Growing Info
Harvesting: For best flavor and texture, harvest carrots any time before, and until they reach their optimal size. Peak harvest period lasts about 3 weeks, longer in the fall. Late summer-sown carrots are sweetened after having been kissed by light frost; however, harvest before soil freezes, which may destroy the crop. In USDA zone 5 or warmer, carrots can be left in the ground for storage provided they are heavily mulched; harvest as needed on days the ground is not frozen.

This was my first time growing carrots and I think it will be a staple for me now. They turned out great unfortunately my soil has some stick and rocks so they didn’t turn out perfect but I’m happy with the results.

So far the fall garden has mostly sprouted and is growing fine both in pots/planters, raised beds and a small in-ground plot. Zone 8B but desert and elevation climate here. Scorching summer and cool to cold winter with nice spring and fall climate.

The red atomic carrots germinated beautifully and their tops grew very tall and sturdy. So far, so good.

Not loving these. They all came up faintly pink. They grew kind of wonky. Yet, my other carrots grew just fine. Not a soil issue. Will try these one more time and hope for a better result.
