CELEBRATING OUR 25TH ANNIVERSARY
When I started out to do this write-up in celebration of our 25th anniversary, I wondered if it was worthwhile reprinting some of the material which I included in our January 2012 issue of Newslink for our 20th anniversary. But, on counting up just how many new members we have signed on during these past 5 years, I found that the figure is close to fifty. So for some of our newer members who may not be aware of how our Society began I will extract a few paragraphs, just to fill you in.
It all began after an article appeared in the Advertiser newspaper to let Illawarra residents know of the possibility of starting up a local bromeliad society in the area. This article had been at the instigation of Merv Henderson, a member of the Bromeliad Society of New South Wales, whose dream it was to introduce more people along coastal New South Wales to the beauty of bromeliads. And so it was that on February 1, 1992 about 20 people met at the Education Centre of the Wollongong Botanic Garden to discuss this proposition. Tremendous support was also given by other members of the New South Wales Society, many of whom travelled down to stage a very beautiful exhibition of bromeliads in readiness for the visitors who would attend the meeting. It was apparently a most inspiring, friendly and successful occasion and Merv’s aspirations were fulfilled as the Illawarra Bromeliad Society was formed, the inaugural meeting being held on March 7, 1992.
Margaret Bartley, our first Secretary and current Lifetime Member (her husband, Jeff [now deceased] was our first President) remembers those early days as fun and exciting, with a core group of people working together to get things off to a flying start.
This fledgling society, in its first year, participated in the Florawarra festival (an event held each October at the Wollongong Botanic Garden) as well as putting on displays at the Corrimal Shopping Centre and Shellharbour Square and, during its second year, our Society was invited to participate in the Wollongong Horticultural Society’s Autumn Show as well as Florawarra. Also there was liaison with Steve Popple, then curator of the Wollongong Botanic Garden, to have the roof of the glasshouse replaced and a donation of bromeliads by our Society for display in this structure, as well as to start a bromeliad section in the garden outside. Also during this second year for our competition table a trophy for most points was introduced, with dear Dulcie Doonan being the first winner.
In 1998, when Florawarra became no longer viable and had to be cancelled, an invitation came from the Corrimal Chamber of Commerce to take part in the “Spring Into Corrimal” festival and with their help we found our new location which we have used every year since—the Uniting Church Hall in Russell Street, Corrimal.
The year 2001, however, was a milestone year for our Society for in October we hosted Brom-A-Warra, the 11th Conference of Australian Bromeliad Societies, at the Sea Spray Function Centre in Shellharbour. The cover picture on this issue of Newslink was the logo used for the Conference and was designed by John Killingley.
When membership increased to the point where we needed a larger venue for our meetings we moved in February 2007 to the Dapto Ribbonwood Centre where we seem to have gone from strength to strength. But I think that a sign of just how successful and friendly our Society has been is that we still have 4 of our inaugural members participating, as well as many others who have been with us for twenty years or so.
But we haven’t been “resting on our laurels" and in recent years we have arranged for workshops to be held at members’ gardens several times a year where it gives newer members—as well as more long-term members and visitors—an opportunity to meet on an informal basis to learn some of the basics of bromeliad growing such as separating pups, potting up, potting mixes, fertilisers, mounting, etc. etc. We have also arranged garden visits—at least three a year—and these are immensely popular.
Technology has played its part, too, as our Newslink now goes onto the web (www.bromeliad.org.au), reminders and updates of upcoming topics and events are emailed to our members, and, most recently, Michael Drury has been working very hard to scan and put all of the previous copies of Newslink onto USB sticks which members will be able to borrow from our Library. Power Point presentations are also now easy and popular, using the Society’s laptop and projector.
Ours is a fortunate Society, I believe, as we have always had that willingness and commitment from our members to make it the friendly and interesting forum that we have today, and I am confident that we can look forward to many more years and anniversary celebrations.

WHY HUMIDITY IS IMPORTANT TO PLANTS
(Reprinted from Bromeliad, J. Brom. Soc. New Zealand, March 2007, 47(3)
All plants inhale carbon dioxide through their leaves. This gas is used in photosynthesis. As the plant opens its leaf pores to take in carbon dioxide, some of the moisture in the leaf can escape; thus the plants sweat water vapour into the air whenever they breathe. Dry air causes plants to transpire moisture much more rapidly than humid air. Water in the leaves evaporates very quickly into air, causing the plant to lose moisture at a rapid rate. When leaves begin to lose water faster than the roots can absorb it, disaster strikes in the form of self-defence. In order not to lose more water to the air, the plant will almost completely close its leaf pores. This slows down the flow of moisture from the plant effectively. But, unfortunately, it also reduces the intake of carbon dioxide. Without carbon dioxide, the cells begin to die and the plant looks tired and ill.
The important point to remember is that dry air pulls water out of the leaves faster than the roots can supply the leaves. Under these conditions it does not matter how much you water—it does not help. Overwatering only reduces the amount of air in the soil and invites root rot.
When plant have the right humidity they thrive because they open their pores completely and so breathe deeply without threat of excessive water loss. When the air is moist there is little water loss from the leaf. Damping down the benches and surrounds, also misting leaves, will help keep the air moist. Rapid temperature rise damages plants too. It means that the plant’s leaves become warm and physiologically active, while the root system in its solid rooting medium is still cold and physiologically dormant. The active leaves are demanding large quantities of water and nutrients, which the root system cannot possibly supply. Under these conditions photosynthesis, transpiration and other vital plant processes are severely restricted and, as a result, developing flower growth and new growth are damaged. Rapid rise in temperature on sunny days can be avoided by opening vents or doors early in the morning and letting the greenhouse warm up gradually.
