As I continue planning my landscaping, I intend to add more pines. They're relatively hardy trees and provide fantastic cover, not to mention being attractive in all seasons. Birds can nest in them, some birds will eat the seeds, and they don't require too much maintenance (and no raking for the short-needled varieties!). At this time of year, they provide critical shelter, so long as you do continue to care for the smaller varieties. Just today - as I was refilling my front yard bird feeders - I took some of the iced over snow off the mugo so it would straighten up, fluff out, and be better shelter than an icy pancake. Larger pines and mature trees, of course, don't need that type of quick care and are perfectly usable even in the harshest winter weather or deepest snowfall.
For now, I'm happy that my pine trees can entice my shivering flock to safer shelter, and they're welcome to decorate it anytime.
