Long Needle Pine
Watch for
Long needle pines are interesting pine trees in the way that they do not resemble a traditional Christmas tree.  They are much less full than a typical pine tree like a blue spruce.  The way to tell them apart from most of the other pine trees is their long needles and long skinny cone.  They are very nice trees that grow quickly and unlike most pine trees they do not often fall in high winds.  That is because they are sparse.

The long needle pin does have a serious pest that infects it and does damage like the pine pictured on the top right hand side of this page.  This borer causes much damage to the tree and is sought out by the Minnesota Department of Agriculture.  The beetle itself is harmless mostly feeding on the needles.  The larvae of the beetle are the ones that do the damage.  They eat the living area of the tree and do there damage by not allowing nutrients to make its way up the tree.

Other diseases in Long needle pine include leaf blight.  This fungus disease causes the needles to turn yellow. Rust scale is orange in color and can also be found on the needles of this tree.
Here are some things to look for in your Long Needle Pine:

  • Needle discoloring
  • Needles turning yellow or rust color
  • Die out in sections of the tree
  • Holes in the bark
