Setting aside part of your garden for "Wilding" or creating a wildlife garden gives another dimension to a garden. Over time, it will increase the wildlife visitors to your garden and the wild flowers. In my garden there is also a large wild area which, over several years, has been left to go wild.
Creating a wildlife area can be done slowly, just letting nature take over and seed what comes naturally. Some gardeners prefer to introduce specific plants and wildflowers. We can look at both, in my own garden it has been left to develop naturally, and it is amazing the range of wild flowers which appear, (as if from nowhere,) over the years. "Wilding" lets nature take its course, but you can be more creative and introduce wildflowers, tips, and advice about both below.
Whichever route you take, the type of wild flowers which appear, or which you introduce, need to be suited to your garden environment. The old rule "Right Plant, Right Place" applies just the same. If the wild area of your garden is damp, or boggy, Marsh Marigolds make take up residence naturally, or you may plant them, whereas a Corn Poppy will not and will not thrive if planted. Wildflowers, like any other plants, look for a garden which matches their natural growing environment.
