This Course Can Help You Choose and Use Plants in a Landscape There's more to landscaping than just plants, and this course has more to it than just plants; but plants are both a very big part of this course, and of being successful in landscaping! Take climbing plants for example. Climbers wonderful plants because they can perform many tasks, for example: they can waft scent throughout the garden or into the house through an open window; cool the house in summer; provide shade for outdoor living spaces; hide an ugly feature such as a fence or rubbish bin; clothe narrow walkways or do all of these tasks and also provide you with fruit! How to use climbers in a garden The most obvious use for climbers is to hide ugly views such as utility areas in the garden, or to create privacy from your neighbours or from the road. Climbers can be used to keep people, children and animals in (or out) of your garden or as windbreaks and noise barriers - although the latter will be minimal. Proving shade is another great use for climbers – you can create wonderful ambience in your outdoor living area with a pergola covered in a fruiting grapevine. Climbers can also define areas of your garden - separating one space of the garden from another into ‘garden rooms’. Breaking a garden up into a lot of small areas can create both interest, and make a garden seem a lot bigger than it really is. This is because a garden which can’t be seen all at once will always seem bigger than an open area - which you can take in with one glance. How do I grow them? Depending on the type of climber you want to grow and your garden, you may need to provide it with some growing support. First though it is useful to understand how the climber you want to grow, actually climbs - some need help! Climbers are usually one of three types: some like scrambling over other plants, building on their own stems for support and gradually growing higher and higher. Some like sweet peas or grape-vines are tendril bearers; the little tendrils wind themselves around anything and to encourage upward growth, a wire trellis is a great support for them. The third type is creepers which often form aerial support roots on the stem, sometimes these types also have small suction cups or sticky ends enabling them to stick firmly onto a flat support or wall; many climbers like ivies and climbing figs will cling to a wall, post, or anything else they touch. What sort of materials do I need? You can use materials such as trellis, wire mesh, single wires or nylon strings, it is best to avoid jute, as it will rot within a season and then you would need to keep retying the supports. Supports can be readily attached to a fence or wall or possibly the uprights or roof of a pergola, arbor or archway, or between two posts. Alternatively you may like to buy or build a purpose-made frame. Another tip for support that could work in your situation is to allow the climber to climb over rocks, tree stumps or logs; pelargoniums or geraniums are great plants for this purpose. You could also encourage climbers to grow through other plants, thereby extending the flowering season, or to add interest to an otherwise uninteresting plant - for example, clematis through a rose or a rose up a tree. Climbers that work well for this purpose are those that don’t attach themselves readily to a support (i.e. without sticky or twining tendrils). What are you looking for in a climber? Do you want a fast grower, a slow grower? Some climbers grow fast, others slow. Such as Chinese gooseberries and grape vines will live for decades, others such as nasturtiums, sweet peas and beans are annuals and die at the end of each year. Passionfruit have a medium longevity of around 3 years. Fast growers will provide shade or a screen quickly but also usually need more pruning and more often. Does it need to be evergreen or deciduous? Deciduous climbers such as a wisteria, grapes or roses are often used over a pergola - they will let in the winter sun, but exclude it in summer providing shade. For year round shade, popular plants are some of the Kennedia (native ornamental peas), evergreen jasmines, and evergreen clematis. Would you like an edible climbing screen of passionfruit or grapes? There are lots of climbing edible plants to choose from including Chinese gooseberry (kiwifruit), climbing beans, peas, choko, nasturtiums (flowers, seeds and leaves are all edible) even climbing tomatoes and climbing spinach (Malabar or Ceylon spinach)! Most edible plants such as these lower in late spring and summer. Perhaps you would like flowers of special themed colours, flowers for a particular time of the year, flowers for most of the year, just a foliage screen, maybe a perfumed climber or one for a tiny terrace or unit? There are hundreds of different climbers to choose from to suit any position and landscape need and for a wide range of soil types and climates.
