Consulting Rosarian Tips for September:
Continue disease prevention activities.  Mildew which shows up a grayness on your leaves, has been especially bad this year.  Spray your roses and the surrounding ground with fungicide to kill spores before winter.  Mildew spores can live over the winter and weaken your plants in spring.   Continue to reduce watering so plants can begin their hardening off process in preparation for dormancy.  When removing spent blooms, cut just below the bloom so as not to stimulate new growth which would be injured severely by early freezes.  Definitely remove any basal breaks starting to grow so as to prevent freeze injury to the bush. 

Consulting Rosarian Tips for October:
Deep water prior to predicted hard freezes to lessen damage to roots which could occur in dry soil.  Remove any blooms just below the flower.  Do not fertilize your roses.  Take time to plan and prepare new roses beds.  Spade or rototill new beds deeply, mixing in organic materials and let lay over the dormant season.

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