If I were to guess if after budding care is essential, then unstress your plants and help offset the investment in the 'plant slowdown' processes that toll the plant. So even though I had never thought of this before, but before and after -I do think watering in our summers will help the overall results quite a bit. 

I never knew that the tight bark budding problem can be fixed in such a short a time as 45 minutes, so I appreciate knowing about that.

I guess capturing water during rainy periods would offset the water costs. In which case I am not sure you know that any low cost 12 volt fuel pumps of the modern high-pressure fuel injection types from post 1985 cars would work well with a 12 volt photo-cell apparatus, a 12 volt battery etc. They last well with water and can shoot 20 feet across.

Thanks again John. But the link I am posting is what I read before I voted and the things I said in my first pararaph.
