Several conifers work well as windbreaks. Canadian Hemlock works in zones 3-7.
Dear Flora,
We recently tore down an old barn just west of our house and now realize that it had provided a nice windbreak. Can you suggest some trees suitable as a windbreak replacement? – Indiana Homeowner

Your Indiana soil is probably fairly sandy, so sturdy pine trees would be suitable and tolerate heavy winds. Jack Pine, P. resinosa, is adaptable as needed for windy, open conditions although not the most attractive of trees.
Red Pine, P. resinosa, is often used in windbreaks for its dense foliage and more attractive symmetry.
If appearance is of concern try Tsuga Canadensis, the Canadian Hemlock which grows fairly fast for a conifer, or Taxus cuspidate, a yew species that is tolerant of cold temperatures and can be shaped by pruning.
Keep in mind that a windbreak will provide 20 times its height, so a 10-foot tree can be planted about 200 feet away for effect. For appearance, I recommend a group of 3, 5, or 7 trees with adequate room to spread.
