I built a shade house about 16-18 months ago:
About six months ago I started to notice white spots on my plants. I feared the worst and thought I had some type of pest, but closer inspection revealed that it was small pieces of the shade cloth. Unfortunately, it has begun to deteriorate rapidly. It rained pretty heavy yesterday and it looked like snow on the plants.
I know this isnít a very good picture, but I hope you can see how the shade cloth it coming apart.
So, is this normal? How long does shade cloth normally last? How tightly should shade cloth be stretched over a frame? I am now wondering if I contributed to this by stretching the shade cloth too tight (hoping to keep it from blowing around in the wind). Any thoughts or suggestions would be greatly appreciated.
