How to Plant and Grow Rhizome Iris in Water

Rhizome iris is a beautiful flowering plant that can be grown in different ways. One of the most popular methods is growing them in water. This way, you do not need soil or a garden to grow these plants. Here are some steps to follow when planting and growing rhizome iris in water:

Choosing the Rhizome Iris Varieties

There are several varieties of rhizome iris that can be grown in water. Some of the popular ones include the bearded iris, Dutch iris, Siberian iris, Japanese iris, and Louisiana iris. Each variety has its unique colors, shapes, and sizes that can make your garden stand out. Before choosing the variety you want to grow, make sure that you have identified the right conditions for that type of plant. Understand the size of the plant, the water temperatures it needs, and the amount of sunlight it can tolerate.

Preparing the Water Container

You can use different types of containers when planting rhizome iris in water. The ideal one is a clear container, such as a glass jar or vase. This way, you can see the roots and the water levels as they grow. Fill the container with enough filtered or distilled water to cover the rhizome, but not too deep to drown it. You can also add some pebbles or marbles at the bottom of the container to keep the rhizome in place and prevent it from rotting.

Planting the Rhizome Iris

Before planting the rhizome in water, make sure that it is healthy and has no signs of disease or damage. Cut off any dead or diseased parts using a sterilized knife or scissors. Soak the rhizome in water for a few hours before planting to soften it and prevent air pockets from forming. Place the rhizome in the water container, making sure that the roots are facing downwards, and the crown is exposed to the air. Do not cover the rhizome with water or else it might rot.

Caring for the Rhizome Iris

After planting the rhizome iris, place the water container in a spot that receives indirect sunlight. Avoid placing it near direct sunlight or heaters as this might scorch the leaves and the roots. Change the water in the container every two to three days to prevent algae growth, and ensure that the water levels are maintained. Add some nutrients, such as fish or seaweed emulsion, to the water once a month to boost the growth of the plant. Watch out for any signs of pest infestation, such as spider mites, mealybugs, or scale insects, and treat the plant immediately using organic pesticides.

Harvesting the Rhizome Iris

Rhizome iris can be harvested after two to three years of growth. When harvesting, lift the rhizome gently from the water container and separate it into smaller sections, each with a piece of root and a shoot. Discard any rotten or diseased parts. You can plant the sections in a garden bed or in another water container to continue growing them. When planting in a garden, ensure that the soil is well-draining and enriched with compost or organic matter. Water the plants regularly during the growing season, and prune any faded flowers or leaves to promote new growth.

Planting and growing rhizome iris in water is a fun and creative way to add some color and beauty to your home or office. By following these steps, you can enjoy the sight and scent of these amazing plants without the hassle of soil or outdoor gardening. With proper care and maintenance, your rhizome iris can thrive in water for years to come.
