String of Hearts Benefits

The plant’s delicate, heart-shaped leaves and trailing vines add a touch of elegance and beauty to any room. Its unique appearance can complement various interior designs, from bohemian to minimalist.

Like many houseplants, String of Hearts can contribute to improving indoor air quality. Plants can absorb toxins and carbon dioxide from the air, releasing oxygen in return, which can contribute to a healthier living environment.

This succulent vine is relatively easy to care for, requiring minimal watering and moderate light. Its drought-tolerant nature makes it an excellent choice for those who might not have a lot of time for plant care or are often away from home.

Its compact size and trailing growth habit make it an ideal plant for small spaces, hanging baskets, or as a decorative tabletop plant. It can add greenery to your space without taking up much room.

The plant’s trailing vines can be styled in various ways, such as allowing them to hang from shelves or ledges, or training them around a trellis or hoop for a more structured look.

Choosing a Plant

When selecting a String of Hearts plant, look for specimens with vibrant, healthy leaves and no signs of pests or diseases. It’s also wise to check the soil and roots; they should be well-established but not overly crowded in the pot.

How to Grow a String of Hearts Plant

Planting

  • Potting Mix: String of Hearts thrives in well-draining soil to prevent root rot. A mixture of potting soil with perlite or sand will ensure adequate drainage. Some gardeners prefer using a cactus or succulent mix for added drainage.
  • Container: Choose a pot with drainage holes to allow excess water to escape. Terracotta pots are a great option as they are porous, helping the soil to dry out more evenly.

Location and Light

String of hearts prefers bright, indirect light. A south or west facing window is ideal in most climates as it provides plenty of gentle sunlight. Direct hot midday sun should be avoided as it can scorch the leaves. If you don’t have a bright window, consider supplementing with a grow light.

You’ll know your string of hearts is getting adequate light if the leaves remain plump and rounded. If they start to flatten or turn reddish, it needs more light. Insufficient light can also cause sparse, leggy growth.

Watering and Soil

As a succulent, string of hearts should be watered thoroughly but infrequently. Wait until the soil is completely dry before watering again. Depending on factors like light and temperature, this can take 1-2 weeks. The thicker the leaves, the less frequent watering is needed.

In the cooler, dormant months (fall and winter), reduce watering frequency, allowing the soil to dry out more thoroughly. Overwatering is a common pitfall, so err on the side of underwatering rather than overwatering.

Well-draining soil is critical to prevent soggy roots. A cactus/succulent potting mix amended with extra perlite works well. Terracotta pots also improve drainage and help the soil dry out faster between waterings.

When watering, pour enough so it runs freely from the drainage holes. This ensures it moistens the entire root zone. Allow any excess water to drain away before returning the plant to its cache pot or decorative planter if one is used.

Humidity

While string of hearts adapts well to average home humidity, higher levels can support faster growth and healthier leaves. Place pots on a pebble tray filled with water, mist leaves occasionally, or use a humidifier during dry winter months. Take care not to overdo it though, as excess moisture invites diseases.

Temperature

String of Hearts prefers average indoor temperatures between 60-80°F (15-27°C) and does not tolerate cold drafts or temperatures below 50°F (10°C).

Fertilizer

Feed monthly during the growing season with a balanced liquid succulent fertilizer diluted to half strength. This provides nutrients for developing new foliage and vines. Go easy on fertilizer for string of hearts though, as too much can cause leggy growth. It’s generally better slightly under-fertilize than overdo it.

Do not fertilize in the dormant winter months, as the plant’s growth slows down and it requires fewer nutrients.

String of Hearts Care

Pruning and Grooming

Pruning helps maintain the plant’s shape and encourages fuller growth. Trim any dead or yellowing leaves and cut back overly long vines if desired, especially in spring or early summer. This not only keeps your plant looking tidy but also promotes new growth.

Repotting

If growth slows down or roots are growing out of the drainage holes, it is time to repot. Choose a pot that’s 1-2 inches larger in diameter than the current pot and ensure it has adequate drainage holes.

A well-draining mixture suitable for succulents or cacti is ideal. You can make your own by mixing potting soil with perlite, pumice, or sand. Place a layer of potting mix at the bottom of the new pot. This ensures that the roots will sit at the correct height.

Gently remove the String of Hearts from its current pot. You might need to tap the pot’s edges or squeeze a flexible pot to loosen the soil.

Place the plant in the center of the new pot and gently spread out the roots. Fill in around the roots with fresh potting mix, tapping the pot occasionally to settle the soil. Ensure the soil level remains the same as it was in the original pot, avoiding burying the stems too deep.

After repotting, water the plant lightly to help settle the soil around the roots and reduce transplant shock. Avoid heavy watering until new growth indicates that the plant has acclimated to its new pot.

String of Hearts Propagation

One of the best things about string of hearts is how satisfying they are to propagate! Trailing stems root easily in water or soil, allowing you to multiply your plant.

To propagate in water, cut a strand that has at least 3 sets of leaves. Remove the bottom leaves and place the cutting in a jar of water, changing the water weekly. Roots usually emerge in 2-3 weeks.

Soil propagation follows a similar method, except the cuttings are inserted in moist well-draining potting mix instead of water. Keep the soil slightly moist until new growth indicates the cutting has rooted.

As the cuttings develop roots and new growth, they can be transplanted into pots to create full trailing plants. Propagating string of hearts is an enjoyable, rewarding way to create new plants!

String of Hearts Problems and Troubleshooting

While string of hearts are not difficult plants when their basic needs are met, they can develop issues if given improper care. Here are some common problems and how to resolve them:

  • Leggy growth: Usually caused by insufficient light. Provide brighter light conditions.
  • Sparse foliage: Indicates not enough light or fertilizer. Increase both.
  • Red or brown crispy leaves: Signs of too much sun or underwatering. Adjust conditions accordingly.
  • Rotting stems: Overwatering or poorly draining soil. Allow soil to dry out completely before watering again. Repot in a grittier soil.
  • Pale leaves: Can indicate overwatering or fertilizer deficiency. Ease up on watering frequency and feed with fertilizer.
  • Failure to thrive: Generally caused by unsuitable lighting and cultural conditions. Review and adjust care regimen.
  • Pests: While relatively pest-resistant, String of Hearts can occasionally be affected by common houseplant pests such as spider mites or mealybugs. Inspect your plant regularly and treat any infestations promptly with insecticidal soap or neem oil.

With attentive care and suitable growing conditions, many string of hearts live for years and grow into spectacular flowing specimens trailing several feet long.

Tips for Healthy String of Hearts
