3 tips for planting a tricky slope PLUS 20 plants that will thrive on slopes


Lily of the Valley.

A little ingenuity and the right plants can help you overcome one of the biggest landscape challenges, the awkward slope.

Words: Jane Wrigglesworth

1. Go for low maintenance plants

It’s awkward and uncomfortable working on a slope, even one that’s not steep. Make it easier for yourself by selecting varieties that:
• are drought-tolerant;
• are self-seeding (and/or spreading);
• require little to no pruning or dead-heading.

2. Avoid planting invasive or extremely fast-growing plants

The initial growth spurt of fast-growing plants will fill a space quickly, but almost all require regular hacking to look tidy and can become a pest when they spread to other areas.

3. Time the blooms

Select plants that bloom at different times, so there’s always something colourful and interesting. If you like a particular plant, different varieties may be the answer. For example, thyme is the perfect low-growing evergreen perennial: drought tolerant, spreading, its bright-coloured flowers attract bees, and there’s a range of varieties that flower at different times of the year.

• ground covers are one of the best ways to beautify a slope and help prevent erosion;
• mass-planting is a good idea, but go for a variety of different plants – one plant en masse can look monotonous, and if a disease or pest hits it, there’s a higher chance of it wiping out the entire area, leaving it bare;
• mixed plantings also disguise small gaps or flaws in the slope.

To add interest:
• plant a couple of low-growing shrubs or trees;
• try clumps of spring-flowering bulbs, such as tulips and daffodils.
