A recent study in Thailand finds that raising native tree seedlings inside repurposed bottle crates improves performance compared to standard methods in community-run nurseries.
Saplings grown in bottle crates had better root formation and superior growth when planted out in a deforested site, thanks to better air circulation for the roots.
Crating the saplings also saved on labor costs, which more than offset the cost of purchasing the crates.
Adoption of the new method could improve the quality of saplings grown in community nurseries, a benefit for reforestation projects where sapling survival is key to success.
