You mean, where did i come up with these statements?
I've practiced with a 10 yr old nursery juniper and tryed to see how much foliage i could remove at a time and i found out that the tree survived after i pruned 50% of the foliage.but this should be done only once and make sure that the tree gets very good growing conditions afterwards as it is really stressed due to that foliage loss.The 20% foliage reduction is the maximum i would go for an unhealthy tree.
