Trees, Shrubs & Small Gardens
Shrubs are permanent, versatile living parts of gardens and can be used in many ways. These include shrub and mixed borders, as hedges, windbreaks and focal points towards the end of a garden. They can also be used as specimen plants in lawns, shaped into topiary figures and planted in containers. Nowadays, few gardens are large enough to have a single-theme feature and invariably shrubs are either combined with border perennials in mixed borders or planted in small groups, alongside paths or in beds and corners. Small trees can also be selected as feature plants or to add a little height in compact spaces.
Shrubs and trees for small gardens are best selected for their small size or slow-growing nature.
Many of the plants mentioned below can be viewed on our Plant Finder.
QUALITIES TO LOOK FOR
Appearance: shrubs should have an attractive, natural appearance and not have to rely on being radically pruned each year – which seldom works. Some trees will provide year-round interest.
- Slow-growing: avoid shrubs and trees that grow rapidly and soon outgrow their allotted position. Such plants are a waste of money because they have to be removed within a year or two of planting.
- Diversity: where possible, select a shrub or tree that has several qualities, such as flowers and handsome leaves, or beautiful bark.
- Establishment: quick and easy establishment are essential, so always buy a healthy plant.
- Non-invasive: check that the plant is not invasive and will not soon dominate nearby plants or spread into neighbouring gardens.
BUYING HEALTHY PLANTS
Before buying or ordering a plant, check that it is suitable for your garden and will not, after a few years, become too large. It also needs to be right for your soil. Whether evergreen or deciduous, inspect it before buying. Such a check, however, is possible only with container-grown plants. For bare-rooted plants, and when buying through a catalogue, make sure the source is reputable and check that delivery dates are suitable.

TREES IN SMALL GARDENS
Trees give your garden structure, provide shade and make a wonderful resource for wildlife. No garden is too small for a tree, and there’s a wide and varied range of small flowering trees suitable for small spaces.
Choosing the appropriate varieties of ornamental trees for small gardens is crucial – some flowering cherries are much more suitable than others, for example. In addition to ornamental trees, edible and culinary apple trees can be grown in tight spaces: look for those grafted on to M27 rootstocks which will keep them small and encourage early fruiting. See below for some examples of trees suitable for small gardens:
