Hopefully this isn't just me being dense.  
i have a photograph of a rock wall 

the image goes left to right. 
i want to blur half the wall

I select the blur tool and paint the area but nothing gets blurred. 
what am I doing wrong?

thanks

From what you have told us, the Blur tool might not be the best fit. The important thing is that you view the results at 100% zoom ratio.  The example below is a single pass at full strength showing before and after.

 

Try ussing one of the blur filters, like Gaussian blur.

If you need to blur a particular area, the Quick Mask can be a good choice for selecting it

Hit Q, paint in the area, and hit Q again to exit QM

 

A big advantage of using a filter blur rather than the blur tool, is that you can make the layer a Smart Object, and apply the blur nondestructively

I am missing something the gaussian blur tool for me is a white square where you have the image and the tool us just a small box

To achieve better results with the Blur Tool from the Toolbox, consider adjusting the Strength setting. You can find this option in the Options bar, located just below the menus. The Blur Tool acts like a brush, gradually building up the effect as you release the mouse button. When you start painting again, it will add to the existing effect. Admittedly, it may take some time to build up the desired effect.
