What are the precautions for growing canna lilies (Canna spp.) in water?
In summer, the container should be placed outdoors in a spot without direct sunlight so the plant receives diffused light; in winter, place it on the sunny side of a room.
In summer, change the water once a week, and push the interval back by one week in each of the other seasons. Tap water should be left to sit 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 lily more than 2 times every day to keep the leaf surface humid and supplied with moisture.
Keep the indoor air circulating and pay attention to ventilation. If the canna lily develops root rot, simply trim off the rotten roots and replace the water with clean water.

Canna Lily Water Culture Care Guide
1. Light and temperature
When the plant is in bloom, place it in a ventilated, cool spot to extend the flowering period. In an environment where the temperature stays above 16°C all year round, the plant can bloom throughout the year. When the temperature drops below 16°C, growth slows or the plant even goes dormant. In winter, it can overwinter safely when the room temperature is not lower than 7°C. In winter, place it in a spot with ample light and keep the room temperature above 7°C for safe overwintering; below 7°C it is prone to cold damage.
2. Fertilizing
After the roots of the canna lily are washed and the plant is moved to water culture, new roots tend to form easily, and lateral roots also develop quickly. After 2-3 weeks it begins to show strong growth, at which point you can switch to nutrient solution and keep it in a spot with ample diffused light. Because it is extremely fond of fertilizer and tolerant of moisture, be sure to add an appropriate amount of nutrient solution every week and replace it about once every 3 weeks.
3. Watering
In the hot summer season, avoid scorching sun exposure and mist the leaves frequently; otherwise the leaf margins will scorch and turn yellow.

Can canna lilies be grown in water?
Canna lilies can be grown not only in pots or in the ground, but also in water culture or as marsh plants. Those cultivated in water are mostly seen growing in shallow ponds and marshes or grown on floating bases, floating on the water surface. They can purify water quality and are also somewhat helpful for purifying the environment.
Now that you know whether canna lilies can be grown in water, let's look at the water culture method and precautions!
