Xmas Hampers...There will be a separate raffle for a large number of Xmas Hampers at the December meeting. This raffle will be a free one to members with each membership receiving one free ticket.
This is always good festive season fun and a great way to enjoy our Xmas meeting.
There will be the usual plant raffle for which there will be the normal charge.

*******************************

Meeting Start time

Please take note!!
The meetings of the Wanneroo/Joondalup Orchid Society now take place at St Luke's School at Woodvale, Whitfords Ave and Duffy Terrace, with the entrance to the parking area being on Duffy Tce
Also.... The meeting will start at 7.30

Please make sure that your orchids arrive by 7.15 so that they can be entered, placed on the trestles so the meeting can start without all the talking at the back of the hall and the judges can get on with their work.
Please be considerate of others.

******************************

And so…….. Another orchid year comes to a close, where we and our orchids have managed to survive yet another trip around the Sun.
Xmas is coming and the geese are running for cover. (Not to
mention turkeys, porkers, the odd chook) Yes, situation normal!!
So let us try to not overdo things this festive season with excessive imbibing or just plain pigging out, as we should all be planning to have ourselves good and healthy (along with our long suffering orchids,) to be bright eyed and bushy tailed and ready for the wonderful world of orchid challenges that we are bound to face in 2019.
Yes!!! The Wanneroo/Joondalup Orchid Society is in need of your living, breathing presence in the new year as we have had too many orchid friends depart this orchid world in recent years.
So do take care of yourself and your orchids during the crazy
season and try to remain in the land of the living so that we can all return to orchid normalcy in the New Year.

Do have the happiest of Xmas's and the best of the best New Year for 2019.

Your Committee wish you all the very best for Xmas and the New Year

Fertiliser - By Trevor Burnett
The great bulk of plants are composed of carbon, hydrogen and oxygen. The carbon is derived from the air in the form of carbon dioxide.
The hydrogen contained in organic material of the plant is derived from the water taken up by the roots, while oxygen is obtained from both water and the atmospheric sources, including carbon dioxide and oxygen.
Plants cannot live and grow on water and air alone. They need a variety of inorganic minerals and other constituents that are supplied to the plant from the soil and other media.


The roles of these nutrients are summarised below:
Major Elements (Macronutrients)
Nitrogen (N) is a major component of proteins, hormones, chlorophyll, vitamins and enzymes essential for plant life. Nitrogen metabolism is a major factor in stem and leaf growth (vegetative growth). Too much can delay flowering and fruiting, while deficiencies can reduce yields, cause yellowing of the leaves and stunt growth.
Phosphorus (P) is necessary for seed germination, photosynthesis, protein formation and almost all aspects of growth and metabolism in plants. It is essential for flower formation. Low pH (<4) results in phosphate being chemically locked up in organic soils. Deficiency symptoms are purple stems and leaves; maturity and growth are retarded. Yields of flowers are poor. Premature drop of flowers may often occur. Phosphorus must be applied close to the plant's roots for the plant to be able utilise it. Large applications of phosphorus without adequate levels of zinc can lead to a zinc deficiency.
Potassium (K) is necessary for formation of sugars, starches, carbohydrates, protein synthesis and cell division in roots and other parts of the plant. It helps to adjust water balance, improves stem rigidity.
Sulfur (S) is a structural component of amino acids, proteins, vitamins and enzymes and is essential to produce chlorophyll.
Deficiencies show as light green leaves. Sulfur is readily lost by leaching from soils and should be applied with a nutrient formula. Some water supplies may contain sulfur.
Magnesium (Mg) is a critical structural component of the chlorophyll molecule and is necessary for functioning of plant enzymes to produce carbohydrates, sugars and fats. Deficient plants appear chlorotic, show yellowing between veins of older leaves; leaves may droop. Magnesium is leached by watering and must be supplied when feeding. It can be applied as a foliar spray to correct deficiencies.
Calcium (Ca) activates enzymes, is a structural component of cell walls, influences water movement in cells and is necessary for cell growth and division. Some plants must have calcium to take up nitrogen and other minerals. Calcium is easily leached. Calcium, once deposited in plant tissue, is immobile (non-translocatable) so there must be a constant supply for growth. Deficiency causes stunting of new growth in stems, flowers and roots. Symptoms range from distorted new growth to black spots on leaves.
Micronutrients
Iron (Fe) is necessary for many enzyme functions and as a catalyst for the synthesis of chlorophyll. It is essential for the young growing parts of plants. Deficiencies are pale leaf color of young leaves followed by yellowing of leaves and large veins. Iron is lost by leaching and is held in the lower portions of the soil structure. Under conditions of high pH (alkaline) iron is rendered unavailable to plants. When soils are alkaline, iron may be abundant but unavailable.
Applications of acid nutrient formula containing iron chelates, held in soluble form should correct the problem.
Manganese (Mn) is involved in enzyme activity for photosynthesis, respiration, and nitrogen metabolism. Deficiency in young leaves may show a network of green veins on a light green background similar to an iron deficiency. In the advanced stages the light green parts become white, and leaves are shed. Brownish, black, or grayish spots may appear next to the veins. In neutral or alkaline soils plants often show deficiency symptoms. In highly acid soils, manganese may be available to the extent that it results in toxicity.
Boron (B) is necessary for cell wall formation, membrane integrity, and calcium uptake and may aid in the translocation of sugars. Boron affects at least 16 functions in plants. These functions include flowering, pollen germination, cell division, water relationships and the movement of hormones. Boron must be available throughout the life of the plant. It is not translocated and is easily leached from soils.
Deficiencies kill terminal buds leaving a rosette effect on the plant. Leaves are thick, curled and brittle.

