Overwintering rhubarb - quick question

Hoping for a speedy response to my question because I'm going away tomorrow for a month.
I've covered all my raised beds but I don't know what to do with my rhubarb plant. It still has a few straggly stems and leaves.
Can I leave it until I return at the end of October - or do I need to do something to protect it?
I live in a mild corner of Ireland where freezing temperatures are rare and it's highly unlikely there'll be any frost while I'm away.
Any swift advise gratefully received as I need to deal with this today. (Yes, I know - should have been checking this weeks ago!)

Thanks, BumbleJo - that's exactly the answer I was hoping for. One less chore to deal with is great, considering I haven't even started packing yet.

Rhubarb originates from Siberia. As such it needs no protection whatever so don't worry.
