They are very easy plants to maintain, to the point that it could be said that the difficult thing is to lose them. And it is that, as long as they have plenty of light and water, they will grow perfectly.

Origin and characteristics of Canna indica

The Canna indica are bulbous plants originating in Central America, but now you can find it in all the gardens in warm temperate climate around the world. They grow to a height of approximately 3m, and have beautiful leaves that can be green, reddish or purple depending on the variety. It also has flowers of different colors: yellow, red, bicolor… They appear in spring and summer, and remain until mid-autumn.

What are the care that must be provided?

Keeping a cane of Indias healthy is simple, but we recommend taking into account the following so that problems do not arise:


It has to be located in an area exposed, directly to the sun. But if you don’t have any available space at the moment, you can also have it in partially shaded areas, as long as it is very bright.


It will grow in all types of terrain, but although it is true that it will develop better in those that have good drainage and do not have a tendency to compact.

  • Garden: not demanding. It grows well even in limestone.
  • Pot: the container must have holes in its base, and be filled with universal substrate mixed with 30% perlite, claystone or fine construction sand.


Likewise, it will also appreciate being periodically fertilized with slow-release fertilizers, such as those you can get in nurseries or with worm castings, from spring to late summer.


If we talk about watering, this will have to be frequent, especially during the flowering season, since it does not tolerate drought. You can take advantage of the irrigation water, once a month, to add a little guano to fertilize your plant. In this way, you will have a greater number of flowers.

Planting or transplanting time

At the beginning of spring is a good time to plant it in the garden, or change it pot by following this step by step:

Planting in the garden

  1. First, you have to choose the location, taking into account that it must be watered very often, and that it requires direct sunlight.
  2. Next, dig a hole of about 12 “by 12” and fill it with water. Then wait for the earth to absorb it, something it should do in a few minutes. If you see that it takes a long time, make the largest hole, 50 x 50cm.
  3. Then, add a layer of about 10 centimeters (or 20cm if the soil has trouble absorbing the water) with fine sand, clay, volcanic clay or similar.
  4. Next, remove the plant from the pot or rhizome and place them in the center. If it is too high or far below ground level, remove or add more clay, volcanic clay,… or whatever you have used .
  5. Finally, finish filling with universal substrate.

Pot change

The change to a larger pot has to be done every 2-3 years, when you see that roots are coming out of the drainage holes, or the plant has occupied the entire container and cannot continue growing.

It is done as follows:

  1. First, choose a pot with holes in its base about 5-7cm wider and deeper.
  2. Then fill it in a bit with universal substrate.
  3. Then, remove it from its old pot, and place it in the new one, in the center. In the event that it is too high or low, remove or add dirt.
  4. Finally, finish filling, and water.


The Canna indica is multiplied by seeds and rhizomes in spring division:


Before sowing them, they must be soaked in water for 24 hours. Then, they are sown in seedling trays with peat or mulch, placed outside in semi-shade.

After a week or two, they will begin to germinate.

Rhizome division

When the plants reach 4-5 years of cultivation, the rhizomes can be divided and thus new specimens can be obtained. To do this, you have to dig them up and cut the aforementioned with a previously disinfected knife.

Afterwards, they are planted in individual pots or in other areas of the garden, and watered.


It can be attacked by aphids, mealybugs, borers, worms, and plusias (a type of caterpillars). Fortunately, they are not usually serious, and even then, they are fought well with natural products, such as neem oil or potassium soap.


Sometimes, when the soil is very compact and, in addition, it is watered too much, always keeping it flooded, the fungi will start to do their thing. The most common are Fusarium, Rhizoctonia and Alternaria.

When you see that they have dark spots on leaves and stems, treat them with fungicide and water less.
