Canna 'Pink Sunburst' problems — and how to fix them
Canna 'Pink Sunburst' (Canna 'Pink Sunburst') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Foliage colour fade
Insufficient sun causes pink pigmentation to diminish. Ensure maximum sunlight exposure for the richest leaf colour.
Canna leaf roller
Larvae roll and eat leaves, especially young growth. Remove manually or spray with Bt.
Leaf scorch
Variegated tissue is more susceptible to browning at the leaf margins in hot, dry or windy conditions. Mulch and water consistently.
Aphids
Feed on new growth and can spread virus diseases. Control with insecticidal soap or neem oil.
