Harden off the seeds

Before you move your seedlings to their new homes, you need to gently expose them to the conditions outside. Start by putting the seeds outside for a few hours each day.  Over the course of a week, slowly increase the amount of time they spend outside.

Dig a hole

Dig a hole deep enough to hold the whole root ball of the plant in the prepared soil. To plant the baby, carefully take it out of its pot and put it in the hole. Make sure the top of the root ball is at the same level as the top of the dirt.

Water the seedling

Watering the seedlings right after replanting will help the soil settle and make sure the roots can get water.

Mulch the soil

Use straw, chopped leaves, or another organic material to cover the soil around the base of the plant. This will help keep water in the soil and keep weeds from growing.
