Step 3: Store the seeds in a cool, dry place or airtight container until the following spring, then plant in a well-drained soil, spaced about 8-12 inches apart. Step 4: Water and fertilize the seedlings regularly and watch as they grow and gradually develop the vibrant foliage and blooms of Canna ‘Pretoria.’

Asexual Reproduction

Asexual reproduction can be done through cuttings or division and produces plants that are identical to the parent plant. It is an efficient way to propagate plants since it ensures that the new plants will have the same characteristics as the parent plant.

Step 1: Choose a healthy Canna plant with multiple stems.
