Cottage gardening is a very popular both in England and the US. The mix of low-care perennials, culinary herbs and annuals combined a natural, informal style, is for many, nostalgic of their grandmother or mother's gardens. Not only is the cottage garden a paradise for songbirds and pollinators (hummingbirds, bees and butterflies) with its diverse mix of flowers, but it's also an excellent source for cut flower bouquets for the house and spices for cooking.
I feel It's important to design an informal layout of curving paths around which the garden is created. Some design ideas to make the cottage garden more livable include:
A bench - Provides a welcome retreat among the flowers for the gardener.
A birdbath - Nothing is better than water for attracting birds.
Small growing flowering trees for light shade and fragrant spring flowers.
Crushed gravel paths - gravel keeps down the mud and creates an excellent environment for planting the edges of the path with colorful perennial groundcovers.
A not-too-tall fence or wall that encloses the cottage garden - this helps to create a more intimate setting and provide support for flowering vines and climbing roses.
Enrich the Soil and Use Regionally Suitable Plants
As with any garden, a healthy living soil is the garden's foundation in which a wide variety of plant species will thrive. Prepare the soil with a mix of high-quality compost and Yum Yum Mix fertilizer at recommended rates to ensure that the drainage is adequate and that the soil is fertile. The right mix of regionally suitable plants is the other crucial part of the equation. Chose plants that are adapted to your region's climate, soil and precipitation. This is an essential consideration, as for example, the cottage garden plant palette used in England or New England will be different from what grows best in the Great Plains or the Intermountain West. There is some overlap, but a "one size fits all" approach to plant selection doesn't apply to such a huge continent like North America.
Go Tall, Medium and Short
Planting too many tight, low mounding growers is counter to the look we try to achieve. Using flowers that re-seed themselves are also a plus in the cottage garden. Over time, this will give the garden a more natural, spontaneous look and help to populate the garden with more plants. It's the gardener's job to do some "editing" as the re-seeders spread so to maintain space for the other long-lived plants that stay put.
As for plant placement, the cottage garden needs a good mix of small, medium and tall plants to be scattered throughout the garden. Tall growers should be scattered in the middle and back of the beds. These tall growers help to emphasize a more informal feel and help create the look of barely controlled abundance.
