How to propagate houseplant cuttings in plain water
Propagating houseplants from cuttings is one of the easiest and most satisfying ways to grow your indoor garden. With just a pair of scissors, a small bottle, and some water, you can turn a few stems into brand-new plants. Deal with scraggly growth and make new plants at the same time! There are so many trailing houseplants that root very quickly this way, and one of the easiest examples is Tradescantia. Its fast growing vines and visible nodes make it perfect for learning how water propagation works.
Taking cuttings is also a great way to improve the appearance of your plants. Trailing plants can sometimes become long and sparse over time. By rooting a few cuttings and planting them back into the pot, you can restore fuller, bushier growth without resorting to trashing old plants and buying new. Best of all, propagating houseplant cuttings in plain water is simple, fun to watch, and usually takes only a couple of weeks from cutting to planting.
How to propagate houseplant cuttings in plain water
Before you start, make sure you choose the right houseplant. If a plant has visible nodes along the stem, there’s a good chance you can propagate it in water. Some common houseplants that propagate well from cuttings in plain water include:
- Tradescantia – Our example in this article
- String of Hearts (Ceropegia woodii) – It’s delicate vines with heart shaped leaves root easliy from stem nodes
- English Ivy (Hedera helix) – Trailing stems root easily from nodes and can quickly grow into new plants
- Pothos (Epipremnum aureum) – One of the easiest and fastest plants to propagate in water
- Heartleaf philidendron (Philodendron hederaceum) – Roots quickly from stem cuttings and grows well after replanting
1 ~ Take healthy cuttings
Start by choosing a healthy stem from your plant. Look for one with several leaves and strong growth. Using clean scissors or pruners, cut the stem just below a node, which is the small bump on the stem where leaves grow. Nodes are important because this is where new roots sprout from. For most houseplants, cuttings around 8–12 cm long work well. If the cutting has leaves near the bottom, gently remove them so they don’t sit in the water and rot.
2 ~ Choose a suitable container
Next, select a small container for rooting the cuttings. Bottles with narrow necks are ideal because they help hold the stems upright and prevent them from slipping fully into the water. Small glass jars also work well. A great recycling option is an empty reed diffuser bottle, which is often the perfect size for plant cuttings and looks attractive on a windowsill.
3 ~ Fill the container with water
Fill your container almost to the top with fresh water. Room-temperature water works best, and filtered water can help prevent mineral buildup in some cases. Since the cuttings will stay in the container for several days, it’s a good idea to check the water occasionally and top it up if needed.
4 ~ Place the cuttings in container
Place the cuttings into the container and make sure that at least one node is submerged in the water. This is the most important part of the process, since the roots will grow from this point on the stem. Try to keep the leaves above the waterline so that they remain dry and healthy (submerged leaves are likely to rot).
5 ~ The rooting process
Set the container somewhere with bright, indirect light. Over the next several days you’ll start to see some exciting changes. With fast-growing plants like Tradescantia, tiny roots might start forming within a few days. Once you see these tiny roots, allow the roots to grow until they are about an inch long (2-3cm). This usually takes one to two weeks depending on the plant and the conditions in your home.
6 ~ Replant the cuttings in soil
Once the roots are established, it’s time to move the cuttings into soil. Fill a pot with fresh potting mix and use a pencil or chopstick to poke small holes in the soil. Carefully place the rooted cuttings into these holes so the delicate roots are not bent or damaged. Then gently cover the roots with soil and press lightly to hold the stems in place.
7 ~ Enjoy a fuller bushier plant!
Water the pot lightly after planting and place it back in bright, indirect light. As the cuttings settle in and start growing, they will fill in the gaps in the original plant. The result is a lush, bushy plant instead of long, scraggly vines, all created from just a few simple cuttings. If your mother plant looks good, plant the cuttings into new pots to make new baby plants!
Once you’re familiar with this technique, you can try it with many other houseplants as well. Water propagation is an easy way to multiply your favorite plants, share cuttings with friends, and keep your indoor garden looking full and healthy.
