Abstract

Longleaf pine (Pinus palustris Mill.) and shortleaf pine (P. echinata Mill.) seedlings grew best in equal parts of peat and vermiculite with a low pH. Seedlings grew better in shredded pine cone media than pine bark media. Growth increased when soil or vermiculite was added to cone or bark chips. Commercial bark-vermiculite media with high pHs produced the smallest seedlings: Disease loss was related to drainage and pH. Seedling mortality was greatest in commercial media with pHs above 6.0. Losses, lowest in bark media, increased as the proportion of vermiculite increased.
