Wall-side borders

It can be challenging to select plants for narrow borders next to walls or fences. Conditions may differ from those in other parts of the garden and plants chosen need to be smaller growing or more compact. However these situations can be sheltered and also create opportunities to grow a range of slightly more tender plants.

Introduction

Many gardens will have a planting spot at the base of a house wall, garage wall or fence. Often this is a long, narrow strip which may need more than just climbers to give it interest.

Since growing conditions – sun or shade, wet or dry – vary depending on the

aspect of the wall, choosing plants that best suit the site will offer most success.

Practical considerations

Borders at the base of walls can offer a number of challenges;

  • They may be drier than a more open bed due to the wall or fence casting a ‘rain shadow’
  • They often have shallow soil, rubble or restricted access due to cement footings, drains and path edges
  • They are usually narrow, limiting the use of broad or spreading plants, especially where they border a path required for access

To a limited extent, the border may be improved prior to planting by digging out loose rubble and replacing with topsoil. When adding soil next to a house wall, remember to keep it lower than the damp-proof course.

Most wall-side borders benefit from having organic matter dug in and can be mulched after planting with either more of the same (e.g. garden compost, leafmould or composted bark) or a more durable mulch of bark or gravel.

Suitable plants
