Gardening Term: Removing Suckers from a Rose Bush

Definition:

Suckers are shoots that emerge from the rootstock of a rose bush, usually below the graft union. They are genetically different from the desired rose variety and can negatively impact the overall health and vigor of the plant. Removing suckers is the process of cutting or pulling out these unwanted shoots to maintain the integrity and beauty of the rose bush.

Why is it necessary to remove suckers from a rose bush?

Suckers can be detrimental to the growth and development of a rose bush for several reasons:

Drain on Resources: Suckers compete with the main rose plant for essential nutrients, water, and sunlight. This competition can weaken the overall health of the rose bush, leading to stunted growth, reduced flower production, and increased susceptibility to diseases and pests.

Rootstock Dominance: Suckers originate from the rootstock, which is often a wild or less desirable rose variety. If left unchecked, suckers can overtake the desired rose variety, resulting in the loss of its unique characteristics, such as flower color, fragrance, or growth habit.

Weak Growth: Suckers tend to grow rapidly but with weak stems and foliage. Their growth can disrupt the natural shape and form of the rose bush, making it appear untidy and unattractive.

Disease and Pest Vulnerability: Suckers are more susceptible to diseases and pests compared to the cultivated rose variety. Their presence can serve as an entry point for pathogens and insects, potentially spreading infections to the entire plant.

To remove suckers from a rose bush:

Identify the suckers by their location below the graft union, which is usually a swollen area near the base of the plant.

Using sharp pruning shears or a clean, sharp knife, cut the suckers as close to the rootstock as possible. Avoid tearing or damaging the main rose plant.

If the suckers are small and tender, they can also be pulled out by hand. Ensure that the entire sucker, including its roots, is removed to prevent regrowth.

Dispose of the removed suckers properly, as they may still have the potential to grow if left on the ground.
