Branched plant props

Spreading, frond-like, and yet thin spray, such as that of the beech, hazel, or Scotch elm, is generally preferable; but for early crops the spray of the resinous tribe, and especially of the spruce and silver firs, is valuable, as producing warmth and shelter, by its numerous chaffy leaves, which are non-conductors.
