I think I am handling things properly so far. I would like to address the "why haven't you handled this seven years ago" crowd. YEAR ONE someone else owned the grapes. And I asked politely could something be done about this. The answer was silence and a shoulder shrug. YEAR TWO the new owner gave the same response. YEAR THREE I recommended that if he would not repair the rows all the way to the property line, over time the problem would be resolved. YEAR FOUR no change in his trespassing. But I find a riding stable that needs the field hay. YEAR FIVE the farmer sees the riding stable cut and windrow the grass and then comes in with his baler and hauls the hay to his farm. The riding stable calls me and says "they don't wish to fight over hay". YEAR SIX the farmer doesn't want the hay. YEAR SEVEN in April before any pruning is done I put up Posted signs. READ ORIGINAL POST.
Now Lets look at the situation as the year progresses. During pruning time that is when something can be done without damaging buds. Now the buds are out and fungicide spraying is taking place. Next he will be on the property to spray herbicides, a second fungicide spray and post pounding will take place as well as wire repair. During this time the vines are light weight and can be worked with fairly easily. By end of June And early July leaves are forming vines are lengthening and flowers are out. Vines are getting heavier. August Berries are forming. That's more weight. September Berries are getting plump and purple and we are starting to talk about tonnage weight on the trellis. October is Harvesting time with lots of tractors, rain and mud. November til Spring nothing gets done as we live in the snow belt with heavy lake affect snow off Lake Erie.
Finally I've tried to be reasonable, patient and logical but keep getting stubborn resistance. :confused3: And that is why some of the 20/20 hindsight comments have caused this post.

I expect that after the survey and my drainage ditch he will either ask for more time or just fill in the ditch. As for me, It would bother me to do this to a neighbor.

But I have given fair warning and despite his labors and cowardly temper tantrums, I will figure a way to stop this. :thumbsup:
