Vegetables which produce fruit, such as tomatoes, peppers, beans, etc., require at least six hours of full sun to be productive. Leaf and root vegetables can get by with fewer hours of direct sun. Flowers should also be selected according to the amount of sunlight they will receive. Small or low-growing flowers and vegetables are best for container gardening.
Herbs grow very well in containers and can be moved inside for winter to provide fresh seasonings.
Because container plants have root systems restricted by the container, culture and maintenance for these plants differ from that for plants in ground beds. Container plants must be fertilized and watered more often than garden plants. Water thoroughly to prevent the build up of soluble salts. In Nebraska, container-grown plants require regular watering. In hot weather when plants are growing rapidly, you may have to water more than once a day.
