How to Grow Carrots in an Elevated Planter
Can you grow carrots in an elevated planter (read: not in the ground)? Yes, you can! Watch the video to see how we grew several different types of carrots in a 2′ x 8′ Elevated Cedar Planter Box from Gardener’s Supply Company.
Most varieties of carrots need room to grow (they can get over 12 inches long) and elevated planters are generally not deep enough. So the solution is to use specific kinds of carrots – here are some of my favorite shorter carrot varieties (links will take to you to where you can buy the seeds):

Danvers 126 Half Long from Baker Creek Heirloom Seeds

How to grow carrots in an elevated planter
Make sure you’re growing carrots during the right time of year, with the right potting mix, and using the right kind of carrots.
Use the right soil and seeds
Carrots tend to get pretty long, and they need loose soil with no sticks or rocks (or they’ll branch, bend, stop growing and/or stick out roots in all directions). An organic potting mix is preferable since you will hopefully be eating the fruits of your labor!
See above for the recommended kinds of carrots – we chose those that would have room to grow in an elevated planter, such as baby carrots, round carrots, and shorter ones such as Danvers Half Long or Short Stuff. Some of these would also be good options for growing in a container (provided that it’s at least 6 inches deep).
The potting mix needs to be moist, and it needs to stay consistently moist. Since carrot seeds are so small, you can buy pelleted seeds so that you can see them and spread them out better. Make sure that there is a thin, moist layer of potting mix over the seeds once they are sown.
Carrots grow best when they’re spaced about an inch or two apart, so either use seed tape when you sow them or thin them out as they grow.
The carrots listed here should take about 75-90 days to reach maturity – look at your seed packet to check specifics for the type that you grow.
If your round carrots are not round (like the one in the video), they’re probably not getting enough moisture, and they’re elongating to try to get more water.
Know your planting season
The elevated planter in this video is in Tucson, Arizona. The seeds were planted in October, and this video was shot in January, so they’re just about ready to be harvested. In other parts of the country (and world), this is not the ideal planting season for carrots. If you’re in a more northern climate, aim for early spring or early fall to plant in an elevated planter.
If you try to grow anything in an elevated planter in the south during the summer, the potting mix will dry out. Similarly, if you try to grow anything in an elevated planter during the winter months in the north, it will freeze.
