uses for CDs? [Dec. 30th, 2011|12:59 pm]
Organic Gardening - Flowers, Fruits, Vegetables


I've heard of (and seen) people hanging strings of old CDs around fruit trees to protect the fruit from birds - the reflections are supposed to scare them off.  Does it work?  How thickly do they need to be strung?  How high/low would they need to be to protect the tree top-to-bottom?

Also, has anyone tried placing an old CD (shiny side up) as protection around a veg seedling?  For example, a squash or melon?  I ask because silver reflective mulch is supposed to reflect light onto the undersides of leaves and deter some pests - would a CD be sufficiently reflective?  Could it also work as a sort of cutworm collar?
The CD-around-seedling idea is just one that came to mind this morning; I'm not sure if it would be at all useful.  I don't see references to such an idea online, so figured I'd ask if anyone had tried such a thing.
Possible drawbacks that come to mind:  not water-permeable, so would create a dry zone; contains silver...although hopefully that can't leach out and is only a problem if it melts; could get splashed with mud and then wouldn't be reflective anymore; slugs might hide on the underside.  Thoughts?

The cds are an upscale replacement for pie tins, which have been used this way for ages to scare deer and birds, who don't like the reflective surfaces. You can also use mylar balloons if you have any.

I'd be concerned about strangling the plants if the stems got too thick or possibly burning the undersides of the leaves before the plants leafed out enough to shade them. I'm not sure they'd offer much protection against cutworms or other bugs. Still, no harm trying a few and reporting back with your results.

Maybe break the CD in half and tape it back, so you could open it more if the stem got thicker?
