Deore cassette with tiagra derailleur?

I recently bought a Surly cross check for commuting, light touring, and some road riding. I'd like to get some lower gear ratios going for the steep hills around where I live and for when I do load the bike. However, it looks like converting the bike to a triple will be sort of $$$ at the moment so I was going to try to simply change the cassette and see where that gets me. The rear deraileur that came with the bike is tiagra. Will that work with a 9 speed deore cassette or will I need to replace the rear derailleur as well? If anyone has any thoughts or other ideas, I would really appreciate it.

no, not really.

tiagra RD, maximum sprocket size is 29T, maybe 30T if you're lucky.
deore cassette only comes in 11-32, 11-34 and 12-34
Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)
