Turtle Vine Care
Here are the main care requirements for growing beginner-friendly turtle vines:
- Pot in a well-draining soil or potting medium.
- Position in part shade or bright but indirect light.
- Water before the soil fully dries to maintain the healthiest foliage.
- Feed monthly during the growing season.

Light
Turtle vines, which grow in shady forests in their subtropical and tropical native habitats, don’t do well in full sun.
Keep these plants in partial shade outdoors or bright but indirect light indoors for the healthiest growth. They may appreciate full shade in the hottest regions, but if you spot leggy growth or fading foliage coloring, move them into a brighter spot.
Soil
Turtle vines aren’t too fussy about soil, provided it is well-draining. When growing this species indoors, select a commercial succulent mix or add something like perlite to enhance drainage.
While these plants can handle poor soils, they do best in fertile, humusy soil amended with organic matter, such as compost.
Water
While turtle vines, with their fleshy, water-storing foliage, can handle an element of neglect and an irregular watering schedule, they prefer to be kept evenly moist.
Ideally, you should deeply water when the soil is around 50% dry and avoid letting the soil dry out completely. Always drain away any excess standing water—these plants are prone to root rot if the soil is soggy.
Temperature and Humidity
Turtle vines are heat and humidity lovers, best reserved for growing as annuals or houseplants if your region has winter temperatures that drop below 40°F for any length of time.
Indoors, they appreciate temperatures of around 65°F to 85°F. If the humidity levels in your home are low, the plants will appreciate sitting on a pebble tray filled with water for a beneficial moisture boost.
Fertilizer
While turtle vines can tolerate poor soils, they produce the most vigorous growth with extra nourishment.
Amending soil with organic matter is often sufficient when growing turtle vines outdoors. Indoors, apply a monthly application of a general-purpose fertilizer diluted to half-strength from spring through fall.
Types of Turtle Vine
There are several turtle vine cultivars with differing leaf colors to look out for. These include:
- Callisia repens ‘Bianca’: Features mini variegated pink and green foliage.
- Callisia repens ‘Gold’: It stands out for its bright yellow-green variegated leaves.
- Callisia repens ‘Pink Panther’: The small foliage features shades of green, pink, and white stripes. The leaf underside is a red-purple shade.
Pruning
Turtle vines have a trailing growth habit but tend to be compact and small. However, occasional light pruning helps to maintain a bushy form rather than a sprawling and leggy one. Pinch the stems back between two leaves to tidy things up.
Propagating Turtle Vines
It’s easy to add new turtle vines to your collection by propagating from stem cuttings. To do this, follow the steps below at any time, but ideally in the spring or fall.
- Use sterile pruning shears or scissors to take a 3 to 4-inch cutting with at least four sets of leaves from a healthy stem. Taking several cuttings increases the chance of success and helps produce a dense covering.
- Remove the leaves from the bottom node on the stem.
- Apply rooting hormone to the base of the cutting (this is an optional step, but it can help the cutting establish).
- Pot the cutting in a well-draining medium, ensuring the node at the base is fully covered.
- Place the cutting in bright but indirect light and keep the soil evenly moist but not soggy.
- Wait for signs of new leaf growth, as this indicates the cutting has taken root successfully. At this point, you can transfer the cutting to its permanent pot or outdoor location.
Common Pests and Plant Diseases
Turtle vines aren’t bothered by many serious pests or diseases. However, spider mites can be a problem, especially when conditions are hot and dry. Using a gentle water spray, you can get rid of spider mites before infestations get out of control.
Alternatively, apply an insecticidal soap or an organic neem oil spray. Rabbits are also fans of this fleshy ground cover, so you may want to avoid planting it if they are regular visitors to your yard.
Common Problems with Turtle Vines
Turtle vines are forgiving and easy-to-grow houseplants for beginners. But if you don’t offer them the conditions they thrive in, problems can arise. Below are some of the early warning signs that you need to make adjustments.
Excess Leaf Drop
Turtle vines don’t need watering too often, but if you let the soil fully dry out regularly or for too long, they can prematurely shed their leaves.
While a little old leaf drop in houseplants is natural, when new inner leaves fall off, it can be a sign that you need to offer more moisture.
Brown Leaves
Sometimes your turtle vine plant leaves can turn brown. This is often because too much intense, direct sun is scorching them. Another reason for this type of discoloration is if you overhead water and the leaves stay wet for too long.
Leggy Growth
Too much sun is a common problem, but sometimes, too little sun can cause issues for your turtle vine. If it is overly shady, it will often stretch out to seek the available sun, and the stems can become leggy and weak.
FAQ
-
When ingested, turtle vines are mildly toxic to people and plants and may irritate the skin, so it’s best to keep them out of reach of curious kids, kitties, and canines.
-
Turtle vines are most commonly grown as houseplants. They can also be grown outdoors, but if your region doesn’t experience warm weather year-round, they will only survive as annuals. You can grow these plants as perennials in your yard in USDA hardiness zones 9 to 11.
-
The fast-growing and densely branched turtle vine is listed as invasive in South Africa, China, and Cuba. Turtle vine isn’t listed as invasive in North America, but be aware that it can smother weaker species when grown as a ground cover in areas with optimal conditions.
