Why are all the pines in New England dying?


  • Since at least 2010 white pines and other conifers have been affected by needle fungus diseases. These are not fully understood but it is believed to be the result of abnormal weather conditions at the time of needle expansion. Most healthy trees will grow new needles after infected ones fall off but these are at risk of infection during wet springs and summers. Overcrowding of evergreens may also contribute to this syndrome. Proper planting and care may help reduce infections.


How will Emerald Ash Borer affect my property

  • The Emerald Ash Borer was discovered in Vermont in early 2018 and in New Hampshire in 2013. It has spread steadily but not rapidly in New Hampshire and new infestations  are expected to be found in Vermont as teams continue detection efforts.
  • This insect is expected to cause widespread damage in Grafton County, NH when it becomes established there. Grafton County has the highest concentration of ash trees in the state.
  • Despite what you may have heard, rapid removal of ash trees from your land will not slow or stop the spread of this insect. It is a slow flyer but it has found its way to new food sources eventually. The movement of forest products is likely the primary cause of new infestations at this point.
  • Some treatment methods are effective and can protect trees for at least two years before re-treatment. In most cases, treatment is far less costly than removal and replacement of currently healthy landscape or municipal street trees.
  • The best local sources for reliable information and management recommendations are: www.vtinvasives.org and www.nhbugs.org

Are big trees hazardous?

  • Big trees, and any other large upright structures, can not be made to be free of all risk. But trees are biomechanical structures that have adapted to loads and forces as they have grown. Healthy, sound trees can be managed by experts to reduce risks to acceptable levels in many cases.

Do trees need fertilizer?

  • Fertilizer provides supplements that are used by plants for essential processes such as photosynthesis. Trees in the forest usually have access to these elements through natural re-cycling of leaves and other matter. Trees in the manicured landscape do not have this benefit. Tree fertilizing should only be done according to soil analysis to determine actual needs. Prescriptive soil treatments, combined with good maintenance practices like wood chip mulching can be helpful to ornamental and crop producing trees.