Zinc (Zn) is a component of enzymes or a functional cofactor of a large number of enzymes including auxins (plant growth hormones). It is essential to carbohydrate metabolism; protein synthesis and internodal elongation (stem growth). Deficient plants have mottled leaves with irregular chlorotic areas. Zinc deficiency leads to iron deficiency causing similar symptoms. Deficiency occurs on eroded soils and is least available at a pH range of 5.5 - 7.0. Lowering the pH can render zinc more available to the point of toxicity.
Copper (Cu) is concentrated in roots of plants and plays a part in nitrogen metabolism. It is a component of several enzymes and may be part of the enzyme systems that use carbohydrates and proteins. Deficiencies cause die back of the shoot tips, and terminal leaves develop brown spots. Copper is bound tightly in organic matter and may be deficient in highly organic soils. It is not readily lost from soil but may often be unavailable. Too much copper can cause toxicity.
Molybdenum (Mo) is a structural component of the enzyme that reduces nitrates to ammonia. Without it, the synthesis of proteins is blocked and plant growth ceases. Root nodule (nitrogen fixing) bacteria also require it. Seeds may not form completely, and nitrogen deficiency may occur if plants are lacking molybdenum. Deficiency signs are pale green leaves with rolled or cupped margins.
Chlorine (Cl) is involved in osmosis (movement of water or solutes in cells), the ionic balance necessary for plants to take up mineral elements and in photosynthesis. Deficiency symptoms include wilting, stubby roots, chlorosis (yellowing) and bronzing. Chloride, the ionic form of chlorine used by plants, is usually found in soluble forms and is lost by leaching. Some plants may show signs of toxicity if levels are too high.
Nickel (Ni) has just recently won the status as an essential trace element for plants according to the Agricultural Research Service Plant, Soil and
Nutrition Laboratory in Ithaca, NY. It is required for the enzyme urease to break down urea to liberate the nitrogen into a usable form for plants. Nickel is required for iron absorption. Seeds need nickel in order to germinate. Plants grown without additional nickel will gradually reach a deficient level at about the time they mature and begin reproductive growth. If nickel is
deficient plants may fail to produce viable seeds.
Sodium (Na) is involved in osmotic (water movement) and ionic balance in plants. Cobalt (Co) is required for nitrogen fixation in legumes and in root nodules of non- legumes. The demand for cobalt is much higher for nitrogen fixation than for ammonium nutrition. Deficient levels could result in nitrogen deficiency symptoms. Silicon (Si) is found as a component of cell walls. Plants with adequate supplies of soluble silicon produce stronger, tougher cell walls making them a mechanical barrier to piercing and sucking insects. This significantly enhances plant heat and drought tolerance. Foliar sprays of silicon have also shown benefits reducing populations of aphids on field
crops. Tests have also found that silicon can be deposited by the plants at the site of infection by fungus to combat the penetration of the cell walls by the attacking fungus. Improved leaf erectness, stem strength and prevention or depression of iron and manganese toxicity has all been noted as effects from silicon. Silicon has not been determined essential for all plants, but may be beneficial for many.
How are these elements supplied to the orchids?
In fertile natural conditions these are supplied from the soil but in the case of potting media these may be added by the use of fertilizer and this can be divided into two broad groups.
Organic Fertilisers
They are animal or vegetable origin and generally contain a small percentage of the elements needed. They are slow acting and can vary greatly in their nutrient content.
Organic fertilisers are made from things which were once living, so their nutrient analysis can be quite variable. The great benefit of liquid organic fertilisers is as well as adding nutrients they add beneficial bacteria and fungi as well as some organic matter that helps improve your soil or potting mix.
Inorganic Fertilisers
Inorganic fertilisers are sometimes called synthetic or chemical fertilisers and they worry many gardeners. They're just concentrated forms of naturally occurring minerals. The great advantage of inorganicfertilisers is that you can deliver precise concentrations of nutrients to the plant.
Usually they're supplied as fine powders and dissolve readily in water to give you a liquid fertiliser.
Liquid Fertiliser
Many forms of liquid fertilizer are on the market today which comes with a variety of NPK ratio for different applications. In the growing season from June to March Paphiopedilums love a fertilizer that has a high ratio of Nitrogen Eg N (Nitrogen) 20 P (Phosphorus) 20 K Potassium 20 but in the other months a lower amount of nitrogen.
At the last meeting we had a lot of different fertilisers on display and with a great deal of differences in there makeup of NPK and Colin and Peter discussed some of the differences in these fertilisers.
The fertilisers discussed were:
No Thrills Rock Dust (N. 05, P. 1.0, K. 2.0. Ca. 7.5)
No Thrills Hydrofish (N. 3.1, P. 0.34, K. 0.34, Na. 0.25, Crude protein 19.6, Oil 5.15
No Thrills Seaweed Tonic (N. 0.2, P. 0.16, K. 2.8, Na. 0.25, Crude protein 15.3, Fe. 0.21, Organic Matter 9.0)
Growth Technologies Ionic Grow (N. 2.30, K. 2.89, Ca. 0.95)
Garden Party (N. 6.6, P. 0.85, K. 3.6)

