Comments. Submit. Canna seeds germinate in about one week. When you plant rhizomes in the ground at an average depth of 2 to 3 inches, canna seeds sprout within a few days to a few weeks.The key determinants are heat, moisture and soil conditions, along with rhizome species, size and quality.hen you plant rhizomes in the ground at an average depth of 2 to 3 inches, canna seeds sprout within a few days to a few weeks.
Soil temperature is a significant influence on the rate of canola germination and emergence. Canola can germinate at temperatures as low as 2-3 Â°C, but germination rates are lower and slower, with seeds germinating over a period of weeks. At 6 Â°C, close to 100% germination can occur within 8 days.Figure 1.oil temperature is a significant influence on the rate of canola germination and emergence.
