Rion, do you know what kind of rose it is? For eg, climbers and bush roses require very different pruning.
Whatever it is, I agree with John: they thrive on really heavy pruning.
Some old roses are really unfussy with soil and
water, but some of the more modern cultivars can be quite demanding ('modern' can be pretty old as far as roses are concerned...)
All roses that I know of need a fair amount of sun to bloom well.
In NZ, roses are generally underplanted with plants that look ok in the rose's 'off season', so you don't just have a bunch of sticks for half the year
