The mixed-border which is none other than a vegetated garden border serves as much for separation as for decoration. Composed of perennials and annual plants, whether flowering or with decorative foliage, the mixed-border brings a touch of luxuriance and elegance to nature. Charly de Jardiland, our dedicated plant specialist, gives us some explanations to create an exceptional border.
Is mixed border a new trend in terms of exterior decoration?
If the term is still little known, the mixed-border is certainly used for ages by passionate gardeners. It is a border planted with various plants according to a logic to blend in with the decor. It meets the needs of plants but also an aesthetic concern. We can play the card of the single color or on the contrary recreate a painter's palette. However, a few rules must be observed to obtain a coherent mixed-border.
Can we mix all the plants in a mixed-border?
If one wishes not to disturb the plants which constitute a mixed-border, it is of course essential to take care of the needs of each of them. We therefore first pay attention to the soil in which they will be grown. For example, an acidic soil will welcome plants with heather soil such as azaleas, camellia or even hydrangea. On the other hand, many plants risk suffering from such an environment. We also grow plants together that have roughly the same water and light needs. And above all we make sure to choose our plants wisely so as to obtain a constant flowering, from the beginning to the end of the year.
Ideally, what can you plant for a mixed border of a wide variety?
By opting for a universal earth, the gardener who wishes to create an exuberant border can mix grasses, plants with decorative foliage, perennial plants and annual flowers. It is however preponderant to focus on perennials which generally represent two thirds of a mixed border. They bring the advantage of giving new flowers every year, unlike the annuals that will have to be replaced in the spring. It is just as important to create a rhythm by planting at regular intervals roses or giant canas for example. And be aware that you can give your border a romantic look, an English style or create a mixed border of scents. Nature allows you all the fantasies.
How to organize a mixed border for easy maintenance?
Whether it is a mixed-border on lawn or a mixed-border delimiting the terrace, we generally recommend a maximum width of 2.50 m. This dimension prevents the gardener from stepping on the ground to regularly cut faded flowers or hoe the soil at the foot of the plants. Of course, the lowest plants should be placed in front of the tallest so as not to be hidden. In the foreground, we therefore place the ground covers which serve to clearly delimit the border, prevent the proliferation of weeds and retain the soil from the border. Behind are planted medium-sized plants and in the background large plants such as the Delphinium.
How to obtain a very dense mixed-border?
The plantations are growing from year to year. The gardener must therefore know how to wait. But everyone knows that patience is one of the great qualities that any gardening enthusiast must demonstrate! However, if the first year the border is still fairly sparse, we can fill the spaces with biennial plants such as pansies, begonias, marigolds.
