How To Grow Plants From Strawberry Runners

Sharing is caring!

Strawberry plants are prolific breeders, known not just for their delicious fruit but also for their ability to propagate through runners. These runners, or stolons, are long, horizontal stems that grow outward from the main plant.

As gardeners, taking advantage of these runners can be an excellent way to expand your strawberry patch while maintaining the genetic consistency and vigor of your existing plants. This guide will walk you through the process of growing new strawberry plants from runners.

Identify Healthy Strawberry Runners

The first step in growing new plants from runners is to identify which runners to use. Not all runners are created equal; the best candidates for replanting are healthy, robust, and come from vigorously growing, disease-free parent plants.

Look for runners that have already started developing small leaves and maybe even roots. These signs indicate that the runner is ready to support a new plant. Avoid any runners that look wilted, discolored, or show signs of disease or pest damage.

Prepare Your Planting Area

Strawberries thrive in well-drained, loamy soil with a pH between 5.5 and 6.8. To prepare your planting area, start by testing the soil pH and adjust it if necessary using lime (to increase pH) or sulfur (to decrease pH).

Incorporate organic matter like compost or well-rotted manure to enrich the soil and improve its structure.

Choose a location that receives full sun for at least six to eight hours per day. Strawberries also prefer a slightly elevated or sloped site for better water drainage.

Once you have selected the ideal spot, clear the area of weeds and work the soil until it is loose and friable, ready for planting.

Detach Runners Properly

When your selected runners have developed a few small leaves and roots, it’s time to detach them from the mother plant.

This is best done in late summer to early fall. Carefully follow the runner to its tip where you’ll find the young plantlet.

Use a sharp pair of scissors or shears to cut the runner, leaving a few inches of stem on either side of the plantlet. Make sure not to disturb the roots that have started to form.

Plant the Runners

Plant the detached runners promptly to avoid drying out. Dig a small hole for each plantlet, ensuring it’s deep enough to accommodate the roots comfortably.

Position the plantlet so that the crown (where the leaves emerge) is level with the soil surface. Backfill the hole with soil, gently firming it down to eliminate air pockets.

Space the plantlets about 12 inches apart to allow room for growth and air circulation, which helps prevent fungal diseases.

Ensure Adequate Watering

Watering is crucial in the initial stages after planting. The soil should be kept evenly moist, but not waterlogged.

Water the newly planted runners generously right after planting to settle the soil around the roots and eliminate any remaining air gaps.

Continue to provide water whenever the top inch of soil feels dry to the touch. Consistent moisture is especially important in the weeks after planting, as it helps the new plants establish a strong root system.

Control Weeds and Use Mulch

After planting your strawberry runners, one of the next crucial steps is to control weeds in the area. Weeds compete with young plants for nutrients, water, and light, hindering their growth.

Regularly hoeing around the plants can help prevent weeds from taking hold. However, be gentle around the shallow roots of your strawberry plants to avoid damaging them.

Using mulch is highly beneficial for strawberry plants. Mulch helps retain soil moisture, keeps weed growth under control, and can also help regulate soil temperature.

Straw is a popular choice as it is light and won’t compact over the roots. Lay a generous layer of straw around the plants, ensuring not to cover the crowns to prevent rot.

Fertilize at the Right Time

Strawberries benefit from regular fertilization, but it’s important to get the timing right to encourage the best growth and fruit production.

About four to six weeks after planting, apply a balanced fertilizer, such as 10-10-10, around the base of the plants.

Avoid getting fertilizer on the leaves to prevent burn. A second application of a potassium-rich fertilizer can be beneficial when the plants begin to flower, promoting better fruit quality and yield.

Protect New Plants From Pests and Diseases

Strawberries are susceptible to several pests and diseases which can be detrimental to both plant health and fruit production.

Common pests include slugs, aphids, and spider mites, while fungal diseases such as powdery mildew and leaf spot are also prevalent.

Regularly inspect your plants for signs of infestation or disease, such as discolored leaves, sticky residues, or powdery coatings.

To combat these issues, maintain good air circulation by spacing plants properly and using mulch to reduce humidity around the plants. If pests or diseases appear, use appropriate organic or chemical treatments as necessary.

For organic control, neem oil and diatomaceous earth are effective against a variety of pests and mild diseases.

Encourage Runner Development

As your strawberry plants mature, they will naturally start to produce their own runners. To encourage strong, fruitful plants, you may want to manage these runners.

Allowing all runners to grow can lead to overcrowding and reduced fruit size. Select two to three strong runners per plant to root and remove the rest.

This channels more energy into fruit production and maintaining a manageable number of new plants.

Prepare for Winter

In colder climates, winter protection is vital for ensuring that your strawberry plants survive the freezing temperatures.

After the first frost, mulch your strawberry beds with straw or pine needles to protect the roots. This insulation prevents freeze-thaw cycles that can heave and damage plants.

Remove the mulch in early spring once the threat of frost has passed, but before the plants start actively growing.

Growing plants from strawberry runners is a rewarding and economical way to expand your strawberry patch.

By following these detailed steps, from selecting and planting runners to caring for young plants through their first season, you ensure a strong foundation for a healthy, productive garden.

Remember, the key to success lies in regular care and attention, so keep nurturing your plants, and you’ll enjoy abundant harvests for years to come.

By combining the guidance from both parts of this guide, you should have a comprehensive roadmap for propagating and maintaining strawberry plants effectively, ensuring a lush and fruitful garden.
