We have been using Whitworth for about 3-4 years and they do a great job. So far we have only used their tree spraying service. Starting in the spring they come out and start a spraying rotation of all our fruit bearing trees. This keeps the bugs and diseases away and gives us tons of apples, pears, cherries, apricots & plums, They come out several times over the next few months to make sure the trees stay disease and pest free. It has been a great and pain free service.
