Carrots - only "winter vegs"?



Getting such good results with Asian carrot ""Kuroda" that I would
like to replant. But not waste time/space.

Is there a "rule" that says one can't plant this "winter veg" now?
I can see not planting spinach or lettuce, but...?

Mild Mediterranean climate. No really awful summer heat.

Input welcome from NG members with similar or near-similar micro-
climates.

TIA
