Growing Radicchio (source)

Radicchio, is similar to cabbage and mostly used as a salad green. It is red and white, slightly bitter and highly nutritious.

When to Plant

Radicchio is a perennial that will come back year after year once established in your garden. Radicchio thrives in cooler temps so try growing it during fall or early springtime.

If your radicchio plants are established, they can handle a little frost.   Remember, that radicchio doesn't do well in extreme heat, as it will cause it to go to seed.

How to Plant

Sow radicchio seeds very thinly, ¼ inch deep.  Sprinkle them over the loosely raked soil, and wait for germination to take place. Usually in just a few days. Radicchio also does well in containers as long as your pot is at least 8 inches deep.


How to Harvest

Harvest your radicchio right after the first few light frosts you have. It will help to remove some of the bitterness from the leaves.
