Unfortunately, you did not include your USDA zone. I am unable to say whether you will need to dig them up or not.
If you are anywhere within the US, you will not need to do so. They are hardy down to zone 2. If you are above zone 8, then you may need to offer summer protection, rather than winter protection.