Paphiopedilun Culture Notes (January/February) by Trevor Burnett

The hot weather will be in full swing during these months but I still only water 3 times a week. If the forecast is for very hot weather over 4 days I will increase watering to every 2nd day but always only in the morning.

Keep your additional shade in place if the plants are showing signs of yellowing as they are receiving more light than is required. If plants show any sign of burning add some extra shade for the next few months.

Any burning will cause a setback at this stage which will definitely affect our flowering season. If you have a variety of different size pots, you will need to ensure that the smaller pots do not dry out completely before watering. A simple solution to prevent the
problem of some pots drying out more quickly is to double pot so the pots are all similar size.
By this I mean placing the smaller pots into a larger pot which is filled with compost which encircles the small pot. This way all the pots end up drying out at the same rate.

Paphiopedilum growth should be promoted so keep the regular
fertiliser program in place to ensure the growth mature ready for the flowering season ahead. Let's get back to looking after our plants following the Christmas break, and resume regular routine checking of:

good air movement;
if growing in a glasshouse, misting will assist with maintaining humidity;
weekly fertilising;
not overcrowding our plants;
check for pests and treat if necessary;
keep area clean of dying leaves or material;
increase watering to 3 times a week or more often if plants have dried out;
check all plants to see if there are any signs of stress;
water in early morning before the sun is too high.
