Radicchio can grow well in areas with mild climates throughout the winter months and can store well in the cooler for areas with harsher winters, making it a great option for winter sales. We offer a wide range of different types of late-maturing radicchio varieties.

Late season best practices

Choose late-maturing varieties for an extended harvest. These can be planted at the same time as fall-maturing varieties and will be ready for harvest over an extended period of time.
Later-maturing radicchio are more winter hardy and generally grow on larger frames.
It is best to harvest and store radicchio when it is at the optimal harvest point to prevent cracking and core elongation, which can occur in radicchio if left in the field to store.
Cold-hardy radicchio can withstand temperatures as low as 25° F. If temperatures fall below this for an extended period of time, it is recommended to cover radicchio with frost protection remay or harvest to store the radicchio in coolers.
When radicchio is stored in an ideal cooler climate, they can last 3-4 months and many times longer. There will just be some decomposed leaves on the outside that will need to be peeled back.
