Propagating Plants From Runners

Some plants naturally produce horizontal stems called runners or stolons that form new plantlets away from the parent. These plantlets can often be rooted and separated to create new plants with very little disturbance.

Understand What a Runner Is

A runner is a horizontal stem that extends from the parent plant and may form new roots and shoots at nodes.

Common Runner-Producing Plants

Strawberries are a familiar example, but other species also spread through stolons or similar structures.

Choose Healthy Parent Plants

Use runners from vigorous plants without obvious disease, severe nutrient stress, or heavy pest pressure.

Let the Runner Develop Naturally

Young plantlets usually become easier to propagate after they produce several leaves and begin forming roots.

Identify the Plantlet

A plantlet develops where the runner forms a node with leaves and potential root tissue.

Choose Strong Plantlets

Larger plantlets with healthy leaves usually establish faster than tiny newly formed ones.

Use the First Plantlet When Quality Matters

In many runner-producing plants, the plantlet closest to the parent may be stronger because it formed earlier.

Root the Plantlet While Still Attached

Keeping the runner connected allows the developing plantlet to continue receiving support from the parent.

Pin the Plantlet to Soil

Use a small wire, clip, stone, or similar anchor to keep the rooting point in contact with moist soil.

Use Small Pots for Easy Transplanting

A pot placed beside the parent plant can allow the plantlet to root without later digging.

Use Suitable Potting Mix

The medium should hold moisture while still draining well enough to provide oxygen to developing roots.

Keep the Crown Above the Soil

Do not bury the entire plantlet crown deeply, because excessive moisture around the growing point can encourage rot.

Maintain Even Moisture

Young roots dry quickly, so the rooting area should not be allowed to become completely dry.

Avoid Saturated Soil

Waterlogged conditions can rot new roots and crown tissue.

Protect From Extreme Heat

Newly rooting plantlets can wilt during hot dry weather.

Use Temporary Shade if Needed

Light protection during severe heat can reduce stress while roots develop.

Do Not Cut the Runner Too Soon

The connection to the parent provides a useful safety net while the plantlet is still establishing roots.

Check Root Development Gently

A rooted plantlet should begin resisting light movement and remain stable in the soil.

Look for New Growth

Fresh leaves are another sign that the new plant is functioning independently.

Separate After Establishment

Once the plantlet has a useful root system, cut the runner between it and the parent plant.

Use Clean Scissors or Pruners

A clean cut reduces tearing and unnecessary damage.

Leave Some Runner Stem if Helpful

A short section can make handling easier, though excessive dead stem can be trimmed later.

Water After Separation

Freshly independent plantlets may need closer moisture monitoring for several days.

Transplant Carefully

Preserve as much of the new root system as possible if moving the plantlet.

Plant at the Correct Depth

Keep crowns and growing points at the depth appropriate for the species.

Avoid Heavy Fertilizer Immediately

Young roots can be sensitive to concentrated fertilizer salts.

Remove Weak or Diseased Plantlets

Propagation material showing rot, discoloration, or serious pest injury should be discarded.

Limit Excessive Runner Production if Needed

A parent plant producing too many runners may divert energy away from fruiting or crown growth.

Choose Whether You Want Fruit or Propagation

For strawberries, gardeners may remove some runners when fruit production is the main goal.

Use Runners to Renew Old Plantings

Healthy new plantlets can replace older plants as productivity declines.

Maintain Variety Identity

Runner plantlets are clones of the parent, making them useful for preserving a known cultivar.

Label New Plants

Mark varieties when several cultivars are being propagated near each other.

Record Which Plants Produce the Best Runners

Notes can help identify vigorous parent plants for future propagation.

Practical Takeaway

Runner propagation is easiest when plantlets are allowed to root while still attached to the parent. Maintain moisture, wait for a functional root system, then separate and transplant gently.
