Yes, Chantenay Red-Cored carrots can be scattered.
Prepare your soil for planting, then scatter your seeds evenly. Cover the seeds with soil covering them about 1/4”. As seeds begin to sprout, thin them out to allow enough space for the seeds to grow to maturity.

After sowing and watering the carrot seeds, place a board over the seeds until they start to germinate. The board makes sure the carrots stay in the soil and keeps in the moisture. Remove the board once the seeds have sprouted so the seedlings can receive light and continue to grow.

There are many reasons why Chantenay Red-Cored carrots can become deformed, the most common issues being the soil quality.
If the soil is too compact or clay-like, the carrots will have no room to grow and will become deformed. Rocks in the soil can act as an obstacle to carrot growth, and roots may bend and grow around them causing them to bend or fork.
Overcrowding can also cause carrot deformities. To prevent overcrowding, thin out seedlings and pull weeds as they grow. Carrots can become deformed or even stunted when overcrowded and competing for nutrients.

Though Chantenay Red-Cored carrots are harvested as annuals, they are actually biennial. To get them to go to seed, allow a few carrots to stay in the ground over the winter. Seed heads will begin to form in the spring, keep them on the plant until they dry. Separate the seeds by rubbing the seed heads in your hand. Store your seeds in a cool, dry location for planting in upcoming seasons.
