Regrow Carrot Tops in Water

All you will need is a shallow bowl containing about an inch (2.5 cm) of water and a carrot top about one inch (2.5 cm) thick. Nestle the carrot top, including the greens, into the shallow water. Set the glass in a light but not sunny window and change the water daily. Roots and new leaf growth should appear in as few as three days.

After a few weeks, there should be enough root structure to transfer the carrot top to a container of potting soil where it can continue to grow.
