Who this guide is for
- Homeowners planning beds along the front or sides of a house
- People refreshing dated or overgrown foundation planting
- Anyone framing an entrance with planting
- Gardeners balancing plant scale against a facade
Scale the planting to the house
Foundation planting should relate to the proportions of the facade: tall corners can anchor the ends, lower planting can run beneath windows, and the entrance can be framed without crowding. Mature size matters more than the size at planting.
Sketch the elevation and imagine plants at maturity so the band complements the house rather than swallowing it over time.
- Anchor corners with taller forms
- Keep planting low beneath windows
- Frame, don't crowd, the entrance
- Plan around mature size, not planting size
Setback and clearance from walls
Leaving space between plants and the wall is important so air can circulate, the facade stays accessible, and roots and foliage are not pressed against the building. A sensible setback also keeps planting clear of vents, meters and any below-grade features.
Where drainage, foundations or the building envelope are involved, route the assessment to a qualified professional, since clearances and conditions vary by property.
Drainage and ground conditions
The strip beside a house often has its own drainage character, and water shed from the roof can concentrate there. Planning planting that suits the conditions, and keeping beds from interfering with how water moves away from the house, protects both the plants and the building.
Any concerns about water sitting against the foundation should go to a qualified professional rather than being solved by planting alone.
- Note where roof runoff lands
- Avoid blocking drainage paths
- Choose plants suited to the conditions
- Defer water-against-wall concerns to a professional
Access and long-term maintenance
Leave room to reach windows, walls and services for cleaning and upkeep. Planting that seals access can make routine maintenance awkward and encourage neglect.
Choose a planting density and habit that you can realistically maintain, so the band stays tidy without constant intervention.

Frequently asked questions
Questions readers ask about this topic
How far from the wall should foundation planting sit?
Leave enough setback for air circulation, facade access and root and foliage room as plants mature, and keep clear of vents and meters. The right distance depends on plant size and the property, so plan to mature size and consult a professional where drainage or the envelope is involved.
Can foundation planting cause damp against the house?
Planting itself is not a substitute for proper drainage, and crowding plants against a wall can reduce airflow. If you have concerns about water sitting against the foundation, route that to a qualified professional rather than relying on plant choice alone.
What should go at the corners of the house?
Corners often suit taller, anchoring forms that frame the ends of the facade, with lower planting beneath windows. Plan around mature size so anchors hold their role without overwhelming the building over time.
How do I keep beds from blocking access?
Leave room to reach windows, walls and services for upkeep, and choose a density you can maintain. Planting that seals access tends to be neglected, so design the band with maintenance in mind from the start.
