where do i locate the bud union for planting roses in marshfield mass 02050? I have roses i have already planted 3-7 yrs ago and i have exposed the bud all these years. I have provided much mulch/leaf for winter care overmounding it on the plant after the 1st freeze and then i take 5 inches of previously newspaper and I build a vertical block of these around the roses and have not lost any. I just read i should relocate this to 2" below the soil. Is this true? Also, can I get suggestions for replanting a climber best time cut down b4 etc I planted climbing edens and one has now turned red. beautiful but wrong color and i would like to relocate also any suggestions for roses that can do well with a little shade Thanks
