Why a Small Urban Garden Matters More Than You Think

There are around 270 species of bee in the UK, and the majority of them are solitary rather than social. They do not live in hives or produce honey; they nest in tiny holes, sandy patches and old mortar, and they forage alone. That is good news for anyone with a courtyard, a balcony or a modest back garden, because it means you do not need an orchard to be useful. Bees navigate by sight and scent, hopping from one flower-rich patch to the next. A well-planted small garden becomes a genuine refuelling station on a route that might otherwise be a long, hungry flight between parks.

The trick is not to cram in as many plants as possible, but to choose the right ones and to keep something in flower for as much of the year as you can manage. Bees need pollen and nectar from early spring, when queens emerge from hibernation, right through to late autumn, when the last generation needs to build up fat reserves. A gap in July or September is a real problem.

Choose Single Flowers, Not Doubles

This is the single most useful rule in bee-friendly gardening. A double flower has had its stamens and often its nectaries bred into extra petals, which looks lavish but leaves visiting insects with very little to eat. Single-flowered varieties keep their middles open and accessible.

• Dahlias: choose open, single varieties rather than pompom types, and leave them in the ground until the first frost.
• Roses: simple shrub roses and species roses are far more generous than tightly petalled modern hybrids.
• Cosmos, calendula and single geums: easy from seed and endlessly attractive to hoverflies as well as bees.
• Bedding plants: many petunias, begonias and busy Lizzies are bred for colour and offer almost nothing. Swap them for hardy annuals.

As a quick test, look straight down into the flower. If you can see the centre clearly, a bee can reach it too. If it looks like a ruffled pin cushion, walk on.

A Year of Bloom in a Few Square Metres

Sequence matters more than quantity. Aim for three or four reliable plants in flower at any one time.

• February to April: crocus, snowdrops, hellebores, pulmonaria (lungwort), flowering currant and wallflowers. These feed the first bumblebee queens when little else is open.
• May to June: comfrey, chives, alliums, catmint and thyme. Leave a patch of chives to flower rather than cutting every stem for the kitchen.
• July to August: lavender, borage, salvia, oregano, single dahlias and cosmos. Lavender in full sun on a warm afternoon is one of the busiest places in any British garden.
• September to November: sedum, asters, helenium, Japanese anemones and verbena. Ivy flowers late and is a superb autumn nectar source — think twice before cutting it all back.

Plant in generous clumps rather than single specimens. A bee will visit a solid patch of one flower repeatedly, wasting less energy than it would drifting between odd singles.

Water, Warmth and Somewhere to Nest

Bees get thirsty, and a pond is often unavailable in a small plot. A shallow dish set among the pots does the job perfectly. Put a few pebbles, marbles or corks in it so insects can land safely without drowning, top it up every day in hot weather, and site it in light shade so it does not evaporate by noon. A saucer from an old terracotta pot is ideal.

Shelter is just as important. A south or west-facing wall or fence stays warm and gives bees somewhere to bask on cool mornings. Beyond that, leave a little mess. A patch of bare, firm soil suits mining bees. Bundles of hollow stems, drilled blocks of untreated timber and a few rotting logs help solitary species. Resist the urge to tidy every fallen leaf in autumn; some bees overwinter in leaf litter and in the hollow bases of old plant stems, so leave those standing until April.

Small-Space Planting That Actually Works

• Use the biggest pots you can lift or fit. Small containers dry out fast and stress plants into a short flowering season.
• Group pots together to create a microclimate and a bigger target for passing bees.
• Grow herbs — thyme, oregano, sage, rosemary and mint — and let them flower. They are cheap, tough and superb forage.
• Sow hardy annuals in succession every three or four weeks from March to June for a longer, steadier supply.
• Skip pesticides entirely. Even products sold as bee-friendly can harm larvae, and the insects you spray are often the ones eating the pests.
• Use peat-free compost and mulch with homemade leaf mould or well-rotted manure to keep plants strong.

None of this requires a redesign. Add one shallow dish this weekend, swap one double flower for a single, and leave one patch of the garden a little wilder than the rest. Within a season you will hear the low hum that tells you the garden has become part of something larger.
