Frost Damage on Tropical Annuals

Master Gardenerbrought in Crossandra leaves last week with neucrotic (dead) blotches and purpling leaf and inquired on pesticide damage.

Dave Robson Recommnedations were as follows:

It looks more like cold injury, Kelly, than chemical injury. Plant is more tropical in nature and since it's young tissue, probably got some frost injury on it. Chemical injury would probably be more distorted. Warm weather should stimulate new growth. These leaves may become holey where the tissue has died, but should be hidden by newer growth.

Kelly's Suggestions:

Remove some of the ugliest leaves and give a fertilizer treatment.
