Climbing plants for walls and fences

Vertical greenery in your garden

Walls and fences take up space but rarely give anything back. With climbing plants you turn those bare surfaces into living green features. They bring colour, attract butterflies and bees, and even provide a touch of insulation against heat and cold. In a small garden where every square metre counts, vertical planting is the smartest move. Garden centres carry climbers for every situation.

Self-clinging climbers

Some climbers attach themselves to the wall without help:

Hedera helix (ivy) is the best-known self-clinger. Evergreen, shade-tolerant and virtually indestructible. Perfect for north-facing walls where little else grows. Note: ivy can damage pointing on weak masonry.

Parthenocissus tricuspidata (Boston ivy) clings with suction pads and turns spectacular red in autumn. Deciduous. Grows fast and covers large areas.

Hydrangea petiolaris (climbing hydrangea) is a stunning shade climber with white lacecap flowers in June. Slow in the first years but vigorous thereafter. Self-clinging on rough walls.

Climbers needing support

Other climbers require a trellis, wires or frame:

Clematis is the queen of climbers. Hundreds of varieties flowering from March to October. 'Montana' for large areas, 'Nelly Moser' for big blooms, 'Viticella' types for rich late-summer colour. Plant the base in shade, the top in sun.

Wisteria delivers a breathtaking spectacle with hanging trusses of purple or white flowers in May. It becomes very heavy and needs a sturdy frame. Prune twice a year for optimum flowering.

Lonicera (honeysuckle) fills summer evenings with fragrance and attracts moths. Semi-evergreen and fast-growing. Ideal for a romantic feel.

Choosing the right spot

South-facing walls are warm and dry. Choose clematis, passion flower or grape. North-facing walls are cool and shady: ivy, climbing hydrangea or some clematis (montana) thrive here. East and west walls offer a middle ground with mixed light.

Check whether the wall or fence can bear the weight. A mature wisteria weighs hundreds of kilograms. On a wooden fence, choose lighter species like clematis or annual climbers.

Installing a support system

Fix climbing wires or trellis with 5 to 10 centimetres of space between the wall and the support. That air gap prevents mould. Use stainless steel wires and vine eyes firmly anchored in the wall.

Run wires horizontally 30 to 45 centimetres apart. Guide young shoots by tying them gently with soft plant ties. Never with wire, as it cuts into stems.

Planting and care

Plant climbers 30 centimetres from the wall. Right against the wall the soil is often too dry. Dig a generous hole, work in compost and water well after planting. Guide the first shoots towards the support and tie them loosely.

Mulch around the base to retain moisture. Feed in spring with an organic fertiliser. Pruning varies by species: clematis falls into three pruning groups, wisteria needs summer and winter pruning, ivy gets one trim in spring.

Annual climbers

Want fast results without a long-term commitment? Annual climbers grow metres high in a single season:

Ipomoea (morning glory) flowers profusely in blue or purple. Cobaea scandens (cup and saucer vine) reaches metres with purple bells. Tropaeolum (nasturtium) delivers edible flowers in warm orange and yellow.

Sow indoors in April and plant out after the last frost.
