Luckily, propagating cannas from bulbs is a relatively straightforward process that allows you to create new plants without having to purchase additional bulbs.

Dividing Clumps

One common method of propagating cannas is by dividing clumps. Over time, cannas tend to form dense clumps of rhizomes, which can become crowded and hinder the plant’s growth. Dividing these clumps not only helps to rejuvenate the plants but also provides an opportunity to propagate new ones.

To divide cannas, start by carefully lifting the clump from the ground using a garden fork or spade. Gently shake off any excess soil to expose the rhizomes. Rhizomes are thick, fleshy stems that store nutrients and energy for the plant. They are usually located just below the soil surface and are responsible for producing new shoots and roots.

Once the clump is exposed, inspect it for healthy rhizomes with visible buds or shoots. Avoid rhizomes that appear soft, moldy, or damaged, as they may not produce viable plants. Using a clean, sharp knife or garden shears, cut the clump into smaller sections, ensuring that each section has at least one healthy rhizome and a few shoots.

Before replanting the divided sections, it’s important to prepare the soil by incorporating organic matter such as compost or well-rotted manure. This will provide the newly divided cannas with the necessary nutrients and improve soil drainage. Plant each section at the recommended planting depth (link to bulb planting depth) and spacing, making sure that the bud or shoot is facing upwards.

Storing Bulbs for Next Season

If you wish to store cannas for the next growing season or want to save bulbs from the previous year, proper storage is crucial to ensure their survival. In regions where cannas are not winter hardy, storing bulbs is essential to protect them from frost and freezing temperatures.

To store cannas, start by digging up the bulbs after the first frost has killed the foliage. Carefully lift the bulbs from the ground, taking care not to damage them. Shake off any excess soil and trim the foliage down to a few inches above the bulb. This will help reduce the risk of rot during storage.

Next, gently brush off any remaining soil and allow the bulbs to air dry for a few days in a well-ventilated area. Once dry, store the bulbs in a cool, dry, and dark place, such as a basement or garage. It’s important to ensure that the storage location maintains a consistent temperature between 45°F (7°C) and 55°F (13°C).

To prevent the bulbs from drying out, you can pack them in a breathable material such as peat moss, vermiculite, or sawdust. Place the bulbs in a container or paper bag, and make sure they are not touching each other. Check the bulbs periodically throughout the storage period and remove any that show signs of rot or disease.

By following these propagation techniques, you can easily multiply your cannas and enjoy an even more stunning display of these magnificent plants in your garden. Whether you choose to divide clumps or store bulbs, propagating cannas allows you to share the beauty and joy of these captivating blooms with others.
