Although carrots like the sun, they prefer cooler temps, and can be planted up to a month before our average last freeze date, as long as the soil registers at least 45 degrees. Consider planting these starts in a 12" deep pot, carefully dividing each cell into two or three separate clumps and spacing them three inches apart. You'll need to thin each clump to the single strongest seedling, then sit back and be patient. If you want to harvest true baby carrots (and not big ones whittled down to look like baby carrots), start checking for root development by scratching gently around the base of the greens. Health tip: consider leaving your harvested carrots unpeeled, just scrub gently, as the red "skin" contains the most nutrients and unlike many store-bought carrots, are often not bitter. And by the way, don't be surprised if the inside of this Red carrot is yellow or orange!
