A Jar Of Water Is All You Need To Grow More Gorgeous Peace Lily Plants

Peace lilies are among the most elegant and forgiving houseplants you can own. Their deep green, glossy leaves paired with graceful white blooms make any room feel brighter, fresher, and more curated. What most homeowners don't realize, however, is how simple it is to multiply these beauties. You don't need expensive tools, complex soil mixes, or advanced gardening skills — just a simple jar of water and a little patience. Water propagation is one of the most satisfying methods for creating new peace lilies, as it puts the entire process on display around your home. Instead of digging in the soil and hoping that the roots are healthy, you have a front row seat to watch the roots grow, stretch, and thicken in real time. For anyone who has ever felt intimidated by houseplant propagation, this method removes the guesswork entirely, turning it into a small, manageable project that you can enjoy.

There are plenty of ways to reuse old glass jars around the house, but propagation is one of the best, as it results in a new houseplant without harming the original. This method works so well with peace lilies because they like to grow in clumps. These clumps can be carefully divided and each segment is capable of producing new growth on its own. It doesn't require extensive research or advanced gardening knowledge to pull off either. Once placed in water, the roots adapt quickly and continue developing without needing soil. The transparency of the glass allows you to monitor root growth and adjust for any problems that may arise, like root rot or stagnant water, before they seriously damage your plant. 

Start by gently removing your peace lily from its pot and rinse off any soil around the roots. This allows you to see exactly where the plant naturally divides into smaller clumps. Peace lilies grow in clusters, so you'll likely notice baby off-shoots emerging from the base of your original plant. Each of these sections is potentially a new plant, provided it has a few healthy leaves and a viable root system. Carefully separate the offshoot from the parent plant, taking care not to damage any delicate roots. You may need to trim your peace lily's roots, especially those that are brown or mushy. The goal is a clean, healthy division that will thrive in its new watery home. Taking your time here pays off — it may feel delicate, but patience is rewarded with a cutting that is ready to grow vigorously.

Next, choose a clear glass jar or vase that allows the roots to be fully submerged while keeping the leaves above the waterline. Fill the container with room-temperature, chlorine-free water and place it in a location with bright, indirect light. Avoid direct sunlight, as it can scorch the leaves and promote algae growth in the water. Refresh the water weekly to maintain oxygen levels and remove any debris, giving the roots an ideal environment to grow. Over the next few weeks, you'll notice that the roots begin to elongate, thicken, and branch, confirming that your cutting is adjusting nicely. Watching this process unfold is surprisingly satisfying and by the end of this stage, your cutting will have healthy, visible roots that are ready for long-term growth options; either in soil or water.

Once your peace lily has established a strong set of roots in water, you'll be faced with an exciting decision: Keep it growing in water indefinitely or transition it back into soil. Many homeowners enjoy displaying their peace lilies in clear glass containers, where the intricate roots become part of the decor. If you choose to keep it this way, refresh the water weekly to prevent buildup or stagnation. You'll also want to provide nutrients through a diluted liquid fertilizer about once a month. Because water lacks the natural nutrients found in soil, this step is essential for keeping the plant lush and vibrant. With a few small adjustments, peace lilies can thrive in water for months or even years, making them perfect for homeowners who prefer low-maintenance greenery.

If you decide to pot your propagated cutting, wait until the roots look strong — usually a few inches long — and well developed. Choose a container with drainage holes and fill it with light, well-draining mix to prevent soggy roots, which peace lilies ironically dislike. Plant your rooted division carefully, water it thoroughly, and then place it in a spot with the same indirect light conditions that it enjoyed previously. This transition gives the plant access to soil nutrients and may encourage fuller growth and more frequent blooms. The best watering method for peace lilies is typically when the soil feels dry to touch, which may depend on how active the plant is. Whether you decide to plant in water or soil, propagation allows you to expand your collection affordably and enjoy vibrant blooms all around your home.
