Can Carrots Be Container-Grown?

Containers

• Size matters when choosing the best container in which to plant carrots. Choose a container that is at least 12 inches wide and 12 inches deep, to allow for sufficient rooting. Drainage holes are also essential to growing carrots successfully in a container.

• To grow carrots in a container, use a lightweight potting medium for best results. The University of Arizona recommends using packaged potting soil that is readily available at garden centers. Its weight is better than a soilless mix, which does not offer enough support to plant roots. Soilless mixes also offer little nutrients needed for good plant growth. Lightweight soil and a lightweight container can result in damage for the plant.

Planting

• Container crops are planted at the same time as in an in-ground garden. Be sure to start with a clean container, and fill it to within one inch of the top with damp soil. Follow the manufacturer's instructions for sowing seeds or setting out the transplants. After planting, gently water the soil. Stake plants early in their development, if needed, to avoid root damage later.

General Care

• Carrots, and other plants, grown in containers are susceptible to drying out quickly. Frequently check the status of your soil, at least once a day, and water as needed. Apply water until it runs out of the drain holes. If containers rest on a hot, cement surface, consider raising them onto a pallet or other structure to allow for better air circulation. Move plants to a shady area during the hottest part of the day and protect them from severe weather conditions, like hail, wind storms or heavy rains.
