Actually growing carrots in a pot or container is a convenient way to produce your own fresh root vegetables, even if you don’t have the acreage for a full-fledged vegetable garden. One large round planter can yield up to thirty to forty carrots per harvest, depending on the weather, variety, and how many you’ve planted. Just find an area in your garden, patio, porch that can receive at least 6 or more hours of full sunlight. Even if it is cloudy, it will receive the UV light the carrots will need to grow sufficiently.
Your images aren't showing for me Justin. I agree about growing veggies in pots if you don't have the garden space. Some friends of ours grow them in window boxes.
I grow carrots in containers. I use perilite in the container soil along with an all purpose fertilizer. The temperature to direct sow depends on your last frost date. Farmers almanac has a chart for that. After I direct sow and thoroughly moisten the soil I keep the containers covered with a sheet and water as needed till they start to germinate. Carrots can handle a light frost and supposely get sweeter if they do get a frost.
I plan on growing carrots and radish in this next summer. I think I need to loosen the soil up a bit, seems sort of heavy this last fall.
