How long does radicchio take to mature?
Radicchio typically forms firm heads in about 60 to 80 days. Cool weather during head formation gives the best color and the classic crisp texture.
When is the best time to plant radicchio seeds?
Radicchio is best as a fall crop, sown in mid to late summer so heads mature in cool autumn weather. A spring sowing also works in mild climates but may bolt in heat.
Why is my radicchio bitter and how do I reduce it?
Radicchio is naturally bitter, and heat increases it. Cool weather and mature heads taste milder, and grilling or roasting also softens the bitterness.
How far apart should radicchio be spaced?
Space plants 8 to 12 inches apart in rows about 18 inches apart so each head has room to form tightly.
How do I harvest radicchio?
Cut the whole head at the base once it feels firm. In some cases a second smaller head will resprout from the stump if the weather stays cool.
How many seeds are in this radicchio packet?
