Gardener Job in Woodville, Ontario

We have an approx 1 acre property. Since fall 2015 we have been planting fruit and nut tree seedlings, started a large annual vegetable garden and planted various fruit bushes (raspberry, currants, blackberries, strawberries, blueberries etc)...most stuff gets destroyed by bugs, has stunted growth, bears little or no fruit. have tried avery thing under the sun to no avail - partners dream is to have this succeed but now so discouraged, says was giant waste of time $ effort etc. Need someone like yourself to tell us where we've gone wrong and how to fix all these trees plants etc so at least next year we can maybe look forward to seeing the bright side of our property again!
