Here in the Vale of Doomed Attempts at Yardwork, we are suffering through 100 degree weather and also the aftereffects of a storm that knocked out power for a week and dumped tree limbs and other debris everywhere.  Now that we have (almost) finished cleaning up, we cannot help but notice that much of our lawn has died while we were cleaning up and that several of our trees look sick. (It's usually the sick trees that lose the limbs). So, once temperatures drop a bit I expect to be doing a lot of spraying to try and get things fixed up.  All our old hand sprayers have died or seized up. So this backpack sprayer will be a useful adjunct to the cheapo hose end sprayer that I also use.  The backpack sprayer should be less tiring than the hose end sprayer (no heavy hose to keep lugging around) and I should be less likely to get wet in the process.  Also, my hose end sprayer always dumps stuff in my face when I try to spray up into the trees. This sprayer should avoid that problem and should be able to spray higher into the trees.  If my results turn out not to meet my expectations I shall correct this review before September 1st.
