4. The only way for growers to salvage frozen citrus is to process them quickly into juice concentrate before they rot when warmer weather returns.

5. Pronoun Questions
Sufficient.
To have it quickly processed into juice concentrate before warmer weather returns and rots the fruit - because citrus is singular and 'it' is the appropriate pronoun
