Plastic Posts

The last few days in Marlborough have been scorchers, with daily maximum temps over 30 degrees Celsius.  While I’ve been moaning about being hot, pregnant and trapped in stuffy upstairs classrooms packed with teenagers, I think Aaron can give me a run for my money on the sympathy vote.  He has been out in the vines (add around 5 degrees!) trying to upright heavy rows of vines that have simply fallen over with the weight of the fruit and foliage.  The cause: plastic posts.


In the past, all the posts in the vineyard were treated timber but there has been a move away from these due to issues about chemicals – including arsenic –  leaching into the soil (although the results showed it didn’t go very far from the post base).  However there is also the issue of the disposal of broken or old posts.  Posts occasionally get broken by mechanical harvesting or tractor work, and because they are chemically treated they cannot be burnt or buried.  And if vineyards are pulled out (not entirely unlikely at the moment!) there are a pile of posts left with nowhere environmentally safe to go.  Some have found creative solutions recycling the posts into anything from sheds to garden furniture.   Anyway, a better solution was touted as being … plastic posts.   How successful are these posts?  How well tested were they before being sold to viticulturalists with an environmental conscience?  The pictures say it all… them and the sounds of Aaron’s language which may well have been heard quite widely! We can only be grateful for my Dad’s wisdom in  alternating the new plastic posts with the traditional wooden posts – this has kept most rows standing.

    I bet that wasn’t in the ‘plastic post’ brochure? I hope you don’t get too much damage, and it cools down a few degrees (would be good for us all).

    Have you guy’s tried the steal posts. That photo reminds me of results from those really rubbish treated wood posts that were around during the kiwifruit boom.

    I think a few years ago there was a bad batch of wooden posts around here too. Spindley little things.
