Install a border of yellow perennials: step by step

Take inspiration from English gardens by creating this generous border of perennials, which will remain elegant for a long time and brighten up your summer.

Preperation

Install this bed preferably in spring, but you can proceed until the end of June, provided you ensure watering next summer. Start by carefully loosening the soil using a spade. Take the opportunity to add an organic fertilizer , such as compost or decomposed manure.

Purchase guide

Obtain grasses and perennials grown in pots. Opt for container-raised senna (cassia), which you’ll buy from a nurseryman specializing in exotic species.

Planting

Arrange the plants on the ground to judge the effect obtained. Moisturize the roots of senna well before planting it, then install grasses and perennials by digging holes with a dibble.

Maintenance

During the season, cut dead flowers and water as soon as the soil dries up. In the fall, protect senna and euryops or place them in a greenhouse for the winter . At the end of it, you will prune their twigs before taking them out in May, cut the dry stubble of the phalaris and the foliage of the lupine. In March, you will cut down the silver baskets and helichrysum and decompact the soil before spreading fertilizer and mulch.

Practical advice

Where to install it?

In a sunny position to prolong flowering and obtain colorful foliage, and in drained soil , because these plants prefer dry soil, without excess.

Completion time

2 to 3 hours for tillage and planting.

Cost

200 € for a 5 m² massif

Good to know

In cold regions, you will protect the senna, frost, either by wrapping the stump and the branches in a thick wintering veil, or by repotting it in October, after having pulled it up, to winter it under cover.

How to make this composition

Delimit a rectangular border of 1.20 m wide by 2 m long.

In the center and at the bottom of the massif, 60 cm from the edge, put the senna in place. Around it, 60 cm from its trunk, distribute the euryops. At the front of the massif, plant phalaris , lupine , helychrisum and silver baskets 25 cm from each other.

This last step can be reproduced and put end to end to create a circular mass.
