Habitat: Hardy from zone 2 to
6, the European larch prefers moist, well-drained soils or deep,
fertile soils overlying limestone or sandstone. It grows well on moderately
calcareous soils, but is intolerant of dry, shallow, highly calcareous soils,
compaction and drought. Trees require free circulation of air and a sunny
position.
Diseases: This larch is relatively
free of pests and diseases, although canker may be a serious problem. Woolly
larch aphid, larch sawfly, needle rust and larch casebearer sometimes occur.

Distribution: The European
larch is native to the Alps in central Europe from southeast France eastward
to Vienna. It is widely planted in Europe and the US and is the only deciduous
conifer commonly planted in Iowa. |
