Ferns are stunning plants that deserve to be on display—and one of the most elegant ways to showcase them is by growing them in water and using them as eye-catching centerpieces.
One of the most beautiful plants for hanging baskets, ferns can also look stunning when displayed in vases or glass terrariums. If you don’t want to grow them in soil, you can still enjoy their lush greenery by learning how to grow ferns in water. With a few simple steps, these plants can thrive beautifully indoors.
Can Ferns Grow in Water?
Yes, ferns can grow in water as long as their roots are kept intact. Fern fronds without roots won’t grow but can stay fresh for a few days. To keep them alive long-term, always place the plant along with its roots in a vase or glass bowl filled with clean, non-chlorinated water. For best results, ensure your fern gets a few hours of gentle morning sunlight and bright indirect light during the day. Regularly change the water to keep it fresh and clear.
How to Grow Ferns in Water
Start by selecting a healthy section of the plant that has both roots and fronds. Rinse the roots gently under running water to remove soil and trim away any damaged or rotten parts. Place the fern in a clear vase or bowl and add small gravels to keep the roots in place—this also helps the plant stay upright. Fill the container with non-chlorinated water, making sure only the roots are submerged while the leaves and fronds remain above the surface.
Light
Ferns love bright, indirect light. Keep them near a window with filtered sunlight, and avoid placing them under direct afternoon rays, which can scorch the leaves.
Water
Change the water once every week or sooner if it looks cloudy. This prevents algae growth and keeps the roots healthy. Adding a small amount of aquarium water every few weeks can also provide natural micronutrients.
Container Care
Clean the vase or bowl every three to four weeks. Remove the plant carefully, scrub the inside of the container, rinse thoroughly, and refill it with fresh water.
Fertilizer
Ferns grown in water need very little fertilization. Use a weak liquid fertilizer once a month or sprinkle a pinch of balanced plant food powder every couple of weeks.
How Long Can Ferns Live in Water?
With proper care, ferns can live and grow indefinitely in water. Just ensure they receive bright, indirect light and that the water is changed regularly. However, if you’re keeping only fern fronds without roots, they’ll typically last one to four weeks before wilting.
Benefits of Growing Ferns in Water
Growing ferns in water makes them easy to maintain and keeps them free from soil pests. It prevents problems like overwatering or underwatering, which often damage houseplants. Because the roots are constantly in a humid environment, there’s no need for misting. These water-grown ferns also make elegant centerpieces for tables, shelves, or office spaces.
Best Ferns to Grow in Water
Some of the best types include Asparagus Fern (Asparagus setaceus), Boston Fern (Nephrolepis exaltata), Japanese Lace Fern (Polystichum polyblepharum), Bird’s Nest Fern (Asplenium nidus), Maidenhair Fern (Adiantum), Asian Water Fern (Bolbitis heteroclita), and Java Fern (Leptochilus pteropus).
With a bit of care, your fern will stay vibrant and healthy in water, bringing a touch of fresh green beauty to your home all year round.
