How to Propagate Houseplants in Water: A Simple, Step-by-Step Guide

Table of Contents

One of the most rewarding aspects of houseplant care is propagation growing new plants from your existing ones. Among the many propagation methods, water propagation is perhaps the easiest and most satisfying, especially for beginners. With just a healthy plant, clean water, and a little patience, you can create a thriving indoor jungle at little to no cost.

In this guide, we’ll walk you through everything you need to know about propagating houseplants in water from choosing the right plants to ensuring successful root development.

Why Propagate in Water?

Water propagation is a popular choice because it's:

• Simple and low-maintenance

• Fascinating to observe you can literally watch roots grow

• Effective for many popular houseplants

• A mess-free way to start propagation indoors

Best Houseplants for Water Propagation

Not all plants respond well to water propagation, but many houseplants do. Here are some top candidates:

• Pothos (Epipremnum aureum)

• Philodendron

• Spider plant (Chlorophytum comosum)

• Monstera deliciosa

• ZZ plant (Zamioculcas zamiifolia) – leaf or stem cuttings

• Tradescantia (Wandering Jew)

• Coleus

• Begonia

• Chinese evergreen (Aglaonema)

What You’ll Need

• Healthy parent plant

• Clean, sharp scissors or pruning shears

• Clear glass jar or vase

• Filtered or dechlorinated water

• Optional: rooting hormone (for slow-rooting plants)

Step-by-Step: How to Propagate Houseplants in Water

Step 1: Select a Healthy Cutting

Choose a healthy stem with at least 2–3 nodes (the points where leaves grow from the stem). Make a clean cut just below a node.

Pro tip: Remove the leaves on the lower part of the stem these can rot if submerged.

Step 2: Place the Cutting in Water

Use a clear glass container filled with filtered water. Position the stem so that at least one or two nodes are submerged.

Avoid: Submerging any leaves they’ll rot and contaminate the water.

Step 3: Provide Indirect Light

Place the jar in a warm, bright area with indirect sunlight. Too much direct sun can overheat the water or encourage algae growth.

Step 4: Change the Water Regularly

Change the water every 3–5 days to prevent bacterial growth and maintain oxygen levels. Use room temperature water.

Step 5: Wait for Roots to Develop

Depending on the plant, roots can appear in 1–4 weeks. When the roots are about 2–4 inches long, they’re ready to be transferred to soil or continue growing in water.

Transferring Cuttings to Soil

Some plants can live indefinitely in water, but most will benefit from being potted once roots have matured.

• Use well-draining potting soil.

• Water thoroughly after transplanting.

• Place in the same indirect light environment to reduce transplant shock.

Tips for Successful Water Propagation

• Use clear containers to monitor root growth.

• Label jars if you’re propagating multiple types of plants.

• Use rooting hormone for tougher cuttings like woody stems (optional).

• Clean your tools before cutting to avoid spreading disease.

Common Problems and Solutions

Plants You Can Grow Permanently in Water

Some plants can grow in water for years with proper care:

• Lucky bamboo

• Pothos

• Peace lilies

• Philodendron

• English ivy

Add a few drops of liquid fertilizer once a month to keep them thriving.

Conclusion

Water propagation is a simple, effective, and enjoyable method to expand your houseplant collection. With a little patience and care, you can grow vibrant new plants while gaining a deeper appreciation for how life begins and grows. Whether you’re a seasoned plant parent or a beginner, propagating in water is a fun way to deepen your connection with your plants and your indoor garden.
