Membership meeting Wednesday, March, 11

Fertilizing Roses

Presented by  Karen Anne McCann 

7:00pm in the Community Room 

 Dublin Library  

 200 Civic Plaza, Dublin 



Karen Anne is a Past President and currently Vice President Programs and Membership Chair of the North Bay Rose Society in Vallejo, and was awarded the Bronze Medal in 2018. She is a Master Consulting Rosarian, and she has written extensive articles. Karen Anne was honored as the District Outstanding Consulting Rosarian in 2021. 

She grows 102 roses in her small back yard and has won many awards for arrangements as horticultural entrees over the past 38 years of being a member of the ARS and North Bay Rose Society.  Karen Anne worked as a private gardener for 14 years until she had to quit to receive a new knee...another new knee...a new hip...another new hip...a new shoulder...and another new shoulder.  That's what happens when you work too hard.  But she really enjoyed the job and still does maintain her own rose garden and consults with others.

Emerald Glen Rose Garden Prunathon

The Annual Prunathon of the Emerald Glen Rose Garden is complete! 


The 167 roses are now a Winter Wonderland of tidy, sculptured plants ready to burst into Springtime bloom. Pruning is finished for 2026! .  

Why does MDRS prune the garden and deadhead it during the growing season?  Because the City of Dublin provides us with a free meeting room in the Dublin Library.  Last time I checked, it saves us $200 to $300 per meeting.


Many thanks,

Kathy Knabke - The Grateful Deadheader (and Pruner / Raker)


Thank you to the many members that helped prune and rake during the Purnathon: 

Heather Brillhart, Nicole Duemmlein, Linda Nardy, Sheryl Reed, Elizabeth Wiener, Peggy Carlson, Lou Evans, Andy Miller, Cathy & Charlie Ruberta, May & Tun Lee, Helen Zawlik-Moyot, Andrew Mays, Susie Chan and me.
