Introducing the string of watermelon, known as Senecio herreianus (now Curio herreianus), which is a popular trailing succulent native to South Africa. It belongs to the Asteraceae family and is loved for its unique foliage and trailing growth habit. It has several other common names such as Gooseberry Plant, String of Beads, String of Pearls, String of Raindrops, Curio herreanus, Senecio herreanus, and String of Tears. 

The string of watermelon is a stunning succulent with trailing stems and egg-shaped leaves, similar to a String of pearls but larger and elongated. It can grow over 2 feet long and can be found trailing from a pot or creeping along the ground. The leaves are green, lined with dark green or purple tones, resembling the rind of a watermelon, and can be deepened by bright sunlight.  

When grown as a houseplant, the string of watermelon can reach a height of about 6-8 inches and spread out in a trailing manner. It's a great choice for hanging baskets or as a trailing accent in pots. 

This plant's flowers bloom from spring to fall and are white or off-white, with small, daisy-like blooms. The plant is known for its ability to attract butterflies and bees with its sweet nectar. Its delicate petals bring a touch of elegance to any garden or landscape. 

You can propagate the string of watermelon through stem cuttings. Simply take a healthy stem cutting, remove the lower leaves, and allow the cutting to dry for a day or two. Then, place the cutting in well-draining soil and keep it slightly moist. Over time, it will develop roots and start growing into a new plant. 

Watering Needs 

Like most succulents, the string of watermelon prefers well-draining soil and doesn't like to sit in wet conditions for too long. Overwatering can cause root rot and other issues, while underwatering can cause leaves to shrivel and drop. 

Before watering, insert your finger about an inch into the soil to check if it's dry. If it feels moist, wait a few days before watering. When watering, ensure that the soil is well saturated until water drains from the bottom of the pot. This ensures that the roots get enough moisture. 

In the spring and summer, during the growing season, water your string of watermelons every 1-2 weeks. In the dormant period (fall and winter), you can reduce watering to once every 3-4 weeks. 

Remember, it's always better to underwater than overwater your string of watermelon. If in doubt, it's safer to wait a little longer between waterings. 

Light Requirement 

When grown indoors, the string of watermelon thrives in bright, indirect light. Place it near a window that receives bright, filtered sunlight for a few hours a day. Avoid exposing the leaves to direct sunlight because it can scorch them. 

For outdoors cultivation, it can handle more direct sunlight. However, it's still best to provide it with partial shade during the hottest parts of the day, especially in regions with intense sun. Morning or late afternoon sun is ideal, as it gives the plant the light it needs without the risk of burning the leaves. 

When transitioning your string of watermelon from indoor to outdoor or vice versa, it's important to acclimate it gradually to prevent shock. Start by placing it in a slightly shadier spot for a few hours a day, then gradually increase its exposure to brighter light over the course of a week or two. 

Remember, the string of watermelon can adapt to different light conditions, but it generally prefers bright, indirect light indoors and partial shade with some direct sunlight outdoors. Observing the plant's response to light and adjusting accordingly will help it thrive. 

Optimal Soil & Fertilizer 

The string of watermelon plants favors very airy, sandy soil that drains well. Planting them in ordinary soil will result in compacted roots, stunted growth, and most likely root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized succulent potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your succulent to thrive. 

The string of watermelon is a relatively low-maintenance plant when it comes to fertilizing. During the growing season in the spring, you can feed it with a balanced (5-10-5), water-soluble NPK fertilizer diluted to half strength. Apply the fertilizer once a year to provide the necessary nutrients for healthy growth. 

When applying fertilizer, make sure to water the plant thoroughly first. Then, dilute the fertilizer according to the instructions and apply it to the soil around the base of the plant. Avoid getting the fertilizer on the leaves, as it can cause burns. 

Remember, it's always better to under-fertilize than over-fertilize your string of watermelon. Too much fertilizer can lead to excessive growth and weak stems. Always follow the instructions on the fertilizer package and adjust the frequency of application based on the plant's response. 

Hardiness Zone & More 

When growing indoors, the string of watermelon prefers temperatures between 60°F and 75°F. It can tolerate slightly cooler temperatures during the winter months as long as it's not exposed to frost or freezing conditions. The string of watermelon appreciates moderate to high humidity levels. You can boost humidity by placing a tray filled with water near the plant or using a humidifier. Misting the leaves occasionally can also help provide some humidity. 

When grown outdoors, the string of watermelon thrives in hardiness zones 9 to 11, which are regions with milder climates. These zones generally have average minimum temperatures ranging from 20°F to 40°F. 

The string of watermelon succulents appreciates moderate humidity levels outdoors as well. In regions with naturally higher humidity, the plant can thrive. However, if you live in a drier climate, you can increase humidity by misting the leaves or placing a humidity tray nearby. 

Final Thoughts

Overall, the string of watermelon is a charming and unique plant that brings a touch of whimsy to any space. With its trailing stems and bead-like leaves resembling watermelons or pearls, it's a real eye-catcher. This low-maintenance succulent is perfect for hanging baskets or as a trailing accent in pots. While its small, daisy-like flowers are less significant, the focus is truly on its stunning foliage. Propagating the string of watermelon through stem cuttings is also relatively easy. It requires plenty of sunlight, well-draining soil, and regular watering to thrive. So, if you're looking for a fun and easy-to-care-for plant that adds a pop of green to your surroundings, the string of watermelon is a fantastic choice.

Pests & Common Problems of String of Watermelon

The string of watermelon is generally a pest-resistant plant. However, it can be susceptible to a few common problems, including: 

Mealybugs: These small, white, cottony insects can infest the plant and suck sap from the leaves. To control them, you can wipe them off with a cotton swab dipped in rubbing alcohol or use an insecticidal soap. 

Spider mites: These tiny pests can create fine webbing on the plant and cause yellowing or stippling of the leaves. Regularly misting the plant and keeping it in a humid environment can help prevent spider mites. If an infestation occurs, you can use insecticidal soap or neem oil to control them. 

Root rot: Overwatering or poorly draining soil can lead to root rot, causing the roots to become mushy and black. To prevent root rot, make sure the plant is in well-draining soil and water it only when the top inch of soil is dry. 

Leaf drop: Excessive watering or sudden changes in temperature can cause the string of watermelon to drop its leaves. Ensure you're providing the right amount of water and avoid placing the plant near drafts or in extreme temperature conditions. 

Lack of light: Insufficient light can lead to leggy growth and pale leaves. Place your string of watermelon in a bright spot with indirect sunlight to promote healthy growth. 

Remember, keeping an eye on your plant's health and addressing any issues promptly can help your string of watermelons thrive. If you notice any signs of pests or problems, take appropriate action to maintain its well-being.
