About String of Pearls

String of Pearls (Senecio rowleyanus) is native to the arid regions of southwestern Africa, which explains its preference for minimal water and bright, indirect sunlight.

Each “pearl” on its long, trailing vines serves as a tiny water storage unit, allowing the plant to withstand drier conditions.

This succulent is perfect for hanging baskets, where its vines can dangle beautifully, or on high shelves where it can really show off.

If you care for your string of pearls plant just right, it may even produce small, white flowers with a light, cinnamon-like fragrance!

How To Grow & Care For A String Of Pearls Plant

Here are some essential tips to grow and care for string of pearls plants:

1. Light Requirements

String of Pearls plants love bright, indirect sunlight and will grow best in a sunny room with filtered light.

If you can, place it near a window where it can soak up the light without being exposed to direct sun, which can cause burns.

If your home doesn’t get much natural light, consider using a grow light to give your plant a boost.

Regularly rotate the plant to help it grow evenly and prevent it from stretching toward one side.

2. Water

String of Pearls plants need a “soak and dry” approach—give it a good soak, then let the soil dry out completely before watering again.

Watering every 1-2 weeks is usually enough, but adjust based on the season; it needs less water in winter.

Overwatering is a common mistake, so be mindful of how much water your plant is getting.

Use room-temperature water and ensure excess water drains out to prevent root rot.

3. Soil

String of Pearls plants do best in a well-draining soil mix, which prevents water from pooling around the roots.

Choose a cactus or succulent potting mix for best results, and you can add some perlite or sand to make it even more free-draining.

Standard potting soil holds too much moisture and could cause root issues for this plant.

Proper soil is key to keeping your String of Pearls healthy and thriving.

4. Pot Selection

The right pot can make a big difference for your String of Pearls, so choose one with good drainage.

A pot with several drainage holes at the bottom will help prevent water from lingering, which could harm your plant.

Terra-cotta pots are a great option since they absorb some moisture, helping to keep the roots from getting too wet.

A shallow pot works well for String of Pearls because of its shallow root system.

5. Temperature

String of Pearls plants prefer warmer temperatures during the day, ideally between 70°F and 80°F (21°C to 27°C).

It can handle cooler temperatures at night, but make sure it’s protected from frost or extreme cold.

Try to keep your plant away from drafty windows, heating vents, or air conditioners, as sudden temperature changes can be stressful.

In a steady environment, String of Pearls will grow strong and healthy.

6. Humidity

String of Pearls plants are happiest in low to moderate humidity, which makes it a great match for most indoor spaces.

It’s best to keep it away from high-humidity rooms like the bathroom, where moisture can build up and impact the plant.

Standard household humidity is usually just fine, so you won’t need a humidifier for this one.

If you live in a humid area, ensure good air circulation around the plant to avoid excess moisture.

7. Fertilizing

During the growing season, String of Pearls will benefit from a little extra nutrition.

Use a diluted, balanced fertilizer for succulents every 4-6 weeks from spring through early fall.

Avoid fertilizing during the winter when the plant naturally slows down, as it won’t need the extra nutrients.

Be careful not to over-fertilize, as too much can harm the plant’s roots.

8. Pruning and Propagating

Pruning helps your String of Pearls look fuller and encourages healthy new growth.

Trim back any long or scraggly vines using clean scissors, and don’t throw those cuttings away—they’re perfect for propagating!

To propagate, simply place the cuttings on moist soil, pressing down gently so the nodes touch the surface.

Roots will develop within a few weeks, and soon you’ll have new baby plants to enjoy or share!

9. Pest Control

String of Pearls plants are generally resistant to pests, but it can occasionally attract aphids, spider mites, or mealybugs.

Check your plant regularly, and if you spot any pests, treat them right away with insecticidal soap or neem oil.

Good airflow around the plant can help prevent infestations, as pests thrive in stagnant environments.

Regular checks will keep your String of Pearls looking healthy and pest-free.

10. Repotting

Repot your String of Pearls every 1-2 years to refresh the soil and give it a bit more space to grow.

Choose a pot that’s only slightly larger than the current one, as a too-large pot can retain excess moisture.

Be gentle when handling the roots during repotting, as they’re delicate and can break easily.

Repotting helps rejuvenate the plant and keeps it thriving for years to come.

11. Watch for Signs of Distress

Keep an eye on your plant for any signs of stress, like yellowing or shriveled leaves.

Yellow leaves may mean it’s getting too much water, while shriveled pearls are a sign it may need more.

Regularly checking your plant helps you catch issues early so you can make adjustments to your care routine.

