The Dolphin Plant (Senecio peregrinus or Curio peregrinus) is a popular succulent known for its distinctive leaves, which resemble miniature dolphins. This hybrid, a cross between Senecio rowleyanus (String of Pearls) and Senecio articulatus (Hot Dog Cactus), produces trailing vines that can reach up to three feet. Its cascading growth makes it ideal for hanging baskets or elevated shelves.
Dolphin Plant Care Essentials
Light Needs
Dolphin Plants thrive in bright, indirect sunlight. An ideal spot is near a south-facing window, providing filtered light for several hours. An east-facing window also works, offering morning light. Avoid direct, intense sunlight, which can scorch leaves. Too much direct sunlight can also lead to yellowing leaves or brown, scorched patches. If natural light is limited, especially in winter, supplemental LED grow lights can support healthy growth. Insufficient light causes leggy growth, with elongated stems and widely spaced leaves, losing the dolphin shape. Maintaining bright, indirect light is key for the plant’s vibrant color and compact form.
Watering Practices
Proper watering is essential for Dolphin Plants, using the “soak and dry” method. Water thoroughly until it drains from the pot, then allow the soil to dry completely before the next watering. This prevents root rot. During the active growing season (spring to early fall), water about once a week or every two to three weeks, depending on conditions. Reduce watering significantly in winter dormancy, perhaps to once a month. Always check soil moisture by inserting a finger about an inch into the soil; water if dry. Overwatering causes mushy, yellow leaves, while underwatering leads to dull, shriveled leaves.
Soil Requirements
Dolphin Plants need a well-draining, porous soil mix to prevent waterlogging. A commercial cactus or succulent mix works well. Alternatively, create a blend of two parts potting soil, one part perlite or pumice, and one part coarse sand. These additives enhance drainage and aeration, allowing roots to breathe. Avoid heavy, clay-like soils that retain too much moisture. Ensure the pot has adequate drainage holes.
Temperature and Humidity
Dolphin Plants thrive in average room temperatures, between 60°F and 80°F (15°C and 27°C). They can tolerate cooler temperatures, down to 40°F (4°C) during winter dormancy, but are not frost-tolerant, requiring protection if temperatures drop below freezing. The plant prefers moderate humidity and benefits from good air circulation, which helps prevent fungal issues. Avoid placing them near direct heat sources or cold drafts, as these can stress the plant.
Fertilizing
Dolphin Plants have low fertilizer needs; over-fertilizing can negatively affect their shape. Fertilize during the active growing season (spring and summer). Apply a balanced, water-soluble liquid fertilizer, diluted to half strength, once a month or every few months. Fertilizing in early spring can stimulate growth and blooming. Water the plant before applying fertilizer and avoid getting it on leaves or stems to prevent burns. Reduce or stop fertilizing during fall and winter dormancy.
Propagating Dolphin Plants
Propagating Dolphin Plants is simple, primarily using stem cuttings. The best time is during spring and summer when the plant is actively growing. Select a healthy stem and take a 4-5 inch cutting with at least two to three nodes, which are the points where new roots will develop. Remove leaves from the bottom inch or two to expose the stem and prevent rot. Allow the cut end to callus for two to three days; this prevents rot when planted.
Once callused, place the cutting into a well-draining succulent potting mix. Keep the soil lightly moist until roots form, typically in a few weeks. Rooting hormone can be used, but it is not always necessary. Some gardeners also find success rooting cuttings in water before transferring them to soil.
Repotting Your Dolphin Plant
Repotting Dolphin Plants is not frequent, as they tolerate being slightly root-bound. However, repot every few years to refresh the potting medium and provide more space. The ideal time is spring or summer, during active growth. Signs for repotting include roots emerging from drainage holes, slowed growth, or degraded soil. Choose a new pot only one size larger with drainage holes; terracotta pots are often preferred as they help absorb excess moisture.
Gently remove the plant, loosen circling roots, and trim damaged sections. Place a layer of fresh, well-draining succulent mix in the new pot, position the plant at the same depth as before, and fill with more soil, lightly tamping it down to remove air pockets. Water thoroughly after repotting and avoid fertilizing for about a month.
Troubleshooting Common Dolphin Plant Problems
Shriveled or Wrinkled Dolphins
Shriveled or wrinkled leaves usually indicate improper watering, most often underwatering. The succulent leaves store water, and low reserves cause them to pucker or deflate. Less commonly, shriveling can result from excessive heat or direct sunlight, leading to rapid water loss. To remedy, adjust your watering schedule to thoroughly water when the soil dries. If heat or light is the issue, move the plant to a spot with bright, indirect light and better air circulation.
Yellowing Leaves
Yellowing leaves often indicate overwatering. Prolonged wet soil suffocates roots, causing rot, yellowing, and mushy stems. Insufficient light also contributes to yellowing, as the plant struggles to photosynthesize. Less often, nutrient deficiencies or natural aging cause yellowing. To address this, assess watering habits and allow soil to dry completely. Ensure adequate bright, indirect light, and consider diluted fertilizer if a nutrient deficiency is suspected during the growing season.
Leggy Growth
Leggy growth, characterized by long, stretched stems with sparse leaves, indicates insufficient light. The plant stretches towards a light source, causing weak stems and loss of compact form. To correct this, move the plant to a location with more bright, indirect light, like a south-facing window. Rotate the plant periodically for even light exposure. Pruning leggy stems above a leaf node encourages bushier growth, and these cuttings can be used for propagation.
Pests
Dolphin Plants can attract common houseplant pests like mealybugs and spider mites. Mealybugs appear as small, white, cottony masses on stems and leaf undersides. Spider mites create fine webbing and can cause stippling or yellowing. Regular inspection, especially of leaf undersides, aids early detection. For minor infestations, manually remove pests with a cotton swab dipped in rubbing alcohol. For widespread issues, apply organic pest control like insecticidal soap or neem oil, following instructions. Good air circulation also deters pests.
