Ceropegia Woodii

Place your String of Hearts where it can receive plenty of bright indirect light because it will grow much faster. Small doses of direct sun are good, however too much direct sun can scorch the leaves.

One of the most common mistakes is to hang it somewhere where the light doesn't hit the top of the plant but only the strings that are cascading because it causes putrefaction.

If you hang it somewhere, make sure the whole plant is exposed to a bright light environment. This will also help the plant to grow healthier and the new propagations to root faster

In the active growth period, water your string of hearts until the water comes through the pothole, making sure that the potting mixture is moist, but allow most of the soil to dry out between waterings.

Remember that this plant does well in a bright and warm environment. Take into account that the colder and darker is the place, the less water it needs. So during winter, water very sparingly, just enough water to prevent the potting mixture from drying out completely.

Also, it's always a good idea to plant succulents in small pots because the soil dries out quicker than in bigger pots. Then, repot them when the pot feels small for them.

Since the string of hearts is from South Africa, it does well in dry environments, does the level of humidity on an average room works for it, and won't demand you any special care.

In case you need to increase the humidity for other plants, I wouldn't place this succulent next to the humidifier.

Apply a slow release fertilizer once a month during the growing season.
