There are clues that indicate if a tree is in danger. If a tree has large branches attached with tight, V-shaped forks, you should consider having those branches removed or trimmed. Other warning signs of structural instability include cracks in the trunk or major limbs, hollow and decayed areas, or the presence of extensive dead wood. In addition, mushrooms growing from the base of the tree or under its canopy may be a sign of root decay.
Be cautious of any tree that has had construction activities such as trenching, addition or removal of soil, digging, or heavy equipment movement anywhere under the spread of its branches. These activities can cause root death, which in turn could lead to structural instability.
Even a healthy and otherwise safe tree can become hazardous if it grows close to electric power lines. Someone who touches or climbs a tree while it’s resting on a live power line can be electrocuted. Any tree that has limbs within 10’ of overhead lines should be considered hazardous, and should be left to the professionals.
What's the Best Season for Tree Care Work?
Many tree care activities can be carried out all year long. For other activities there is a season. Spring and summer give us the best opportunities to identify tree health problems, since a cursory inspection can tell whether the tree "looks" healthy compared to previous years or nearby trees of the same species.
Diagnosis of the actual cause of the tree malady is a tricky business best left to an expert. As with human illness, prompt detection and treatment can be critical. Most pest management activities have a very specific and narrow window of treatment that coincides with when the pest is active on the plant and/or vulnerable to the treatment.
Fertilizers are best applied when the plant roots can actively uptake the nutrients. Of course, the use of fertilizers on shade and ornamental plants should be restricted to situations in which there is a nutrient deficiency. Some will argue that, in temperate areas, fall and winter are the best times to prune. When the tree is bare, its branch architecture is easier to observe, so problems can be more readily corrected.
Proper pruning at other times of the year will generally do no harm to trees, but there are exceptions. For instance, pruning an American elm when the beetle that carries Dutch elm disease is busy flying from infected to healthy host trees greatly increases the elm’s chances of infection. Pruning of deadwood only does not have the same effect and can be carried out any time. Scorched leaves My tree's leaves are brown on the edges! It's most likely a cold injury or "leaf scorching," caused by insufficient water transport to the leaves. Give your tree a lot of water during dry periods, and check for possible root damage.
