One of the best things about a summer morning is stepping out your door, breathing in the fresh air, and admiring the beauty of a perfectly kept yard, complete with impeccably trimmed trees. Of course, while people love the pruned trees, they don't often think about what it takes to keep the trees that way. Interestingly enough, proper tree maintenance isn't as simple as taking a pair of pruning shears and cutting off the excess branches.
Evergreen trees, such as pines and firs, make a wonderful addition to your garden, providing colour and interest all year round. Many species of small birds also make their home in the bushy shelter of evergreens, bringing your garden to life.
However, if you notice brown, dead needles at the top of your evergreen trees, there could be a serious problem. So what causes browning of evergreens and what can be done to fix it?
