Never use potting mix or soil intended for houseplants which is designed to retain water. The Variegated String of Hearts does not like to have their feet wet too long and a good draining soil helps to dry out your plants feet quickly.

This will keep your soil fast draining and well aerated.
To help aid your Variegated String of Hearts keeping their feet dry, in addition to good soil, you need a pot with good drainage. The more drainage holes the better.
