Create a perennial border

I have long wanted a perennial border in my garden. I would be happy to show you that this is possible even in the smallest area (my bed is only 2.50 m²). Let’s create a herbaceous bed together!

Prepare the new perennial border

So that the plants grow well later and the weeds do not take over, the first thing to do is to prepare the new herbaceous border. For this I dug out the bushes and the unsightly undergrowth including roots from the bed. A real feat! All weeds were carefully removed and a fresh layer of compost was applied. Work it in well and loosen the soil to the deep.

If you have major weed problems in your garden (e.g. girsch), it is advisable to additionally lay a weed fleece over the prepared herbaceous border.

The selection of perennials

The perfect harmony in the perennial border is not so difficult to achieve if you observe the following rules when choosing plants:

Choose a color palette similar to e.g. Red / orange tones, purple / blue tones or pink / white tones. At plants in Kölle, the perennials in the garden center are all sorted by color. This greatly simplifies the selection.
So that your perennial bed blooms from spring to autumn, and thus also a great source of food for the insects, you should pay attention to the different flowering times of the perennials. The flowering and maintenance calendar will help you with this.
Pick the perennials at different heights:
Tall or leading perennials (80cm – 1.20cm): phlox, delphinium, scented nettle, Indian nettle, verbena, tall grass, hollyhocks.
Medium-height perennials (60cm – 40cm): corkade flower
Low shrubs (20-40cm): cranesbill, lady’s mantle, pillow branches.
Important info: there are some perennials at different heights, e.g. Asters. Therefore, pay attention to the plant label when buying your plants. There is also important information about flowering and care. As a precaution, I keep the labels until I am familiar with my new perennials.

When buying and arranging the perennials in the bed, pay attention to the height information.

Place the perennials in the bed

Most of the perennials want to bed in spring or autumn. Then the selection in the garden center is also greatest. Before you place the plants directly in the bed, they are placed. The tall shrubs come to the rear and to the side, then the medium-high plants follow and the gaps are filled with the low shrubs. Make sure that the colors alternate. Form harmonious groups by e.g. a trio of low perennials. Take a lot of time to place the perennials and, if necessary, reposition the pots a few times until you have found the perfect place for each individual perennial.

Important: Note the planting distance that is stated on the label! Even if the young shrubs look very small and inconspicuous, this will change in just a few months. The perennials will not be quite as lush in the first two years, but later it can also be the case that you have to remove them again or reduce them by dividing them, as they take up too much space.

Perennial border in a cottage garden look

Not only perennials like delphiniums and hollyhocks, but also the wooden fences for a cottage garden look. By the way, 10-15 perennials are sufficient for a 2.50 sqm bed. My bed should bloom in light shades of blue and white. Hence my choice of the following plant: honorary price light blue, cranesbill blue and white, noble thistle blue, delphinium light blue, phlox white, ornamental sage purple and white, scented nettle purple, hollyhock white, coneflower white.
I put seeds of funnels and sweet peas directly on the chain fence – this reinforces the romantic flair of the cottage garden. The bed border made of shell limestone (it is best to always use materials that are native to your region) keeps the meadow away and gives the bed a visual hold and structure.

Planting the perennials

Before planting the perennials, be sure to water them well. This makes it much easier to remove them from your pot. With the spade, each planting hole is now excavated. This should be at least as deep as the pot in which the plant was bought.
So that the perennials can quickly “gain a foothold” in the new bed, it is advisable to loosen the root ball somewhat. Use your fingers to carefully break open the roots. The small injuries encourage the plant to grow new and healthy roots.

Pour well

So that the perennials grow well, they have to be watered properly after planting. To do this, remove the sprinkler from the watering can and pour it with a gentle water jet exactly at the root ball and not over the leaves. If the soil has settled afterwards, fill up again with fresh compost.
