Seed tape is beneficial in the garden for two reasons. The first benefit is seed tape helps those with limited mobility. Using seed tape to plant carrots or other tiny seeded plants means less bending and stooping. The second reason seed tape benefits gardeners is because little seeds often get scattered before hitting the soil. Seed tape keeps the carrot seeds or other small seeds right where you want them.
Till or spade the soil in the garden bed to a depth of at least 8 inches. A 12-inch wide row is sufficient for using carrot seed tape. Determine the length of the row by how many carrots you wish to plant. Till the garden bed two weeks before the last expected frost date. The deep tilling allows the carrots to develop properly in the soil. Remove any rocks or other debris. Break up large clumps of soil.
Add any compost or organic matter needed to the soil and work it into the soil. Create a straight row the desired length and form a trench 1/3 inch deep. Lay the seed tape into the trench. Cut off any excess.
Cover the carrot seed tape with 1/4 inch of soil. Water the carrot row being careful not to saturate the soil.
Continue watering the carrots on a weekly basis. Do not allow the soil to dry out or the seeds will die and not germinate.
Mulch the garden row where the carrot seed tape is planted with an organic mulch to keep down the weeds. The weeds rob the soil of needed nutrients that make the carrots thrive. Using an organic mulch will further enhance the garden soil for the next growing season. Avoid using hay or other seeded grass which may generate more weeds than necessary.
