When placed in the right condition and given adequate care, the Monstera deliciosa can be expected to grow to about1 - 2 feet per year. As the plant grows bigger, it produces a new leaf in 4 – 6 weeks. The growth rate can either reduce or increase, depending on the environment and the care is given to the Swiss-cheese plant. You can boost your plant’s growth rate by exposing it to more light, and by watering it properly.
