In an effort to keep members informed during these unprecedented times, we will be publishing various articles to keep you up to date with all things orchid. Unfortunately, we cannot have our usual meetings, but we can keep in contact with each other via the wonders of the internet. See below links to articles that you may well be interested in. And, if you have something to add, short articles that you would like others to see, comments on articles already on line, or anything at all that you would like to see on line, just email me at waos@iinet.net.au and I will be happy to oblige.
For a start, here is a great article on growing Standard Cattleyas in Perth by Bruce. Click HERE to see the article in Word.

ALL MEETINGS HAVE BEEN CANCELLED UNTIL FURTHER NOTICE

Due to the Corona Virus the WJOS Committee have decided to cancel all meetings while there is the danger of contagion. This step has been taken reluctantly but it is felt that we are better to err on the side of caution than risk our members becoming infected. We are sure that members will understand the necessity for this measure.

Please watch this space and be safe.

The Importance of Water and Fertilizer.

http://www.waorchids.iinet.net.au/The_Importance_of_Water_&_Fertilizer.pdf

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

Calcium Deficiency Symptoms:

Calcium deficiency has a similar appearance to a bacterial or fungal rot, but is really the same problem as blossom end rot in tomatoes. It affects cattleyas, especially the Guarianthe, primarily during periods of rapid growth.
Calcium, a lesser macronutrient, is used to build cell walls.
 
Deficiencies usually occur in spring and summer during periods of active growth. New leaves may turn black at the tips. The affected area has an advancing yellow band. Bud growth may be inhibited or buds may develop improperly. A calcium deficiency may also cause death of root tips. (extracted from Orchid Species Culture by
Margaret L. and Charles O. Baker) Treatment: 
Supply extra calcium when the plant is in active growth. Use a good cal mag fertilizer, add calcium nitrate at the rate of 1/4 to 1/2 teaspoon per gallon to your water (alternating with Epsom salts) between fertilizations, add 1 tablespoon of dolomitic lime per gallon or top dress with powdered dolomite as a source of calcium and magnesium during the hot months when calcium requirements are high. You can also make the calcium present in well water more available to the plant by using an acidity generating fertilizer like 20-10-20.

Prevention:  Supply extra calcium via a good cal mag fertilizer, calcium nitrate or dolomitic lime.

A Note To Novice Growers
Please don't be afraid to bring along to the meetings, any orchids that you have in flower. Members will be more than willing to assist you in understanding how to improve your orchids. That is what the Society is all about. Our purpose is to help orchid growers, help orchid growers
We are not there to ridicule or embarrass our newer members. Quite the opposite. We want to help you improve your orchids so that you can become better growers yourselves.

Paphiopedilim Culture Notes February/March
By Trevor

These are months that the weather can usually be expected to have some excessively hot days. At this time of year, I water 3 times a week early in the morning with overhead sprinklers, so the plants are well
saturated.
This will allow time for the plants to be dry before the sun gets too high and will prevent any possibility of water burn. This will also ensure plants are dry before nightfall. Some growers may be tempted to water on hot evenings but I personally avoid this at all
cost.
 
Water left in the axils of the leaves at night only encourages rot and water borne disease. I find if the plants are watered
heavily the next morning they seem to thrive on the fact they have been forced to dry out somewhat overnight. If excessive heat is forecast over consecutive days, you will need to watch plants in small pots and increase the watering as necessary. Watering is highly dependent on the composition of your potting media and its ability to retain moisture (For beginners, a test pot of plain potting mix in the growing area is recommended until you
understand the water holding capacity of your mix - you can empty the pot at any stage to see how much water is retained.
 
The pot should be just moist throughout the bottom half of the pot.) As the plants are still in active growth, keep a weak fertiliser program going on a weekly or fortnightly basis depending on your time constraints at ¼ to ½ strength with a high nitrogen-based fertiliser to maximise the new growths before the flowering season.
 
Ensure that you flush the pot with water between fertilising which will flush out any excess salts. In the glasshouse, the use of misting sprays under the benches will be beneficial by
increasing the humidity levels on very hot days. It is equally
important that plenty of fresh air, which is essential for the plants health, is available in the glasshouse. Do not remove any extra shade that you may have installed over the summer months

A message from The Water Corporation

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

Magnesium DeficiencySymptoms: Magnesium deficiency can result in cupped leaves, a reduction in growth and marginal or interveinal chlorosis (yellow along leaf edges or between veins) and usually is exhibited in the middle or older leaves (extracted from Orchid Species Culture by Margaret L. and Charles O. Baker)Plants grown with a magnesium deficiency can exhibit chlorotic mottling after exposure to extremes of temperature. When growth begins in the spring, the older leaves on plants grown without sufficient magnesium will yellow and drop as the plant translocates magnesium to the new growth.
 
Dr. Martin Motes suggests an increase in anthocyanin (red/purple coloration) in leaves, particularly after exposure to cooler temperatures, can occur as a result of magnesium deficiencyTreatment: Supply extra magnesium when the plant is in active growth. Use a good cal mag fertilizer, add Epsom salts at the rate of 1/8 to 1/4 tsp weekly or 1/2 teaspoon per gallon to your water each month, add 1 tablespoon of dolomitic lime per gallon or top dress with powdered dolomite.

Prevention:  Supply extra magnesium via a good cal mag fertilizer, Epsom salts and/or dolomitic lime.
