Growing carrots is easy and it's something everyone can enjoy doing, even if it's just planting carrots in pots. And the flavour is the best.
In the olden days carrots were planted every spring, that's what everyone did. I used to know a small child who'd been scolded by her mother, again, for whingeing and refusing her serve of veggies. During an unsupervised moment she decided to put an end to the misery and make her parents proud at the same time. In order to be excused from eating veggies for at least a year, or listen to the nagging, she ate an entire row of finger sized carrots straight out of the ground. And then she couldn't understand why her parents were upset.
So remember to guard the carrots that you grow.
Starting: Sow seeds where they are to grow, as carrot seedlings don't like to be moved. Carrot seeds can take a few weeks to germinate. Eventually thin them to 5-7 cm apart. Keep the 'shoulders' covered to avoid green discolouration.
Soil: Light, sandy, well drained soil that hasn't been fertilized recently is ideal. Remove clumps and rocks to avoid getting crooked carrots.
Watering: Water evenly to avoid ending up with split roots.
Climate: They will grow in all climates.
Fertilizing: Carrots may not need much fertilizing. Too much will cause split or forked roots, as well as too many leaves and not enough roots. Kids will have fun growing carrot-men though.
Harvesting: Your seed packet will have the time expectation for your variety, but the best, tastiest small carrots can be harvested earlier. It's easier and less disruptive to pull the carrots from wet soil. Don't waste the tiny thinnings either, they're lovely and sweet in salads. If left too long in the ground carrots can become woody in the middle part.
Containers: There are baby cultivars and round varieties available. Also try regular carrots but harvest before they get too big. I once forgot about a pot with carrots, and by the time I pulled them up they had a 90 degree kink. Choose loam compost to grow your container carrots in.
Shady areas: They will grow slower in the shade, but I've had good results.
Pests and Diseases: Caterpillars occasionally attack the leaves. Slugs and snails can munch the roots and seedlings. Carrot fly has larvae which eat the roots, and they can ruin a crop. Rodents can be a problem.
