Question about rose 'grades' and growing dormant rose
I just got a dormant rose plant that came in a bag. Its base is about 2" thick and it has about four stalks that are 9" high. One stalk is pretty thick. There are no leaves, and I don't see any hints of growth (no green buds or anything). I guess that's just because it's winter. Also, there's wax covering the stems.
My question is, should I plant it outside right now, or keep it in a pot indoors and plant it outside later?
Also, the label says it is "1.5 grade." Does this mean anything important? My guess is that it is not the highest grade. Does that make it harder to grow or something?
Thanks for any help!
