Consulting Rosarian Tips for October:

by Mary Kirby

As this year’s gardening season draws to a close we look forward to turning our attention to next year! These warm September and October days are great for getting the tasks done that can help reduce disease and pest problems (also work) next season. We all know that it will be snowing and blowing soon enough and that makes these last of the season days spent in the rose garden so enjoyable.

This year the end of summer has been very dry. A regular weekly watering schedule is important under these conditions. Be careful not to over water as the plants need to harden off for winter dormancy. Balance is important. It is also important to deep water before a predicted hard frost to minimize root damage from dry soil if possible.

If you experienced mildew or fungus problems, remove, bag and dispose of infested leaves and shoots including any plant material on the ground. Do not compost! Good fall clean up and sanitation will be very helpful with controlling pests and diseases next season.

Removing spent blooms will encourage new growth which is to be discouraged so it is best to only remove the petals or clip off the bloom just below the flower.

Be vigilant in snapping off any “basal breaks” coming up from the base of the plant. The “basal breaks” so welcome in the spring are not good in the fall. They will not live through the winter and will sap the bush of much needed energy.

Winter mulch should be added to your garden after three consecutive nights of twenty-two degree weather but before we reach single digits.

Finally, it is a good time to assess the roses in your garden. Do you have roses that don’t produce enough quality blooms? Would a particular rose do better in another spot? Are you just tired of some? Would you consider shovel pruning them? Dig new holes and amend the soil in preparation for any new spring additions if possible. It is almost time to spend the winter googling, perusing and dreaming of new roses for next year.

For rose questions, contact a Consulting Rosarian in your area.

2015 Roses in Review

Every year, the American Rose Society conducts a survey of roses and how they grow in gardens around the nation.  The national results will be published in a future edition of the American Rose Society magazine.  The results for the Rocky Mountain District (Colorado, Idaho, Montana, Utah and Wyoming) are available now!  The first file contains the results sorted by variety, classification, garden rating and exhibition rating.  The second file contains the comments provided by the reviewers.   



The book, Growing Roses in Colorado, published by the Denver Rose Society is a "must have" for those who want to grow beautiful roses successfully.  Get a glimpse inside the newly revised Growing Roses in Colorado.  Available at area garden retailers and gift shops. For wholesale inquiries please contact Betty Cahill at
