Last week, I found out why my tomato harvest is so meager this year and why while the cucumbers started out very well, I did not harvest any lately. Rats! They also destroyed my watermelon patch. I had five beautiful melons growing and within a day and a half all of them were gone. The rat(s) had taken up residence under the wooden border of my plot and dug a little nest. I tried to flush them out with the garden hose and I thought it had done the trick. No fresh digging marks for a few days. Last night I discovered a newly dug hole. The obstacles of urban gardening, I suppose. But what a disappointment.
