is desirable. The acidity
and structure of soil can be improved greatly by incorporating
generous quantities of soil conditioners such as YATES
peat moss, pulverised pine bark or humus (well composted
organic matter).
To improve soil acidity for existing plants apply sulphur
YATES Acetone. However if in doubt to the pH of your soil,
bring a sample to the nursery for testing and advice on
correction methods. Clay type soils are improved by the
addition of gypsum, or YATES hose on Clay Breaker and
soil conditioners, these all assist in breaking up clay
particles, better drainage and aeration will result. Sandy
soils and water retention is improved with generous quantities
of soil conditioners and humus. back

Preparing
a Garden Bed
Prepare an area at least 1 metre
square, adding to the soil the necessary conditioners.
It is advisable to raise the bed 10 to 20 cm above the
surrounding ground to ensure good drainage, soil depth
need only be 40-50 cm deep as these are shallow rooted
plants. back to top
Planting
Remove the plant from the container,
not allowing the root ball to break up in your hands.
The plant should be placed in the hole no deeper than
it was originally. Now back fill, gently firming the soil
down whilst ensuring the plant remains upright and straight.
Stake and fertilise. Finally water the plant well to settle
it in. Planting is best carried out during the months
of March through to October. back

Growing
in a Pot
Tub culture is becoming increasingly
popular and has many advantages. Where soil and climatic
conditions are unsuitable or where garden space is limited,
tub plants are ideal for furnishing a patio area or verandah.
When in flower the tub can be shifted to a feature position,
and returned to a more protected position, at the onset
of summer. When potting, use Newman's quality Acidic Camellia
and Azalea potting mix. Azaleas and Camellias can be grown
in tubs, with the correct maintenance, for many years.
If starting with a small plant, eg. 15 cm pot size, it
should be only potted into a slightly larger container,
eg. 20/25 cm pot, there it should remain for up to 2 years.The
next potting would take it to a 30 cm container where
it could remain for up to 3 years. From this stage you
can go to a much larger tub, as long as the plant is growing
vigorously. Now in a large tub, maintenance involves regular
fertilising and mulching and every 3 to 4 years repotting
back into the same tub, ask at Newmans if you are still
unsure.
Potting can be carried out during the months of March
to October, August/September being the optimum months,
just after flowering, but before
the
new growth starts.

General Care
Fertiliser
Apply fertiliser only during the
spring, summer and early autumn and never exceed the directions
on the container.Do not over fertilise!, Camellias and
Azaleas often die from too much, but rarely from not enough.
Symptoms of over feeding can be marginal leaf burn, leaf
discolouration, bud drop, leaf drop, or buds failing to
opening properly.
For potted plants we recommend Osmocote or Nutricote slow
release fertiliser. Applied in Spring it continues to
feed until Autumn, this can be followed by a light application
of YATES Blood and Bone in March/April.
For plants grown in the ground we recommend either YATES
Gro Plus Camellia and Azalea fertiliser (instructions
on the pack) or YATES Blood and Bone at the rate of a
heaped cupful to a square metre in September, December
and February.
Always water well after fertilizing. back

Watering
The frequency of watering varies
with the prevailing weather and your type of soils. One
or two deep soakings a week rather than daily light watering
is best. After watering allow the surface of the soil
(or mulch) to start to dry a little before it's next watering.
To maintain a humid atmosphere it is beneficial to spray
the foliage and its surroundings regularly during the
hottest days in summer. back
to top
Mulching
Mulching the soil surface in pots
and the ground keeps the soil cool, this conserves moisture
and suppresses weeds. Use a mulch which decomposes readily
and the soil will benefit too. Some ideal mulches are
cow manure, pulverised pine bark, YATES peat moss, mushroom
compost or pea straw. Soil wetting agents such as SaturAid
or Wettasoil applied before summer are recommended.

Pruning
Prune to increase bushiness, to
stimulate vigour or improve general shape,
this should be done during the late winter and early spring.

Insect
Pests
Camellias and Azaleas are generally
resistant to insect attacks but can occasionally be affected.
Control can be achieved by the following treatments,
Aphids and Thrips
- use Pyrethrin or Confidor, or wash a small infestation
off with a hose.
Scale - use YATES
Malascale (A mixture of Malathion and White oil) or YATES
Scale Gun.
Mites or Red Spider
- use Sulfine or Pest Oil, or if the infestation is persistent
speak to one of our team for advice.
Caterpillars - use
Dipel, or if they persist use Mavrik.
Remember always keep strictly to the manufacturers recommendations
when mixing and applying, always read safety directions
carefully.
Always consult our helpful team if in doubt as to what
is attacking your plants. back

Problems
Feel free to discuss or bring samples
to the nursery, we are only too happy to advise on any
problems you may be experiencing with your Camellias and
Azaleas.
