In my experience, I have always watered bare root roses daily because the new roots are not sufficient to bring up enough moisture to the top growth. If you have purchased a boxed or packaged roses, this is even more important because the root mass has been cut back to fit the packaging and is often far too small to support the top growth.

I generally rehydrate my bare root roses over night in a bucket of water before planting, too.

If you have good drainage, it is hard to over water a newly planted bare root rose.
