There are many diff carrots. I just read a pack that said plant early in dry soil.....even in Cali, not much dry soil in Jan/Feb.... I used carrot tape for the first time last year, it worked great, earlier attempts failed to grow anything from seeds, but these grew fast......the gophers loved them....Haha. I thought it was strange too since I have two packets of carrots and one said to plant Feb-March but the other says to plant in fall? I've never planted carrots before, so we'll have to see how they do.
