Why My Canna Lily Leaves Are Turning Brown
Certified GKH Gardening Expert
Canna lilies often develop brown edges when conditions are less humid than they are used to. Another reason may be salt burn. Salts in the water and in fertilizer can build up over time, accumulating along leaf edgesand causing leaf drying browning. It's important to water deeply and slowly. At least once a month, water deeply enough to "leach" or push salts well below the root zone. Also, if they are receiving too much direct sunlight, foliage can turn brown. Finally, canna leaves may turn yellow/brown as it enters dormancy.
