This is contrasted to market gardening, where a variety of crops are grown on small farms for sale to local markets. Truck farms are larger, grow fewer types of crops, or only one type, and often grow seasonal crops.

Important truck crops include tomatoes, melons, onions, strawberries, citrus, potatoes, green vegetables and bananas.
