In recent years, the trend of growing plants in water has gained popularity. So, can cannas be planted in water?

The Short Answer

Yes, cannas can be planted in water. In fact, they are one of the few aquatic plants that can thrive both in soil and water. However, growing cannas in water requires a different approach than growing them in soil, and there are a few things you need to know before starting your water garden with cannas.

The Benefits of Growing Cannas in Water

There are several benefits to growing cannas in water. Firstly, you can enjoy the beauty of the plants without the need for soil, which can be messy and require frequent maintenance. Secondly, growing cannas in water can help to purify the surrounding air and water, making them great additions to ponds and other aquatic environments. Lastly, growing cannas in water can be an exciting and unique way to showcase your gardening skills and add some natural beauty to any indoor or outdoor space.

How to Plant Cannas in Water

Planting cannas in water is relatively simple, but it requires some planning and attention to detail. Here are the steps for planting cannas in water:

Choose a container or vase that is at least 10 inches deep and wide enough to accommodate several cannas.

Place a layer of pebbles or stones at the bottom of the container to create some stability and help with drainage.

Add clean water to the container until it reaches a depth of around 3-4 inches.

Place the cannas in the container, making sure that the roots are submerged in water but the crowns of the plants are above the water line. If the crowns are submerged, they may rot.

Place the container in a spot that receives bright, indirect sunlight. Cannas need at least six hours of sunlight per day to thrive.

Change the water in the container at least once a week and add a water-soluble fertilizer to the water every month to feed the plants.

Caring for Cannas Planted in Water

Once you have planted your cannas in water, there are a few things you need to do to ensure that they continue to thrive:

Monitor the water levels regularly, and top up the container with fresh water as needed to maintain a depth of 3-4 inches.

Trim the dead leaves and flowers from the cannas regularly to keep them looking tidy and healthy.

Check the water quality regularly and change the water if it becomes cloudy, foul-smelling, or if algae begins to grow.

If you notice any pests or diseases on the cannas, remove them immediately to prevent them from spreading.

Conclusion

Cannas are versatile and hardy plants that can be grown in both soil and water. While growing them in water requires some additional care, the benefits are well worth it for the beauty and natural purification they can add to any indoor or outdoor space. So, if you are looking for a unique and exciting way to showcase your gardening skills, try planting cannas in water and enjoy the beauty and tranquility they bring to your life.
