Can I plant potted tulips in the ground, and if so, what is the best way to do it?

Yes, you can plant potted tulips in the ground. To do so, carefully remove the tulip plant from the pot, dig a hole in the ground that is slightly larger than the root ball, place the plant in the hole at the same depth it was in the pot, cover the roots with soil, and water thoroughly. Make sure to plant them in a location with well-draining soil and adequate sunlight for best results.
