The cast iron plants grow wonderfully in dim and airy spaces. Although they can survive in direct sunlight, keep the plant away from direct sunlight as it may burn the leaves. While using the aspirada as an indoor plant, you may place it near north-facing windows, but further away from other windows. When placed outside, the plant should be kept in shady areas hidden away from direct sunlight. 


Although the cast iron plant is wondrously drought-tolerant, it thrives well in humid environments and does need some water, especially when the top inch of its soil becomes dry. However, don’t overwater the plant as it may cause root-rot which can further result in the death of the plant. You can reduce the frequency of watering the aspirada during winters. 


In outdoor environments, sandy or clay soils are suitable for the plant’s growth. While using the cast iron plant as a houseplant, the potting soil in the compost base should maintain a ph value between 5.5 to 6.5. 


Although the aspirada elatior enjoys humidity, it is not an important factor for the plant. 


The cast-iron plants aren’t too fussy about temperatures. However, the suitable range of temperature for their growth is 7 to 9 degrees Celcius /45 to 85 degrees Fahrenheit. When the plant is being grown outside in a container, it is advisable to bring it back indoors when the temperature drops so it can continue to grow comfortably in a relatively warmer environment. 


In the months of summer and spring, fertilize your aspirada plant every fortnight with an all-purpose liquid fertilizer. You can skip the fertilization step during the fall and winter months. To avoid the burning of the plant roots, the fertilizer should be applied only after watering the plant. However, it is important to remember that even after fertilization the growth of the plant remains slow and steady.

Browning or yellowing of leaves

This change in the color of leaves occurs mostly due to waterlogged soil or exposure to direct sunlight. Keep it in mind to not overwater your plant and place it away from direct light. Furthermore, use clean scissors or a blade to cut off any damaged leaves from the base of the stem. 

Brown tips of leaves

The most likely cause for the browning tip of the iron plant is under-watering. Although known for its resilience, the plant should not be neglected for too long. Another probable reason for the brown tips can mineral accumulation. Especially in the areas where the mineral content of the tap water is too high. To solve this problem, leave a watering can out overnight before you water the plants.

Speckles or discoloration of leaves

The cast-iron plants are susceptible to pests such as spider mites that result in the appearance of small speckles on the leaves. You can save your plant by washing it with cold water to shed off the webs and mites and further treating the infested areas with neem oil or any other natural pesticide.
