Cacti are slow growers and can live for many years. While they may look tough and resilient, they need to be given the right environmental conditions to thrive.
Cacti have adapted to survive long-term droughts and high temperatures, so they don’t need too much water or maintenance. That said, they should still be given regular light exposure. Cactus need at least four hours of sunlight each day in order to grow properly, though some night-blooming varieties do better in indirect light.
For maximum longevity, cacti should be potted in well-draining soil and watered only when the soil has completely dried out – typically once every few weeks during late spring through autumn. In winter, when growth slows down drastically, water less frequently or not at all. Keeping your cacti dry can also help protect them from rot caused by overwatering.
Extra attention should also be given to fertilizing cacti periodically with a balanced liquid fertilizer diluted to half strength once every three months during the growing season. And pests should never be ignored because, if left untreated, they can cause irreversible damage to the plant’s health. Proper humidity levels are also important; this succulent needs at least 30% humidity throughout its life cycle for optimal longevity.
The average lifespan of a cactus is determined by its species; larger barrel cacti usually live between 50–100 years, while smaller types, such as desert globemallow, tend to last longer – up to 150 years – with proper care and environmental conditions. With that being said, one can ensure maximum life expectancy for their cactus when adhering to its specific needs over the long term!
