If you use pots there are factors to consider.
They dry out faster then plants in the ground so more watering time is required, (unless you use an automated system like the rain gutter type posted here in the past)
If you move the plants indoors for protection daily in the morning and again in the evening will use both time and energy that you might need for other purposes.
Moving them in and out could attract unwanted attention.
Damage to the plants is more likely then stationary plantings.
A large storage space will be required doubling the space needed for plants.
