The Natural Aging Process of Cacti
As said previously, your cactus is all young and vibrant, showing off its radiant green coat. But as it matures, you notice something curious—it starts to turn gray. Why is this the case? My friend that is just nature doing what it does.
Corking: The Aging Superpower
Cacti, like fine wine and cheese, get better with age. They develop a unique superpower called corking. Here’s the deal:

- Why Does It Happen?: Think of it as a defense mechanism. As cacti age, they need protection from harsh sun and potential predators. Corking provides that extra layer of defense, making them resilient in their natural habitat.
Embrace the Gray
So, should you panic when you see your cactus getting its grey on? Absolutely not! It’s a natural part of their life cycle like humans getting wrinkles as they age. In fact, many cactus enthusiasts adore the unique beauty that corking brings to their prickly pals.
Shedding Light on Cactus Color

A Gray Reality
