How To Build A Pergola
North or South, cool-loving annuals are often a fine choice for the parts of your garden where shade prevails. The shelter of a fence, pergola (a type of arbor see Chapter 12), porch, or overhanging tree keeps the plants cooler, preserving their flower color, prolonging bloom time, and protecting the plants from drying out in the hot sunshine.
These are some of the most spectacular and welt-known of ail climbers, producing a stunning display of large (lowers during summer They are derived from several forms such as florida, Jackmanii. lanuginosa, patens texensis and viticetla. They are superb for training over pergolas, irellises or along wires lensioneo against a wall Most are single lorms, but a few have double flowers. They include a wide range of colours, among which blue, mauve and purple can be found in the following types1 Alice Fisk' mauve), Barbara Dibley' pansy-violet, with a carmine stripe).

Proper pruning during the establishment years is necessary to establish a well-formed permanent framework for the vine. Developing or training young kiwifruit vines into a bilateral cordon allows for easier management when the plants are mature. Kiwifruit produce a crop on shoots that grow from 1-year-old canes (last year's growth). In the first few years, you train vines the same way for both the pergola and the T-bar system.
This spectacular Mexican hall-hardy perennial climber is best grown as a hail-hardy annual Fast-growing, ids ideal lor Ireliiswork and pergolas, displaying mid to dark green leaves lormed ol Ihree pairs of leaflets, and 6 5-7-5cm (2&-3tn) long, bell-shaped purple flowers with green, saucer-like calyces (outer protective pads) from early to late summer In a greenhouse it soon reaches 6m (20ft) but it does not grow so tali outdoors.
If sparkling tinsel highlights Christmas trees, then the garden I equivalent (or a trellis or pergola must be clematis, an extensive and varied group of climbers with flowers in many colours, including blue, mauve and purple It is usually the large-flowered forms that are grown and one of the best is Clematis x ackmann with violet-purple flowers from mid-summer to autumn This is especially attractive when grown with Rosa Mermaid' which has a rambling growth habit and large, single, sulphur-yellow flowers with deep amber stamens. Alternatively, this clematis looks splendid trained on a south-facing wall with a deep pink hydrangea at its base to create extra colour and provide a cool area of soil beneath for the rools of the clematis.
However, a T-bar system has yielded well at the NWREC, is easier to prune, and may be better suited for small-scale production. For a T-bar trellis, vines commonly are planted 15 feet apart in rows 15 feet apart, resulting in 194 plants per acre. With a ratio of 1 male 8 females, there are 174 female vines per acre. For the pergola, you may want to space rows 15 to 20 feet apart (see Trellis ).
Two main types of support structures or trellises are used in commercial kiwifruit production the T-bar and the pergola. A pergola provides a single plane of canopy about 6 feet above the ground. The T-bar trellis system consists of posts in rows with a cross arm at 6 feet high. T-bars are less expensive to construct, less labor-intensive to manage, and better suited to bee pollination. However, pergolas may produce more yield per acre, and the fruit are less susceptible to wind damage. Also, once the full canopy is established in a pergola, the shade reduces weed growth.
