AS a general rule, a plant should be replanted at the same depth it was growing initially. This holds true whether you're transplanting zinnia seedling grown in a 6-pack, a shrub in a two gallon pot, or a tree that's been ball-and-burlapped.
Tomato plants are different. They have the ability to generate roots along their stems, which is why it's beneficial to plant them deeply. However, most plants do not produce roots from stem tissue. Burying a plant's stem will usually cause rot or even the death of the plant.
