A word of caution here in reference to the use of manure on 
rhododendrons. <A good general rule is, don’t. If you cannot 
secure old leaves for the mulch, it is better to top-dress them with 
old well-rotted manure, preferably cow manure, than to leave 
them without mulch of any kind. But to be sure that it is old 
and well-rotted. Fresh manure is fatal to them. If at all 
possible secure old leaves or leaf mold, for this is nature’s own 
way of doing it, and it cannot be surpassed. 
A word as to the protection afforded by group-planting. Many 
trees and shrubs may be cultivated in this manner which would
