I am not sure it does nothing, David... I only use wood ashes to fertilize toms and Lemon trees in summer and they practically flop under the weight of the fruit. Sure it's not a teaspoon that does it, but you don't need massive amounts either.
I agree, Katherine....perhaps I did overstate my case. Whenever I've used wood ash as a potash source, it's been on open borders and I always thought an application rate of about 1/2lb per square yard to be about right. I will admit it is an excellent soil improver.

Are there any other good free sources of potash? I'm too tight to buy tomato feed. I read that coffee grounds might be OK?

Apols for not doing metric.
Will, I did devise a tomato fertilizer recipe using straight fertilizers many years ago that worked quite well & very economical.
Could post that recipe if you're interested.
Please do!
Okay, here we go:
2 parts by weight Sulphate of Ammonia
3 parts " Superphosphates
2 parts " Sulphate of Potash
Dose: one teaspoonful per plant every 7/10 days after first truss of flowers have set fruit.
Anyone else ever get the idea they're wasting their time????
