The tubers have survived the winter without any damage and should now get a taste of fresh air. Whether you grew your canna plant at home or not, the same rules apply when planting out.
When and how should you plant canna plants?
Canna plants should only be planted out from mid/late May to avoid frost damage. Choose a warm, sunny to partially shaded location and pay attention to moist soil with a high humus and nutrient content and a pH value of 5 to 6. The planting holes should be two to three times as deep as the tuber diameter.
When can you plant canna?
Canna is considered extremely sensitive to frost. Therefore, the plant or its rhizome should only be planted out from mid/late May. Pay attention to the weather forecast! In the past, Canna should not be planted out without protection. If you made the mistake of being too impatient and Canna suffered frost damage: You can plant Canna out until June.
Hardening is recommended
Caution: The young canna plants grown at home are sensitive. It is advisable to slowly get them used to the cool outside temperatures. To harden them off, you should put them outside every day for about a week, for example on the balcony or terrace. In the evening the plants are brought back into the house.
What location is required?
When planting Canna, regardless of whether the plant is to grow in a pot on the balcony or outdoors in the garden, the location should not be ignored. Canna needs a warm, sunny to partially shaded location that is preferably sheltered from the wind.
The soil should be kept moist, because as a tropical plant, the flower cane needs a lot of water. Other characteristics that the substrate should have are:
- high humus content
- high nutrient content
- pH value between 5 and 6
- good permeability
How deep are the tubers buried?
The tubers of Canna are placed in the soil. The planting hole should be two to three times as deep as the diameter of the tubers. You should not water after planting. Only water when the first leaves have formed.
Tips & Tricks
When planting, remember to keep a proper distance from other plants! Depending on the species and variety, you should maintain an average planting distance of 50 cm.
