Plant Combinations for an Abundant Garden. A. & G. Bridgewater

paths are easy to lay

      Leading to a particular feature

      Curved paths are good for informal areas

      Crazy (cleft stone) paving is suitable for a relaxed garden

      Gravel and lavender are a good mix

      A simple crushed stone path is just right for this scented garden, and the edges are softened by the spread of the plants.

       PATH CONSTRUCTION

      Gravel A gravel path is a joy – it looks good and is relatively easy to install. Remove the turf and topsoil to a depth of 8 in (20 cm), and then put down a 4 in (10 cm) thick layer of compacted stone and gravel followed by a 4 in (10 cm) layer of pea gravel.

      Path construction – brick A red-brick path is a good traditional option. Remove the turf and topsoil down to a depth of 8 in (20 cm), and then put down 3 ½ in (8 cm) of compacted gravel, ⅞ in (20 mm) of compacted coarse sand and ¼ in (5 mm) of soft sand, followed by the bricks.

       STEPS IN THE GARDEN

      These attractive formal steps have been created with stone slabs forming the treads and bricks forming the risers.

      Informal steps made from reclaimed railroad ties are excellent for a country garden using natural materials.

      These brick and stone steps are adjoined by buttress hand supports, complete with lights for illuminating the steps after dark.

       DESIGNING AND PLANNING STEPS

       A functional feature

      If you have a sloping garden, you have the choice of scrambling about and just hoping that you do not slip, or you can build steps. Apart from being a good, practical solution, steps also function as a decorative feature that leads the eye from one level to another.

       Calculations

      Good, comfortable steps need to have risers at about 6–7 in (15–18 cm) high, with treads that measure 12–16 in (30–40 cm) from front to back.

       Construction and materials

      While there are lots of options – brick, stone, ties, wood, and many more beside – some materials are easier to use than others. For example, a mix of brick and stone is a good choice – the bricks are just right for the risers, and the stone can be sized to suit the depth of the treads.

      A flight of steps leading from a path up to a patio. To a great extent, the whole flight is supported on the concrete foundation that runs under the bottom step.

       STEP OPTIONS

      Log and gravel steps are a good option for a country garden, as they are quick to create.

      These corner steps in a path have been made from square paving slabs and bricks.

       PATH AND STEP PROBLEM-SOLVING

      Soft, sloping ground This flight of brick steps, with concrete over stone and gravel under every tread, is a good option for soft, damp ground. The extra- thick layer of stone and gravel and the pipe under the bottom step help to spread the load and drain off the water.

      Boggy ground A simple pole walkway is a good option for boggy ground. The poles are supported on posts or piles – the damper the ground, the longer the piles required. If you are worried about slipping, you could also include a handrail, as here.

      Existing concrete steps The best way of sorting out an ugly flight of concrete steps is to cover them with brick. All you do is leave the concrete in place and lay bricks over the treads. The remaining bits of concrete – the risers – can be stained or painted.

       PATH CONSTRUCTION

      For straight paths, use materials such as paving slabs and concrete pavers which will not need cutting and trimming. These are also best used on flat surfaces. Conversely, for a meandering path on sloping ground, choose crazy paving. Natural stone is also a possibility, but is more expensive. Because plants are often planted in the spaces between pieces of natural stone, do not use a spade to clear snow and ice away, nor put salt on the path.

       LAYING PAVING SLABS

      Pre-cast paving slabs are ideal for creating a firm, all-weather surface. They can be used on their own or combined with other materials, such as bricks, to create decorative patterns.

      1. Prepare the area of the path by removing topsoil and adding a 4 in (10 cm) thick layer of compacted filler.

      2. Spread and level a 2–3 in (5–7.5 cm) thick layer of coarse sand over the compacted filler.

      3. Mark on the sand the area of the first slab and place five blobs of mortar on it – one in each corner and one in the center.

      4. Carefully place a paving slab in position and check that it has a gentle slope so that surface water drains away.

      5. Position the next slab and check its slope. If the slabs have straight edges, place ½ in (12 mm) thick spaces between them.

      6. When the mortar is hard, remove the spaces and fill the joints with a stiff, dry, weak mortar mix (see below).

       When filling joints

      When filling gaps between paving slabs, take care that the mixture does not go on top of them, as it leaves marks. Instead, line the edges with masking tape; then use a stiff, dry, weak mortar mixture to fill the gaps. Tamp this level, to just below the surfaces of the slabs.

       Cutting paving slabs

      It is often necessary to cut paving slabs. Professionals use powered cutters (angle-grinders), but home gardeners can use a bolster (type of cold chisel) and a club hammer. Wear goggles and strong gloves and score a line on the slab (all edges and sides). Then, using the bolster and club
