The answer to the question is not as simple as it may seem. While most Kalanchoe plants will last for several years with proper care, some factors can influence their lifespan. For example, kalanchoe plants grown indoors typically have a shorter lifespan than those grown outdoors.This is because indoor conditions can be more stressful for plants, causing them to age prematurely. Additionally, Kalanchoe plants frequently exposed to direct sunlight or high temperatures may also have a shorter lifespan. With proper care, however, Kalanchoe plants can provide years of enjoyment.
