10 garden planting ideas for small gardens
Border planting ideas for small gardens often need to be different from those for larger gardens.
Beautiful herbaceous borders and drifts of plants look gorgeous in big gardens. But sometimes they are not practical in small ones. This is especially true if you have a narrow garden or a garden that’s an awkward shape.
So this is the first part of ’10 small garden border planting ideas’ that you can try instead. (The second part will be next week)
Garden designer Posy Gentles creates planting ideas for all or part of her clients’ gardens. These vary from larger country gardens to small town spaces. So she sees how different plants and plant combinations work in different sizes of garden.
Her own garden is long and thin. It’s around 20ft wide and 100ft long, so she tries out many of her planting ideas here.
Note: by ‘small garden’ I mean a typical town or village garden. It may be long and thin, square or even wedged-shaped. It could be the ‘average garden’, which is 50ft long.
Why planting ideas are different in a small garden
A ‘large garden’ in gardening terms can mean ten or fifteen acres, or even more. The great gardens inspire us. They are where new plants are developed and horticultural expertise is nurtured. Without the great gardens to lead the way, our own gardens would be very much poorer.
But most of us do not have a ‘large garden’. A garden of less than an acre may feel large if you’re trying to look after it without any professional help. Mine certainly does, which is why I call this blog ‘the Middlesized Garden.’ But in real gardening terms, my 100ft x 80ft town garden is ‘small’, as is Posy’s own garden.
And border planting ideas do not always work in the same way in small gardens as they do in big gardens. More space makes a big difference to some planting ideas. ‘For example, if I tried to plant a drift of anything in my garden, I’d use up all the planting space on just one type of plant, ‘says Posy.
She also thinks that a traditional herbaceous border with chunky shrubs and big blocks of colour are less likely to work in a small garden. ‘If you have airy planting, then the eye can rest on it, and then see through. Solid plants and shapes will make the garden feel smaller because you can’t see beyond them.’
Posy’s 10 planting ideas for smaller gardens
- Start with the evergreen structure – use evergreens as punctuation points
- Add vertical planting so the eye goes up
- Include plants for architectural shape
- Always have at least one tree
- Add layers – a gauze-like soft focus layer and a glitter layer with small points of colour from small flowers
- Use climbers to take the garden upwards and blur boundaries.
- Think about leaf colour and shape.
- Add light and contrast with variegated or glossy leaves
- Include plants with movement, such as grasses and bamboo
- Contrast with scale. Big leaves and big plants next to smaller ones
Start with evergreen structure
Posy advises you to think about using structural evergreen plants to anchor the garden. Think about how they will lead the eye.
‘If you want to lead the eye down the garden, alternate evergreen plants, placing them asymmetrically.
On the other hand, two plants opposite each other delineates a gateway. It can mark a boundary or a separate area in the garden.’
Posy also recommends grouping a collection of structural plants to make ‘an arrangement.’ ‘In small gardens, you don’t want planting that blocks off the garden, so a grouping of different sized evergreens will mark out a change of area better than something solid like a hedge.’
Vertical planting leads the eye upwards
‘Try to get as much vertical planting as possible in a small garden,’ advises Posy. ‘A large garden can have a big herbaceous border spread out in front of you, but that won’t fit into a small garden. Use the vertical space to add colour and shape.’
Foxgloves, sanguisorba and persicaria are all good plants for vertical interest.
Add architectural plants for a small garden
Posy combines ‘soft-focus’ planting in pastel colours – for example, pink Baby’s Breath and lilac Thalictrum – with plants that have a strong architectural shape. Plants with a strong shape can be planted singly – you don’t have to keep to the traditional planting advice to plant in threes or fives.
And vary the size of architectural plants. Posy’s top plants for architectural shape include small plants with a good shape such as ferns and curly kale as well as dramatic cardoons.
‘If you have lots of perennials or flowers without the punctuation of architectural plants, then it can look like a mess,’ says Posy.
Always have at least one tree in a small garden
‘Always have at least one tree in a small garden,’ advises Posy. ‘It leads the eye upwards and makes the most of your vertical space. You need to choose your tree carefully, and it will create shade. But there are lots of excellent planting ideas for shade. ‘
‘You could even have a small garden with a number of trees, and make shade gardening your focus,’ she suggests. ‘If you’re living in a town, you’re probably very over-looked so that would be very private.’
Layer small garden planting ideas with soft focus and ‘glitter’
When it comes to flowers and colour, Posy thinks that big blocks of strong colour can make a small garden feel smaller because they stop the eye. You can’t see beyond a traditional herbaceous border with clumps of plants.
Which is fine in a larger garden because you can walk on to explore. In a small or middle-sized garden, this could feel too solid and chunky. (although Posy also emphasises that ‘All rules are made to be broken’).
So she likes to think of adding colour in layers that you can see through or which don’t occupy much space.
For example, you can get ‘soft-focus’ interest by using plants that have a delicate lacy structure. These include fennel and nigella. They take up very little space but act like a gauze across other plants.
And she uses ‘glitter’ as a way of describing small dots of colour from small flowers. These are scattered across her borders, sprinkling colour and light without obscuring the view beyond.
Good plants for ‘glitter’ include astrantia, gypsophila and Saxifrage ‘London Pride.’
Posy also believes that flowers in soft colours and pastels work better than very bright or strong colours in a small garden because a lot of very bright flowers is like drawing a line around an area.