A humid atmosphere that is not moving is also particularly undesirable. Damp, stagnant conditions encourage mold and bacterial diseases. A constantly moving, light, and buoyant atmosphere keeps plants vigorous and healthy.
MAX WILLIAMS’ CRYPTANTHUS TRAY
At our August 2016 meeting Max showed us how he grows his cryptanthus, and using this method has succeeded beyond expectations for him..
You will need:
- 1 x 35 cm dish, plastic terracotta
- 1 plastic dish about 2 cm smaller than the larger dish and drilled with 8 mm holes
- Wicks--as many as the holes—cut from cotton fabric into strips 8 cm long
- Peat moss/Coir Peat/and Perlite – available in 5 litre packs from Flower Power
- Coir – Perlite mix
- Peat Moss
- Wicks and polystyrene
Step 1: Drill smaller dish with 8 mm (1/4 inch) holes and thread in wicks 8 cm (4 inches)
Step 2: Place a few small pieces of polystyrene to keep the dishes apart
Step 3: Place some peat moss across the base over wicks, not too deep
Step 4: Mix 4 parts coir peat with 1 part Perlite and spread over peat moss
Step 5: Add plants as wanted and tuck more mix over roots of plants
Step 6: Fertilize with 1 g Manutec’s Orchid Bloom Booster or Neutrog’s Strike Back for Orchids to 1 L water once a month and spray every 2nd day with a weak solution of Seasol
HOW TO EASE SUNBURNT BROMELIADS
By Paul Turvey 2015
(Reprinted from the Far North Coast Bromeliad Study Group NSW’s December 2016 and January 2017’s Newsletters)
A response by Paul to a sunburnt bromeliad query on a forum:
I reckon you’ve done extremely well to only get that much damage! Well done indeed. Apart from a bit more misting, the only other thing I can suggest is a bit more nitrogen in the fertiliser, or, if the pH of your water is alkaline, something added to it to bring the pH back to neutral or slightly acid. This is something I’m trying myself since I have a few vrieseas that routinely do this.
Low nitrogen levels can increase susceptibility to burning (established scientifically for at least some bromeliads) and this would occur especially in leaves that don’t produce a red/purple sunscreen—e.g., plenty of foliage vrieseas. Nitrogen shortage in older growth can result if a plant is pushing all of its nutrients into new growth (which is what they seem to do) and there isn't enough nitrogen available to support the whole plant. This overall shortage might just be because there isn’t much nitrogen fertiliser in the medium or in the water, but it can also occur if there is plenty of nitrogen fertiliser but the pH is also high—i.e., up above 7.2 or so—because as the pH gets up much above that (my tap water has pH = 7.8), the bromeliads’ mechanisms for taking up nitrogen fertilisers do not work. So, they get starved of nitrogen by the high pH even though there is plenty of nitrogen fertiliser around. I have no idea if this might apply to you or how it might work in your situation, but I thought I’d mention it since it’s something I’m giving a go for my bromeliads.
Certainly, in my case, I’ve established that I get much more growth using the same fertiliser mix and concentrations if I acidify the water to bring it down from 7.8 (quite alkaline) to about 6.5 (slightly acidic). I think I’ve made a few good inroads on the leaf-tip burning and die-back, but I’m still getting a bit.
Calcium hardness of the water is also something that has been linked to leaf damage in vrieseas. My current plan (just starting) is to use citric acid rather than other acids to bring the pH of the tap water down, since citric acid also chelates the calcium in the water so it can be used to eliminate calcium hardness. Do you have hard, limey water—which is very possible in your area? That could also be a contributor affecting just some vrieseas.
Hope this helps.
Update – by Paul Turvey 2017
Update January 2017: Still as previous article (FNCBSG NSW Dec. 2016) but now with some solid results using citric acid. I’ve done this now with a thousand or so seedlings continuously for up to two years starting from germination, with a hundred or so bromeliads in one shade house for a year, and with all the hundreds of bromeliads in the garden for the last 6 months. All of them show the best growth ever for me, especially the seedlings, and with the least leaf-end die-back on the few sensitive vrieseas.
Some bromeliads like Aechmea chantinii are doing fantastically better with the green clones developing a beaut dark green to show off the silver stripes. A bunch of different clones had always struggled to get much more than greenish-yellow before over quite a few years regardless of fertilising, so I suspect the abrupt change is a pretty sure sign of what was general nitrogen starvation that has now been corrected by the citric acid in the water.
I’m still getting a bit of leaf-end die-back on a couple of the most sensitive vrieseas but these were long-established plants that would have had a build-up of non-chelated calcium before I started the treatment. I’ll have to wait until I can grow new pups on the water + citric acid diet before I make my mind up about those.

Maureen Wheeler (Reprinted from Illawarra Brom Soc. Newslink January 2004)
I found that I was running out of floor space for my bromeliads in my shade-cloth covered pergola and as I had little fence space (and all the commercial pot holders were either too big or made for solid walls) I decided to make my own support.
I employed a piece of steel reinforcing mesh about 1.3m wide x 2.1m long as a frame, and used 1.57 gauge galvanized tie-wire to form holders for the pots. I made a noose around the top of an old squat pot, with enough allowance to extend to the bars, and then put a smaller piece of wire through the bottom of the pot to hold it taught (see diagram and photo below). Then I put my plants (which were in their own pots) inside the squat pots. You can customize the spacing of the pots to allow room for long-leaved plants, and, by using this two-pot method, it allows for easy turning or removal of your plants.
