Beware the wild violet
Even with decades of gardening experience I find that I still learn new things each year. I find that part of the fun of it. Learning for me often is a result of mistakes. A mistake I am just recognizing this Spring is my past passive tolerance of wild violets in the garden. In most of the garden which receives annuals, tillage occurs in the Spring and the Fall which is adequate to keep the violets under control. The small area devoted to perennials is another matter. Currently that consists only of asparagus and strawberries but formerly included a patch of ginger plants. I was aware of violets lurking among the ginger plants but did not perceive them as a problem. A couple of years ago I removed the ginger as it was not really serving any purpose. Violets there spread vigorously into the adjoining strawberry patch. Violets have rhizomes which spread readily and are not easily removed by hand weeding. They have now spread a distance of over 20' through the strawberries and are present thickly enough to provide some serious competition as well has making the berries harder to see for picking. The only solution I see is to propagate some this year's crop of strawberry daughters into a violet free area of the garden and then repeatedly till the current strawberry patch until violets are not longer appearing. I suspect this will take several years. The take away here is do not tolerate wild violets in your garden.
