Mar 18, 2021· Watering. The secret to properly watering a cast iron plant is to let the soil dry out completely between waterings. Poke your finger into the soil and if it feels dry, you're probably good to go. If you really want to make sure, poke a wooden stick like a chopstick down into the soil. If it comes out dry, it's time to water!
