Caring for string of hearts is very easy. For healthy and proper growth the right amount of light, temperature, water, and fertilizers are required.
This plant needs plenty of direct light (3–4 hrs/day).
For indoor, it can be placed near a sunny window and for outdoors, partial shading is necessary.
Side effects of low light
Low light will stunt stem elongation and cause large spaces between leaves. It also turns pale, sparse to plant, and causes a purplish hue or loss of the coloration or wilting of leaves.
Side effect prolonged sunlight
On the other hand, direct exposure to the sun for a long time will scorch its leaves. Thus this plant needs small doses of direct sun.
Irrigate only when the top two-thirds of the soil becomes dry. Water thoroughly during spring to early fall. Excess water or over-watering causes rotting of tubers and roots. It may cause yellow-brown spots and loss of the leaves.
The string of heart plants needs well-draining, light, nutritious, breathable soil. Best growth is obtained in equal parts of soil and perlite or sand.
Only fertilize the mature plants. Half-diluted water-soluble fertilizer gives good results during the active growing season. Do not fertilize the plant during dormant or winter seasons.
This plant does not require to be repotted often as they perform best in crowded pots. Generally repotting is done in the spring before they start growing again. Moreover, this plant does not need a very deep pot because it has very shallow roots so use a shallow container.
Pruning is necessary to control the length of the vines and keep them looking attractive.
7. Temperature and humidity
Best grown in 15-23 ºC (60-75 °F) for outdoor and 25–30ºC (below 60°F) for indoors with 40-50% humidity.
The string of Hearts Propagation
Plants are easily grown from seed, stem cuttings, or tubers that grow along the stems.
Use equal parts of a soil-based potting mixture, coarse sand, and perlite as a growing medium. Make sure drainage is good. The best time to propagate should be done during the spring (i.e. the growing season).
Propagation by tuber and seeds
Plant seed and tuber take 1-2 weeks for germination when covered in a thin layer of sand. Proper development, it requires around 8 weeks. The best time for the propagation is in spring.
Propagation by stem cutting
The string of heart plants can be easily propagated using stem cuttings with at least some internodes. Place them in a container with water or soil for a few days to weeks for the roots to grow out.

Moreover, feeding the plant with half diluted water-soluble fertilizer in spring is helpful for its growth.
How fast does the string of hearts grow?
