Replanting After Pine Wilt

After the removals and clean-up from pine wilt’s damage, there are excellent opportunities to continue beautifying your park, school, yard or library: Replant! Below is a list of replacement trees, suitable for Oklahoma, as well as some important characteristics of each.

Pines

  • Shortleaf pine – native to eastern Oklahoma , hardy, moderately dense crown, available in limited supplies from nurseries
  • Loblolly pine – native to eastern Oklahoma, avoid planting in high clay soils, open crown, easily found in nurseries
  • Ponderosa pine – native to western US, it has transplanted well in Oklahoma, moderately dense crown, available in limited supplies from nurseries

Note: The listed pines have a different growth pattern from Austrian and Scots pine. Shortleaf, loblolly and ponderosa pines do not keep their branches to the ground; they have a more “open” appearance than the dense growth of Austrian and Scots pines.

Other evergreens

  • Junipers, improved varieties – native to Oklahoma, aesthetic varieties of eastern red cedar, hardy in almost all soils and locations, drought tolerant, don’t spread indiscriminately, many varieties and cultivars available from nurseries
  • Arborvitae – successful introduction to Oklahoma, prefers soils without high clay content, dense branching and foliage, should not be planted near trees or shrubs with seridium canker, available from most nurseries
