How can I effectively control sucker growth on rose bushes?
Root suckers, or growth from the base of plants, are a notorious problem with rose bushes as well as some other plants such as lilacs and sumacs. These shoots arise from roots, often at a distance from the plants, as the roots grow outwards. Or, they may arise from the base of plants from below the graft union if plants are grafted or budded (as are most roses and many lilacs). Often this suckering is unwanted, and in the case of grafted plants, will produce a plant different from the one purchased. Control suckers by cutting them as close to the ground or root stock as possible. Planting deeper than normal, such as with the graft union 4 to 6 inches below ground, also may help to prevent suckering. There are some products available on the market that inhibit sucker growth. If applied to suckers shorter than 6″ long they will prevent their growth for up to 3 months.
