Irene, I'm not sure I understand your question. The only real reason to have to dig tulip bulbs would be if you lived somewhere they didn't get enough cold and you had to provide that by refrigerating them for a time period. You certainly don't need to do that in North Carolina. Otherwise, tulips don't usually last more than a two or three years, and plenty of gardeners consider them as annuals, so it doesn't seem like it would be worth the effort to try to move them to another part of your garden. Let us know what you're trying to accomplish and we'll try to help.
Irene, in NC you plant tulips in the fall. If you want to find varieties that are more perennial check with www.BRENTANDBECKYSBULBS.COM the smaller species types of tulips are not as showy but will persist in the garden, including Tulipa clusiana.
Irene, most tulips are short-lived in our area of North Carolina. They get planted in the fall in an area that gets full sun and stay in the ground year-round. Fertilizing the bulbs when the foliage first appears in the winter may improve the chance of more than one year of bloom.It is best not to plant anything directly over the bulbs although some gardeners will try some shallow rooted annuals to provide some color in the summer. Most commercial landscapers in the area treat tulips as annuals; they dig the bulbs when they have finished blooming and discard the bulbs.
I was wanting to replant them somewhere else
Irene, if you want to move them somewhere and try to get another year out of them, wait until after they have bloomed and the foliage has yellowed, then dig them.
Now, that's good advice. Our "Darwins" were in the Chicago area. Plenty of cold weather to make them bloom in spring.
