  • Location: St. Vrain Memorial Building
    700 Longs Peak Ave.

  • Introduction: Please come help with some early season pruning in our City's beautiful Memorial Rose Garden, located by the St. Vrain Memorial Building.

Out of an abundance of caution due to COVID-19 (coronavirus), the City of Longmont has decided to cancel this program. Thank you for your support and interest in our programming.

Please come help with some early season pruning in our City's beautiful Memorial Rose Garden.

Colorado winters are harsh and can cause extensive die back in the rose garden. At this event, volunteers will use loppers and clippers to prune hybrid tea and grandiflora roses almost to the ground. This is not your typical pruning! With 56 garden beds, this work usually takes staff 8-10 days to complete each season. With your help, we hope to accomplish a lot of this technical pruning in just one, short morning.
