What kind of sprayer do you use?
I've been using the 2 gallon metal pump-up hand sprayers for years. I get about 2 years out of them before they need to be replaced. But my 20 trees are getting bigger and I'm tired of having to stop and refill so often.
A Northern Tool store opened nearby and I see that they have several different models of 12 volt sprayers. Do any of you use something like these?
