i have heard of people using tree stands to plant in and also nailing/screwing camo painted 5 gallon buckets to the trunks of trees about 15 -20 feet off the ground. seems like a good idea, but you won't see me climbing trees any time soon. i realty like the leaf tip trimming idea, though i don't visit my plants enough to make that a practical technique for me to use, it would be great for the backyard camo garden.
