QuestionI have seeds from this year's canna lilies that were given to me. How and when do I start the seeds, please?
AnswerHi Cynthia,
Thanx for your question. Canna seeds are easy to germinate. I wouldn't start them until February of next year. The seeds have a hard outer coating. Rub some of this off with some sandpaper until the brown or black coating gives way to a lighter color. Soak the seeds for a couple of days in warm, clean water. Plant about 1/2 inch deep in potting soil and keep warm (about 75-80癋.). They should germinate in a couple weeks and will look like thick grass coming up. Transplant to separate pots when large enough to handle. Keep under 40-watt shop lights until well after last frost, when ground is warm. Put in shade for about a week to acclimatize and then full sun. Canna rhizomes must be lifted in the autumn if your area is not frost-free. I hope this helps.
