I used to really struggle with growing carrots, now they are one of our staple crops. Here’s what I do to make them grow more reliably:
• Plant them deeper than everyone says. I plant at around 3/4” deep. I use an earthway seeder, but you can just carefully sow them by hand if you don’t have one.
• Water them every day if it’s not raining until they come up. It can take up to 3 weeks sometimes.
• Around a week or two after they’re up, start thinning them so they are around 4” apart in the row. It’s important to be absolutely ruthless with this, if they are crowded then you won’t get more carrots, you’ll just get heaps of tiny things that are too small to eat.
• If weeds are taking over the bed, do some hoeing. I usually only need to weed once or twice early on.
• Mine take around 5 months to grow to a decent size. In my zone 8 or 9 climate, they can stay in the soil all winter without problems.
• Kuroda is my favourite variety, Koral has grown well here too.
