What are common canna bulb problems?
One of the most common diseases you’ll find on canna lilies is rust. The rust produces spores that move through the air or by water. The rust is powdery and red-brown in color. This disease is produced when conditions are humid and water is present on the foliage for a long period of time. Luckily, they aren’t picky so general-purpose fertilizers like 5-10-5 or 10-10-10 work just fine. A spring application is helpful for starting the plant off strong, and a couple mid-season applications are recommended to get the best bloom. For a great organic fertilizer, use fish emulsion as it is high in nitrogen.They flower from June to October. Canna lilies will only overwinter outside in a very sheltered garden in a mild area. To overwinter cannas in most parts of the country you will need somewhere frost free to store them in winter. Alternatively cover plants with a generous mulch and keep your fingers crossed.Cannas are hungry plants and will likely take all the fertilizer they can get.

What not to plant near lilies?
Choose low-growing companions: Do not plant tall plants next to your lilies, as they will shade the plants and reduce the production of Lily blooms. Underplanting your Lilies with a succession of flowers will reinforce the beauty of their spectacular blooms and extend the flowering season of your mixed border. Lilies look very nice when planted in groups of three to five bulbs. Space them about 12 inches apart so they have room to grow. Small lily bulb varieties should be planted two to four inches deep, and larger lily bulb varieties should be planted six inches deep.
