Project Information


Note to readers, attached is the complete final report for FNE03-464.

The purpose of this project was to extend the season (on both ends) for organic herb production and find an economically sound method for successfully overwintering tender perennial herbs such as rosemary. Through the use of a permanent 30' X 96' unheated greenhouse and a temporary movable 12' X 96' unheated plastic covered hoop houses we were able to market fresh herbs from April-December. The 30' X 96' unheated greenhouse with two layers of plastic and with additional hooped row covers was successful in overwintering tender perennial herbs including rosemary. To our surprise we were also able to use the overwintering tender perennial as mother plants from which we took cuttings for the production of potted herb plants. We fully adopted the use of an unheated perennial greenhouse for increased herb production, higher quality and longer production season.
