How to make more plants for free
There’s something magical about watching new roots unfurl in a simple glass of water. Water propagation is one of the easiest, most satisfying ways to multiply your favorite plants. Whether you’re a seasoned gardener or a total beginner, water propagation opens a window into the hidden beauty of how plants grow.
In this guide, we’ll cover everything you need to know about propagating plants in water – from the best plants to try, to step-by-step tips for rooting success.
Why Propagate Plants in Water
Water propagation offers a few major advantages for home gardeners
- Simplicity – No need for special soil mixes or rooting hormones. Just water and patience.
- Visibility – You can actually watch the roots develop day by day, which is both educational and incredibly rewarding.
- High Success Rates – Many plants root easily in water, giving beginners a big confidence boost.
- Clean and Easy – No messy potting soil or complicated setups needed.
Best Plants for Water Propagation
While not all plants are suited to water propagation, many houseplants and garden favorites thrive with this method. Some of the easiest plants to propagate in water include
- Pothos – Practically indestructible and roots quickly
- Philodendron – Another easygoing vining plant
- Spider Plant – Baby “pups” root readily in water
- Coleus – A colorful annual that roots almost overnight
- Mint – Great for culinary gardens, roots in just a few days
- Tradescantia (Wandering Jew) – Fast-growing and colorful
- Basil – Fresh cuttings root easily and give you an endless herb supply
- Hydrangea – Soft green stems root nicely in water with a little patience and help from rooting hormone
Master Gardener Tip – Plants with softer, fleshy stems tend to root better in water. Woody plants or shrubs usually prefer soil propagation instead.
How to Propagate in Water – Step-by-Step
- Choose a Healthy Stem Cutting
Select a healthy stem with no signs of disease or damage. Ideally, the cutting should be 4-6 inches long and have a few leaves attached. - Make a Clean Cut
Use sharp, sterilized scissors or pruning shears to make a clean cut just below a node (the spot where a leaf meets the stem). This is where roots are most likely to form. - Remove Lower Leaves
Strip away any leaves that would sit below the water line. Submerged leaves can rot and spoil the water. - Place in Water
Fill a clean glass or jar with room-temperature water and place the cutting in it. Make sure at least one node is underwater. - Provide the Right Light
Set your jar in a bright, indirect light location. Direct sunlight can cause algae to grow or scorch delicate cuttings. - Change the Water Regularly
Every 2-3 days, change the water to keep it fresh and oxygenated. Rinse the glass if you notice any buildup. - Wait for Roots
Roots can take anywhere from a few days to a few weeks to appear, depending on the plant. Be patient and celebrate each new white rootlet you see. - Pot Up When Ready
Once the roots are 1-2 inches long, you can transplant your cutting into potting soil if desired, or continue to grow it in water for a minimalist look.
Master Gardener Tip – If you want to give your cuttings an extra boost, you can dip the stem ends lightly in rooting hormone before placing them in water. Itβs not necessary for most soft-stemmed plants but can help stubborn cuttings like hydrangea root faster and develop stronger root systems. Use a very light dusting and avoid overapplying, as too much can cause rot.
Common Mistakes to Avoid
- Letting Leaves Sit Underwater – This causes rot and can spoil the whole jar.
- Using Dirty Water – Fresh, clean water is key to healthy root growth.
- Putting in Direct Sun – Too much sunlight can overheat the water or encourage algae.
- Rushing to Pot Up – Let the roots get well-established before moving to soil for the highest success.
Fun Ideas for Displaying Water Propagations
- Arrange multiple glass jars of propagations on a sunny windowsill
- Use vintage bottles or mason jars for a rustic touch
- Hang cuttings in test tube wall vases for a modern plant art piece
- Create a mini indoor jungle by mixing several types of plants in one large clear vase
Final Thoughts on Water Propagation
Propagating plants in water is a joyful, simple way to expand your plant collection, share plants with friends, or just enjoy the miracle of growth up close. With a few easy steps, you’ll be growing a whole new generation of greenery in no time.
Some plants like pothos, mint, and spider plants will root practically overnight, while others like hydrangeas may take a little longer and appreciate a dusting of rooting hormone to help them along. No matter which plants you choose, watching those first little roots appear is always a thrill.
Grab a cutting, a glass of water, and let the magic begin.
