When to Plant Radicchio in Baraga County, MI
What to do in May
May rewards gardeners who work with the weather, not against it. Here's how to stay in step this month in Baraga County, Michigan.
-
Transplant radicchio outside
Plant tomatoes deep — bury the stem up to the first true leaves to grow extra roots. Everything else goes in at the same depth it grew in the tray.
-
Put radicchio seeds straight in the ground
Mark the row. Birds and stray feet both have opinions about unmarked beds.

Radicchio Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
