Reduces Sucker Growth from Rootstock
On grafted roses, unwanted suckers from the rootstock can sap vigor from the flowering variety. Pruning removes these intruders, channeling energy back into the blooming canes above. I always inspect for baby shoots emerging below the graft union—catching them early is key!
Eliminating suckers ensures that every nutrient packet goes toward producing spectacular flowers on the grafted stems you chose, rather than fueling an anonymous interloper. More juice for the blooms you love!
