Rosa Rugosa Help Needed
So I just moved to a new house and I found that two of my Rosa Rugosa's need help but I am not sure how to help them.
This week I am going to remove the grass around them and add a circle of mulch (Pine Needles) around them to try and stop the weeds. I am not sure what I should do as far as pruning or watering this time of year though. I am in zone 6 (South Central PA around Gettysburg).
Please take a look and offer any advice you can give me. Thank you
