Yes, the gladiolus bulbs will need to be dug up in North Carolina. The bulbs can be stored during the winter months inside and replanted in the spring.
Gladiolus bulbs will not right themselves when planted upside down, as some bulbs do. They must be dug up and planted with the pointed end towards the top of the soil.

Yes.
As a perennial it can be left in the ground for between 5 and 10 years. Although clumps that become large, may be divided as and when necessary. Divide in early summer after the foliage has turned yellow. They can be put into onion sacks and stored in a cool place until ready for re planting
Dig up the bulb. Usually there are off shoot bulbs on it. Break that off and plant.
If the flower blooms in the Spring, the bulbs should be separated in the Fall. However, this does not need to be done every year. It is recommended that bulbs are dug up and separated every 3 or 4 years. If the bulbs are growing short or unevenly, it is time to dig up the bulbs and separate them.
You can if you want to, but it isn't necessary. It is better to either leave them, or dig and transplant in the autumn. If you do want to store the bulbs, pack them in damp peat moss in an airy mesh bag and keep in a cool place.
The best time to divide canna bulbs is in the fall. After the first frost, cut the stems down and dig up the tubers. Wash them and dust them with sulphur and put them away for the spring.

Tulips planted in appropriate conditions tend to multiply and divide, and can be dug up and separated at will. This can be done annually. Lily bulbs also multiply, and it is recommended that a gardener pro-actively dig up lily bulbs every two or three years, and plant the expanded inventory of bulbs in a different location.
A rhinoceros usually eats plants, leaves, little sticks and tree bark. It also uses it's horn to dig up roots, and bulbs.
Sometimes chipmunks (and squirrels) will dig up bulbs that are close to the surface, and then store them underground in a different location. If a chipmunk is scared off before it can store the bulbs, the bulbs are abandoned in random spots and take root. Tulips do not spread on their own, except in the sense that they form new bulbs each year (much like a garlic clove turns into a head of garlic).
