8. Cut Back on Watering
As it prepares for dormancy, the plant really doesn’t need as much water in the colder months of fall and winter. With not enough sun to dry out the soil, overwatering could lead to fungal issues, root rot, and wilting foliage.
Water only if the soil is dry to the touch, and ensure it is tepid to avoid shocking the plant. Use only well-draining soil mix, and make ample drainage holes in the container.
9. Stop Fertilizing
A crucial thing to “not” do in fall is fertilize! Your peace lily is preparing to slow down, and any extra nutrients in the soil will actually stress it out rather than coax some surprise winter blooms.
Let your plant chill during this time so there is no build-up of salts in the soil, which could damage roots eventually. And when it’s spring, your peace lily will be well-rested, well-cared for, blooming, and thriving for years to come!
10. Give a Dose of Gibberellic Acid
You can chemically induce the plant into flowering if you’re desperate for all-season blooms. Gibberellic acid is a naturally occurring plant hormone extracted from fungi that can boost flowering in peace lilies, if you apply a foliar spray in 125, 250, or 375 ppm.
You can buy it from online stores or gardening centers. Always follow the instructions on the label before using it. This hormone helps start the growth of flower buds; the flowers appear at least 2-3 months later.
Note: Remember that plants are quite sensitive to this hormone, so use it rarely and avoid overuse, as it can kill the plant.
