Chives and chervil do well in small containers (assuming 3 inches of depth). “Chervil, especially, likes to be crowded,” says Shirey. Bonus if the cup is cracked, which allows for drainage. To avoid overwatering, let the plant sit with water in the saucer for 1 hour, then pour off the excess. “Overwatering kills more plants than underwatering,” says Shirey.
