Can Canna be grown hydroponically? Hydroponic methods and care tips
Canna can be grown not only in pots or in the ground, but also hydroponically or as a marsh plant. When grown in water, it is mostly seen as a shallow-pond marsh plant or cultivated on floating bases, drifting on the water surface. It can purify water quality and is also somewhat helpful for purifying the environment.
Now that you know whether Canna can be grown hydroponically, let's look at the hydroponic methods and precautions!

Canna can be grown not only in pots or in the ground, but also hydroponically or as a marsh plant. When grown in water, it is mostly seen as a shallow-pond marsh plant or cultivated on floating bases, drifting on the water surface. It can purify water quality and is also somewhat helpful for purifying the environment.
How should Canna be grown hydroponically?
For hydroponics, generally choose a ceramic jar or a goldfish bowl, and select a Canna variety suitable for hydroponics. You can first grow seedlings from rhizomes, or use sown seedlings about 30 cm tall, which is more conducive to the growth of Canna.
Fix the plant in the vessel to be used for growing. If glass beads or something else are used as filler, just fix the roots and let the plant stand upright, just like planting in soil.
If a planting basket is used, pass the plant's roots through the holes of the planting basket so they can reach the nutrient solution below, then fix them with some coarse sand, small gravel or similar materials.
After that, add water mixed with nutrient solution to the container, but do not submerge all the roots; leave some space. Place the container in the sunlight to ensure the plant fully absorbs sunlight.
Precautions for hydroponic Canna
In summer, the container should be placed outdoors where direct sunlight does not reach, to absorb scattered light; in winter, place it on the sunny side of the room.
In summer, change the water once a week; in other seasons, extend the interval by one week each time. Tap water should be left standing for 10 hours or exposed to sunlight for 2 hours before use. While changing the water, add 1-2 drops of nutrient solution.
Mist the leaves of the Canna every day, keeping it to more than 2 times, to maintain leaf humidity and moisture.
Keep indoor air circulating and pay attention to ventilation. If the Canna develops root rot, simply trim off the rotten roots and replace with clean water.
Hydroponic methods for Canna
Method One
Dig out small soil-grown Canna seedlings, remove the rotten parts of the roots and old roots, disinfect in a 0.05%-0.1% potassium permanganate solution for about 10 min, then after rinsing, plant them in a transparent container and pour clean water into the container up to 2/3 of the roots. Change the clean water once every 2-3 days; they root very easily, and hydroponic roots can grow in about 10 days.
Method Two
Dig out Canna rhizomes, divide them into small pieces, each piece with 2-3 buds and a few fibrous roots, rinse the roots, then plant them in a hydroponic container. Change the clean water once every 2-3 days; after 2 weeks, hydroponic roots can grow.
