Making the Most of a Small Space

A courtyard of nine or ten square metres can still feel lush and generous if you stop thinking about floor space and start thinking about walls. Vertical gardening turns brickwork, fence panels, side returns and even the side of a shed into growing room. The trick is to work with the light you have and to build upwards in a way that is genuinely secure, because a loaded planter falling from height is more than a nuisance.

Before you drill anything, watch your courtyard for a day. Note where the sun lands at midday and how long it stays. Most fruiting vegetables and many flowering climbers want six hours or more, while ferns, ivies and hostas will cope with a north-facing wall that never sees direct sun.

Fixing Trellis and Supports to Walls

Solid brick and blockwork will take a screw and wall plug happily. Use a masonry bit matched to your plug size, drill a few millimetres deeper than the plug, and sink the fixing so the trellis sits at least 25mm off the wall. That air gap matters: it lets rain run behind, keeps the timber drier and gives climbers room to twine.

On older or crumbly mortar, aim for the brick rather than the joint, and consider a resin fixing for anything heavy. If you are fixing into a fence, screw into the rails rather than the feather-edge boards, and add a batten to spread the load.

• Tensioned wires are neat, cheap and almost invisible — run stainless wire between eye bolts at 40–45cm spacings for clematis and jasmine.
• Wooden trellis suits roses, sweet peas and annual climbers, and can be painted to blend with the wall.
• Metal grid panels take more weight and hold their shape for years.
• Check for pipes and cables before drilling, and never drill blind above a doorway or near a downpipe.

Hooks, Hanging Pots and Wall Baskets

Hooks are the quickest win. A row of galvanised screw hooks along a wall at about 1.8m will take hanging baskets, small trailing pots and even a lantern for evenings. Use a hook with a long thread for masonry and a shorter one for timber, and fit them into a batten if you want to spread the load across several fixings.

Choose your containers with weight in mind. Terracotta looks lovely, but a 30cm pot full of wet compost is heavy, so reserve it for sturdy brackets near ground level. Plastic, fibreglass and fabric grow bags weigh far less and dry out a little faster, so they pair well with a drip tray or self-watering reservoir.

Downpipes, drainpipes and gate posts are all fair game. Clip a bracket around an unused pipe and hang a small basket from it — it costs nothing, adds height and softens an awkward corner.

Troughs, Climbers and What to Grow

Wall-mounted troughs give you a proper root run in a shallow footprint. A trough 25–30cm deep and 20cm wide will happily host trailing nasturtiums, lobelia, ivy-leaved pelargoniums, strawberries or herbs such as thyme and oregano.

For height, climbers do the heavy lifting:

• Star jasmine and honeysuckle for scent, both happy in a sheltered courtyard.
• Clematis in groups two and three, which you can cut back hard each spring.
• Sweet peas for cut flowers and summer colour.
• Runner beans, cucumbers and cherry tomatoes if you want the space to earn its keep.

In a really tight spot, look for dwarf and patio varieties, which are bred to stay compact and crop heavily in small containers.

Compost, Watering and Feeding

Use a lightweight, peat-free multipurpose compost and lighten it further with a handful of perlite or vermiculite. Small containers dry out fast — often within a day in July — so water thoroughly each morning rather than little and often. Water until it runs from the drainage holes, then stop.

A few habits make a real difference:

• Mulch the surface with gravel or bark to slow evaporation.
• Group pots together so they shade one another.
• Move containers into the shade during heatwaves.
• Feed weekly with a liquid tomato feed once plants are flowering or fruiting.
• Fit a simple drip or capillary watering system if you are away often.

Keeping It Looking Good Through the Year

In autumn, cut back spent annuals, clear fallen leaves from troughs and check every fixing while the plants are bare. Replace tired compost in the top few centimetres and top up with fresh material. Tender plants in small pots are vulnerable to frost, so either wrap them or move them against a sheltered wall.

Come spring, prune your climbers, refresh the mulch and sow a few quick annuals to fill any gaps. Vertical gardens reward a little attention at the right moment, and a courtyard that looked like a plain yard in March can be thick with green by June.