By responding quickly to these signs, you can keep your String of Pearls healthy and happy.

12. Support for Trailing Growth

String of Pearls plants are a natural trailer, so give it space to grow and show off its beautiful vines.

Hanging baskets are ideal, or you can place it on a high shelf to let the vines cascade.

Providing support allows the plant to grow freely, and it looks lovely as it fills out its space.

Mistakes To Avoid When Growing String of Pearls

Now that we’ve determined the best ways to grow and care for a healthy string of pearls plant, let’s take a look at what not to do:

1. Overwatering

String of Pearls plants are sensitive to overwatering, which is one of the most common mistakes people make.

Remember, this plant is a succulent, and its roots prefer dry soil between waterings.

Always let the soil dry out completely before adding more water, especially in cooler seasons.

A good rule of thumb is to err on the side of underwatering rather than overwatering.

2. Using the Wrong Soil

Regular potting soil can hold too much moisture and lead to root rot.

Always use a well-draining cactus or succulent mix to give your plant the best chance to thrive.

Adding perlite or coarse sand helps the soil stay light and airy, which String of Pearls loves.

The right soil can make a huge difference in your plant’s health and happiness.

3. Inadequate Light

String of Pearls plants need bright, indirect light to grow well, so a dim room won’t cut it.

Without enough light, it may start to look stretched out and leggy.

Make sure your plant has plenty of light, and consider a grow light if natural sunlight is limited.

With the right lighting, your String of Pearls will stay lush and full.

4. No Drainage in Pot

A pot without drainage can trap water, which is a big no-no for String of Pearls.

Drainage holes let excess water escape, preventing the roots from sitting in soggy soil.

If your pot doesn’t have drainage, it’s worth repotting into one that does.

This simple change can save your plant from potential root rot.

5. Too Much Direct Sunlight

Direct sunlight can scorch the delicate pearls, causing browning and sunburn.

Place your plant in bright, indirect light instead, or use sheer curtains to diffuse harsh sunlight.

Too much sun exposure can damage your String of Pearls, so a bit of filtered light is ideal.

A perfect spot is one that gets lots of light without harsh rays.

6. High Humidity

String of Pearls plants prefer lower humidity levels, so keep it away from overly damp areas.

Humidity can cause fungal growth and affect the plant’s overall health.

If you live in a humid environment, ensure good air circulation to keep the plant dry.

A low-humidity space is ideal for this succulent to thrive.

7. Over-Fertilizing

Over-fertilizing can damage the roots and make the plant susceptible to nutrient burn.

A diluted succulent fertilizer every 4-6 weeks in spring and summer is plenty.

Avoid fertilizing during the winter when growth naturally slows.

Less is more when it comes to feeding String of Pearls!

8. Moving the Plant Too Frequently

String of Pearls plants like stability, so moving it around too much can cause stress.

Find a well-lit spot and try to keep it there, avoiding unnecessary relocations.

Frequent moves can disrupt its light and temperature needs, impacting growth.

A stable environment helps this succulent feel right at home.

9. Underwatering

Though it’s drought-tolerant, String of Pearls still needs occasional water to thrive.

Signs of underwatering include shriveled pearls, indicating the plant is using up its water reserves.

Try to establish a regular watering schedule based on the plant’s needs and environment.

With a little attention, you’ll find the balance that keeps your plant happy.

10. Neglecting to Prune

Without pruning, String of Pearls can start to look sparse and less vibrant over time.

Trim any overly long or scraggly vines to encourage fuller, bushier growth.

Pruning also gives you cuttings to propagate new plants, which is a fun bonus!

Regular upkeep keeps your plant looking its best.

11. Ignoring Pest Infestations

Check your String of Pearls regularly for any signs of pests, like aphids or mealybugs.

Pests are rare but can appear, especially in dry, dusty areas.

Early detection is key, so treat any infestations with neem oil or insecticidal soap.

Routine checks help keep your plant healthy and pest-free.

12. Not Checking for Signs of Distress

Regularly monitor your plant for changes in color, texture, or growth pattern.

If you see yellowing, shriveling, or slowed growth, it’s a signal to adjust your care.

Quick action can help prevent bigger issues and keep your plant healthy.

A little attention goes a long way in caring for your String of Pearls.

Conclusion

String of Pearls plant care can be both easy and rewarding with the right approach.

By following these tips and avoiding common mistakes, you’ll help your plant grow into a lush, trailing beauty.

It’s all about finding the right balance of light, water, and care to keep your plant thriving.

With just a bit of love and attention, your String of Pearls will flourish and bring a lovely touch of greenery to your space!
