Canna likes warm, humid and sunny environment, and is usually planted in February-April in spring or August-September in autumn. The climate in these two periods is more suitable for its growth, which is conducive to seed germination and easier survival. Of course, the specific time still depends on the climate in the planting area.
It is best to choose a slightly acidic soil with loose and fertile soil and good drainage for planting canna, and choose a planting site suitable for its growth. Then, the land should be sorted out, and the soil should be deeply dug and loosened, and sufficient fertilizer should be applied to provide a good soil environment.
Precautions:
Canna doesn't need to be watered too much soon after planting, as long as the soil is not dry. In the peak season and flowering period, it is necessary to keep the soil moist and increase the amount of watering, but not too much to avoid water accumulation in the soil.
In addition, canna likes fertilizer, so it should be fully fertilized before planting, topdressing once a week before flowering in the growth period, diluting and fertilizing organic fertilizer with water, and not fertilizing at flowering period.
