Alice must've put out the welcome mat in our garden.
The only vertebrate problem we've ever had are our 2 small dogs (the dachshund especially liked my tulip bed!), but a mean face and a good yelling at usually cured them of excavating and rolling in horse manure fertilizer. This year the problem looks like deep tunnels, approximately 2 inches in diameter, but I have yet to see what is making itself at home under my radish bed. I stuck a weeding tool to block one of the entry/exits but within a few hours another hole had been dug less than a foot away (and of course I was not there to see the culprit).
The welcome (or unwelcome) surprise this spring has been unusually warm temperatures. It jumped from 17°C to mid-20's in a day, and last week the highs were in the upper 20°C's at our altitude (700 m.s.l.). The lettuce took a beating, and so did the pea plants even if I have them in partial shade. All of the tomatoes, on the other hand, are in their environment with the heat and most of them are planted out. Corn, bittermelon, sweet melons, pole beans and sicilian serpent squash are going into the ground at the end of the month. If it continues to be hot like this I suppose harvest season will come sooner than we normally experience it.
