Here is a question: what do you use to attach foliage to SuperTrees? I have been using unscented hair spray which I find very easy to use. My question concerns longevity: will this last a long time? I don't want to plant hundreds of trees and then 5 years later have the scene turn into winter as leaves fall off. On the other hand, the trees I put in maybe 3-4 years ago using hairspray seem to be lasting just fine, but I figure some TRW members have more years of experience than do I. So, should I keep using hairspray or switch to something else? Thanks! Bob
