Winter time is somewhat of a downtime for deciduous trees. After a growing season’s worth of beautiful foliage, culminating in the wonderful fall display of color, woody plants enter the long, cold season of dormancy that is part of their annual life. For many of us, this is not a time...
Everyone has their own idea of the perfect Christmas tree. While I am not a person that picks the proverbial “Charlie Brown Tree”, I have certainly felt pity on the less attractive trees on the lot in years past. Whatever your taste, a fresh cut Christmas tree adds a certain bit of...
