My front yard consists of five vegetable beds surrounded by gravel. There are no fences, and we do not want to put any in. Most years, my main wildlife problem is with deer that wander through and browse on many of the plants. Thus, I routinely spray deer repellent (this year, Liquid Fence).
Unfortunately, the repellent does not seem to keep the local fox family from digging in my beds. This year, two or three mornings in a row I awoke to new large holes, especially in my most sparsely planted bed. A number of transplants were lost. For now I have addressed the problem by filling the holes, planting more plants, putting some large rocks on top of the bed (it seems like their presence would make for less pleasant digging), and putting some old wire fencing over part of the bed. This seems to have deterred them for now, but I am interested in hearing about other ideas and experiences (preferably those that do not involve electronic gadgets).
