Start with at least five or six healthy stalks. Not all of them may root, so this ensures you get enough rooted stalks to start a new plant off quickly.
Getting rid of the dead foliage just keeps things neater, as they’ll eventually fall off and turn slimy anyway.
Put the stalks in a jar or vase and fill with a few inches of water. Place the jar in a sunny location like a south-facing windowsill and then… just wait.
Wait until the roots are at least 3 inches long and the stalks have begun to divide (via offshoot stalks) before you plant them.
I recommend a high-quality potting soil (you can use store-bought or homemade potting soil) amended with compost, worm castings, and/or an all-purpose organic fertilizer.
