Should I just pull the suckers off by hand?

It is better to cut them cleanly with pruners. Pulling can tear the bark of the main root, which creates a wound that may invite disease or cause even more suckers to grow.

Will cutting the suckers kill my plant?

No, removing suckers actually helps the plant by redirecting energy back into the main stem and canopy.

Why do my trees keep producing suckers?

Some plants are genetically programmed to spread this way, but often it is a reaction to stress or damage to the roots. Check for soil compaction or accidental damage from garden tools.

Root Suckering

Symptoms by part

Roots

Small, leafy shoots emerging from the soil surface at a distance from the main trunk or base of the plant.

Causes

Damage to the root system from digging or lawn mowers
Stress caused by drought or improper watering
Natural growth habit of specific species that spread via underground runners
Heavy pruning of the main plant that triggers a survival response

Could be confused with

Seedling germination · Seedlings will have a single taproot and can be easily pulled from the soil, whereas suckers are firmly attached to a thick, woody underground root.
Rhizomatous weeds · Weeds like bindweed have thin, white, stringy roots that are distinct from the woody, thick root structure of a tree or shrub sucker.

Treatment

Identify the point where the sucker emerges from the main root system.
Use clean, sharp pruners to cut the sucker as close to the parent root as possible without damaging the main root itself.
Dig down slightly to expose the attachment point if the sucker is coming from below the soil line.
Remove the entire sucker cleanly to prevent dormant buds from sprouting again.

Without chemicals

Hand pull small, soft suckers when they first appear.
Use a sharp spade to sever the connection between the sucker and the main root.
Apply a thick layer of mulch around the base of the plant to discourage new shoots from breaking the surface.

Preventing it

Avoid deep cultivation or digging near the root zone of susceptible plants.
Maintain consistent moisture levels to reduce plant stress.
Install deep root barriers if you are planting species known for aggressive suckering.

Season

The warm growing season.

Spread risk

Moderate

Severity

Moderate

When to act

Act as soon as you notice a sucker to prevent it from establishing a strong root system. If the suckering is extensive and threatens the structural integrity of a large tree, consult a professional tree surgeon.
