Peace lilies fail to bloom again because of improper care. Owners need to provide these houseplants with adequate light, moist soil, and the correct temperature and humidity to bloom again. Blooming can also depend on the variety of plants, as some peace lilies only bloom once a year during their blooming season.
Ben Hilton, founder and editor of The Yard and Garden has shared several mistakes peace lily owners should avoid, so that they can encourage their houseplants to bloom.
Improved watering has adverse effects on the overall health of the peace lily. Overwatering is a common mistake that keeps the soil damp most of the time. This leads to root rot as the roots suffice by staying in the damp soil all the time.
The roots fail to function and provide water and nutrients to the plant, creating an extremely harmful environment. Therefore, an overwatered unhealthy peace lily fails to grow or bloom.
The expert said: “Peace lilies are sensitive to overwatering, as they prefer moist soil, not soaking wet, and certainly not sitting in water. It’s only essential to water when the soil is drying out.

“Use the finger test, push your finger one inch into the soil, and feel for moisture. If it’s dry, water the plant thoroughly and allow the water to drain into the sink.”
2. Lack of drainage
Soil could also be the reason why the peace lily doesn’t flower. If the soil has a poor drainage system, it can cause overwatering.
Soil with a high clay content will cause overwatering as the clay will hold more water for an extended period, whereas sandy soil will drain water very quickly, making the soil dry too quickly.
Ben explained: “Insufficient drainage can cause the soil to become waterlogged, leading to root rot or other forms of bacteria or fungal infection.”
He noted that if a peace lily “has to battle with any form of disease”, it has “no chance of producing blooms”.
Adding compost to the potting soil can help make a sound drainage system. It will help in both retaining moisture and draining water.
3. Insufficient light
Peace lilies are “in need” of bright, indirect, filtered light in order for them to bloom. The expert said: “They are often placed in full direct sun or dark corners, where they simply won’t perform.
“Aim to locate them in a bright room or near a North or East facing window.” These directions will give the plant the right amount of sunlight.

For those who keep them near a south or east facing window, use curtains whenever the sun rays become intense.
Pull down the curtains to create a filter for direct sunlight. This will give the plant perfect indirect sunlight.
4. Low humidity
Peace lilies are native to tropical regions and therefore enjoy humidity. If the air is too dry, try misting the leaves twice a week. Alternatively grouping the houseplants together will also increase humidity.
5. Lack of fertilizers
Without proper feeding, peace lilies may not have the nutrients needed to produce blooms, warned Ben.
He explained: “All plants need nitrogen to create amino acids, which are the building blocks of proteins and cell production.
“Without nitrogen, your peace lily won’t be equipped to develop new plant tissues and flowers.”
6. Ignoring the plant’s health
Peace lilies are relatively easy to care for, but they still need to be given some love.
The expert said: “Removing yellow or brown leaves, checking leaves for pests, and using a well-draining soil mix can help ensure the plant’s overall well-being and promote blooming.”
