How to Create a Herbaceous Border - A Simple Guide for Scottish Gardens

If you’ve been thinking about redesigning your flower beds or looking for soft landscaping inspiration, a herbaceous border is a fantastic option. When planned properly, it provides colour, texture, and seasonal interest while remaining relatively low maintenance even in Scottish weather conditions.

Below is a simple step-by-step guide based on one of our recent projects.

Step 1: Plan Your Planting

Before any digging begins, take time to plan which plants you want and where they will go. As a general rule:

• Taller plants at the back

• Medium plants in the middle

• Low-growing plants at the front

For Scottish gardens, reliable herbaceous perennials include hardy geraniums, hostas, astrantia, alchemilla, persicaria, lupins, foxgloves and delphiniums. Spacing them out is essential as the plants should be close enough to knit together as they mature, but not overcrowd.

Step 2: Prepare the Ground

Once the layout is planned, thoroughly weed the area to reduce the competition for nutrients and prevent future maintenance headaches! We recommend improving the soil by adding fresh topsoil or compost, as this will freshen up the soil and add nutrients for the new plants. Healthy soil is the foundation of a successful border.

Step 3: Weed Control and Planting

To keep the area weed free for longer, we install a geotextile weed control membrane. Once laid:

• Cut openings where plants will go

• Plant through the membrane

• Leave roughly 1 foot of spacing between plants

Step 4: Finishing Touches

For a tidy finish and improved weed suppression we recommend topping the border with bark mulch - even if no membrane has been used. It creates a cleaner appearance, it retains moisture, and reduces weeds.
