Ceropegia linearis subsp. woodii

String of Hearts prefers its soil to stay moist but not soggy, so it's key to ensure the soil is completely dry before you water it again. Brown, crispy edges on the leaves are a surefire sign your String of Hearts isn't getting enough water. It's important not to over water the plant, as this can damage the roots and cause root rot.

String of Hearts needs a lot of bright light, however direct sunlight should be avoided, as this can cause the plant to become scorched. A sunny windowsill is ideal, as it will give the plant enough light to thrive, while still giving it a bit of shade. If grown outside in warmer climates, it should be placed in dappled sunlight, so some parts of the plant are still in shade.

String of Hearts prefers fairly warm temperatures in the range of 60-80°F (15-27°C), but it is still tolerant of cooler temperatures in the 50-60°F (10-15°C) range. Below 50°F (10°C) or above 85°F (30°C), the plant will begin to struggle.

String of Hearts prefers a humid environment of at least 50% relative humidity, although it can tolerate lower levels of relative humidity. Regular mistings can help keep the soil from drying out and maintain the humidity in your home or greenhouse.

String of Hearts prefers a light, well-draining potting soil. A combination of peat, vermiculite, and perlite is a good choice, but any well draining potting mix should do the trick. Avoid soils or planting mixes with added fertilizers as they are unnecessary for this plant and could lead to nutrient burn.

Fertilize your String of Hearts monthly during the growing season (spring and summer). Use a balanced liquid fertilizer or a weak all-purpose fertilizer and dilute it to half strength. Fertilization is not necessary in the winter, as the plant is resting.

String of Hearts is vulnerable to scale, mealybugs, and aphids. To treat infestations, rinse the leaves and stems of the plant with lukewarm water to remove the pests and use a very mild soap solution. Afterward, apply a neem oil spray or another organic insecticide. If the problem persists, consult with your local plant care professional.

It's best to repot your String of Hearts every year or every other year. Move the plant into a new pot that's just a bit bigger than the current one, using a light, well-drained potting mix. Make sure to water deeply after repotting to help the soil and roots settle in.

String of Hearts should be pruned regularly, with dead vines removed completely. Trim back any overgrown stems to promote healthy new growth. Longer stems can be divided and propagated to grow more String of Hearts.

Mulching is not necessary for String of Hearts, and it should be avoided as it can increase the risk of root rot. If you choose to use mulch, use a layer of coarse organic matter such as shredded bark or pine needles.

String of Hearts can be propagated easily from stem cuttings. Cut a stem at least 3-4 inches long from the main plant and allow it to callous over for a day or two. Then, place the calloused cutting in a light, well-draining soil mix and keep it in a bright, warm area with slightly moist soil. With consistent care, roots should begin to develop within a few weeks.

When String of Hearts begins to grow longer and heavier, you may need to provide additional support to help the vines stay upright. You can use a trellis, stakes, plant stakes, or wire mesh depending on the size of the plant.

String of Hearts should be given a short rest period in the fall and winter. During this time, cut back on watering and fertilization, and keep the temperature lower. Once spring arrives, the plant should be given more light and water and should be brought back to its regular care routine.

String of Hearts is not toxic to pets, making it a great choice for households with small children or pets.
