Does anyone know of a good (and preferably cheap) supplier of White 50% shadecloth in South Australia for a polytunnel? Will probably need a whole 50m roll.
Alternatively would anyone recommend anything other than White 50 for South Australia? The garden will be in Full sun during Summer, but will likely remove the cloth in Winter.

We use 50% – recommended for SA by some authority somewhere.
Probably Scarecrow 😀
Have you tried places like a hardware store? A rural supplier?
We live in the middle of nowhere and our local Home hardware can get it in as a roll. Make sure you get a good price, though.
Otherwise search online. There are a few suppliers that will sell providing you buy by the roll.
Google is your friend.

I haven’t been able to find many SA based manufacturers, at least not via google. There are hardware stores and rural suppliers, but their prices tend to be more expensive. The price seems to be the larger question! I know the stuff is expensive, but averaged over the warranty (usually 10 years) its not so bad I suppose. Still the more money I save, the sooner I can afford that aquaponics system 😀
I guess I’m being lazy. I figured the less it travels to get to me, the less trees I have to plant to offset the carbon cost!February 10, 2010 at 3:43 am #453181
Ash, I doubt there are many manufactures in SA. How wide do you want it and how much are you being slugged in SA? I have a local supplier who maybe able to steer you in the right direction. Cheers porgeyFebruary 10, 2010 at 3:54 am #453182
After 50% White 3.66m 50m roll. Prices seem to vary but the best quote I have so far is around the $520 mark :tdown: I have just found http://www.shadeaustralia.com.au who will do it for $440 + $35 delivery (QLD company I think).February 10, 2010 at 4:00 am #453183
$475 delivered is a pretty good price but of course it all depends upon durability and longevity. If its manufactured in Oz its probably better than the clap trap they make in China. I would get a sample and see how it goes before coughing up big time. HOWEVER, do you really need any shadecloth? What do you need it for in particular? Cheers PFebruary 10, 2010 at 4:11 am #453184
Will be for a polytunnel over the veg garden. Getting too much evaporation, and everything is getting burnt. Going for the White 50% shadecloth will actually be around a 30% reduction in light & heat due to reflected light. Should get a much better grow, without the burn they are getting now.
Last year I planted sunflowers early and grew everything under them, much better results than this year in which there is just too much sun for most veg (Chillies and Capsicums are doing fine though). But due to crop rotation, I am unable to do that every year.February 10, 2010 at 4:43 am #453185
I have built my Mum a veggie garden and overcame the scorching problem by growing sensitive veggies in the shade of more tolerant veggies similar to your sunflower set up. I found beans, corn, trimmed globe artichoke, potatoes & capsicum really helpful in providing shade for more sensitive plants as well as fruit trees & structures that I grow things up. Moveable potted fruit trees and even moveable potted Jasmine could help provide the shade you require with the advantage of a lovely perfume and use as cut flowers. As for the evaporation, companion planting and dripline has reduced evaporation to almost zero as the water is dripped direct onto the soil and covered by the veggies. There are lots of ways to provide seasonal shade without forking out for shadecloth. I hope that is a help. I will try and post a photo for you.February 10, 2010 at 9:34 am #453186
Hi Ash, not quiet sure what type of shadecloth you are looking for, but Bunnings at Marion have a large variety in varying widths. We used a 98% shadecloth from there for our cat run to help protect our animals, and a 50% one that we use around the tamarillo tree.February 10, 2010 at 10:30 am #453187
Thanks Hopefulls, unfortunately they don’t have a 50% white :shrug:
Coopers at Mylor have apparently found me some (White 50% 3.66mx50m) for $380.00. They don’t normally stock it, but have done me a favour 😀 Wahooo! And with a 10year UV protection warranty, thats just $38/year. :tup:February 11, 2010 at 12:43 am #453188
Ash, thats a great price but I still recommend that you try growing resistent veggies as a screen over a structrure instead of shadecloth. Next summer I am going to grow Scarlet Runner Bean close together and pinch out a lot of laterals to provide both shade, food, and great looking flowers. I tried it this year from saved seed with great success on a small scale and it cost me nothing. I really think you should consider it and save a few bucks. 😀 Cheers P.February 11, 2010 at 2:39 am #453189

Oh Doc you trusty old loyal thing you! :kiss:
The use of 50% white shade cloth in SA is promoted by local Hort media/industry identities; Jon Lamb and Malcolm Campbell (ABC talkback radio), Bruce Morphett from the Adelaide Botanic Gardens, and both the Horticultural lecturers I worked with last year favoured the idea of shaded vegetable gardens!
So see Doc it isn’t just me that finds it impossible to grow anything without shade. :tup:
In the past I have used other plants to provide shade but found they tended to rob the vegetables of precious water here on the edge of the outback.
The wicking beds, especially, need shade cover to lower evaporation levels and prevent any chance of salting of the soil and to keep the wormies cool. 😉
I choose white cloth because the beneficial insects will still visit beneath the cloth whereas I found in my garden that they tended to avoid entering the areas covered with 70% darker coloured cloth.

Ash that’s a great price, it may have a warranty of 10 years but I have shadecloth here (higher shade factor) that’s now over 20 years old and still in one piece! :metal:February 13, 2010 at 7:35 am #453190
Thanks Scarecrow :tup: you hit the nail on the head as far as my patch is concerned with water and nutrients. Actually, if I had only more water, the nutrients would follow also as I’d be able to compost things at a better rate and quality.
I didn’t consider the insect issue, but am certainly glad I bought white now!
Actually I just pulled some green shadecloth off the side pergola as I am going to replace it due to it looking a tiny bit shabby after a branch landed on it a few months ago, and discovered it was manufactured in 1981! So as long as they still use the same material and manufacturing processes I’ll be pretty stoked with my new investment 😀February 28, 2012 at 11:40 am #453191
I bought 50% shadecloth from Bunnings Munno Para. The first time I went they were out of it because of that early hot day – everyone went and bought it. Try ordering it…?

We used shade cloth from http://www.netprocanopies.com for our poly tunnel. They do sell the white 50% on the roll but we used their 15% shade nets which come in 6m x 6m or 10m x 10m. This was a much cheaper option and has proved very effective in keeping the bugs and animals away plus reducing burning and damage from heavy rains.
