How long do cycads live?
Incredibly, those ancient plants, called cycads, have been around for millions of years. A single cycad plant can live up to 2,000 years! We think that the secret to cycads' survival and long life lies inside a very special structure called the coralloid root, which has microbes living inside it.Jan 23, 2020
What is the lifespan of a cycad?
Cycads are incredibly long-lived, with some individuals in the wild estimated to be around 1,000 years old. One of the oldest cycads “in captivity” is in Kew Gardens in London, and it at least 228 years old. Part of the secret of their longevity is that they grow very slowly – producing just a few leaves each year.

The most common way our cultivated cycads die is from the rotting of stems and roots. Most people will see their plant stop growing and wonder what is wrong, but do nothing. This is the first sign of root rot. They will wait until the leaves collapse before they wonder if something is wrong with their plant.
