Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
Gardener's Help Desk Request: What should I use to seal rose canes after pruning? Is a dot of Elmer's Glue OK, or is something else more effective?
There is no need to seal the pruning cuts of your roses with Elmer's Glue, or any other product. Rose canes will seal themselves, especially if pruned during their dormant season, roughly mid-December to mid-February at a 45 degree angle. If you have added any sealant, you would be better off re-pruning those canes.
Here is a link to a UC Master Gardener guide to rose pruning, including a chart about “Rose Care by the Month”, that you might find helpful. http://ucanr.edu/sites/mgslo/files/272360.pdf
Please do not hesitate to contact us again if you have more questions. And here's to a great rose year in Contra Costa County.
