Plants that Grow in Water: Herbs, Indoor Plants and more Plants

plants that can grow in water

Many indoor houseplants are types of plants that grow well in water. Growing plants in water is ideal if you want an easy way to look after plants indoors. Plants growing without soil requires less maintenance because they are less prone to pests and disease and they don’t need regular watering.

Of course, many plants only grow in water. These indoor water plants are generally suitable for aquariums or indoor water ponds. But this article looks at the best houseplants and other plants that grow well in jars or vases of water.

Growing indoor plants in water without soil is called hydroponic gardening. This water-only gardening method adds nutrition to water rather than relying on soil nutrients. The presence of essential nutrients helps plants live in water for a long time.

However this article is not about hydroponic gardening as done by commercial growers. In commercial hydroponic system the nutrients are delivered in very accurate quantities directly to the root system so the plants get exactly the amount of nutrition to maximize their growth.

Growing Plants in Water

You can propagate stem cuttings in a water bottle or a vase

Growing plants in water usually starts by placing houseplant cuttings in water to root them. Propagating plants in water is an easy way to root plants from the stem cuttings. It’s easy to root plants in jars, bottles, or water vases to grow new houseplants. Soon, you’ll have a tropical indoor water garden. These plants can grow in water for a few weeks or even months.

When your plant cuttings develop roots, you don’t need to transfer them to the soil. You can keep them growing in water vases or jars. In time, the indoor plants will grow new leaves, and they may even start to flower. The beauty is that growing plants this way is a lot less fuss and bother than growing in potting soil.

How to Grow Plants in Water

To grow your plant in water add a suitable fertilizer to provide enough nutrients for better growth

To grow plants in water, put a few houseplant cuttings in a jar or vase filled with water. The best type of container for growing plants without soil is a dark or opaque one. This prevents sunlight from causing algae growth. However, any glass jar, bottle, or vase is ideal.

For the best plant growth in a soilless medium, you’ll need more than just water. You can fill the jar three-quarters full with decorative pebbles, sand, colored marbles, or gravel. Mixing some charcoal with the soilless mix helps keep the water clear and fresh.

The next step to growing plants in water is to mix in some water-soluble houseplant fertilizer. This plant “food” provides plenty of nutrients in the water to promote healthy plant growth. This also substitutes for minerals that are usually found in potting soil.

When using the fertilizer to grow plants in water dilute it to one-quarter strength. If you grow a stem cutting, change the water every few days. If you grow an established plant, replace the water and nutrient solution every four to six weeks.

If you want to transfer a potted plant to a soilless environment, remove the plant root ball from the pot. Rinse off all traces of soil from the roots. “Plant” the houseplant in a water environment that has diluted fertilizer. Replace the water with the nutrients every four to six weeks.

The last step is to find some suitable houseplants that grow in water.
