Why Cool-Climate Gardens Matter for Bees

If you garden in a Scottish glen, on a Highland croft, or anywhere the growing season arrives late and leaves early, you already know that bees face a tougher bargain here than their cousins down south. Cold air rolling off the hills, driving rain, and thin, acidic soils all shorten the window when foraging is possible. Yet bumblebees in particular are remarkably hardy. The white-tailed bumblebee and the garden bumblebee will fly in drizzle and at temperatures that keep honeybees tucked away in the hive, and the moss carder bee is a genuine upland specialist. What these insects need from us is not exotic planting but reliable, generous supplies of nectar and pollen close to their nests, right through from early spring to the first hard frost.

The good news is that cool-climate gardening and pollinator-friendly gardening pull in the same direction. Plants that tolerate wind, wet roots and short summers are very often exactly the plants bees evolved alongside.

Start with Structure and Shelter

Before you buy a single packet of seed, look at how the wind moves through your plot. Bees expend a great deal of energy battling gusts, and a foraging trip that costs more calories than it earns is a trip wasted. A mixed hedge of native species — hawthorn, blackthorn, willow, rowan and wild cherry — does double duty, filtering the worst of the weather while offering blossom in succession. Even a modest windbreak of beech or a hazel hurdle will raise the temperature in the sheltered lea behind it by a degree or two, which matters more than you might think.

Leave a patch of rough ground. South-facing banks, old stone dykes and patches of bare, sandy earth are nesting habitat for many solitary bees and bumblebees. Resist the urge to tidy every corner; a small log pile or an unturned heap of soil at the foot of a wall is prime real estate.

• Plant a native hedge on the prevailing windward side.
• Keep a south-facing bank free of dense planting.
• Leave some bare ground and old stems standing over winter.

Hardy Flowers That Earn Their Place

The trick in a cool climate is to choose plants with single, open flowers. Doubled blooms may look handsome in a catalogue but often carry little or no accessible nectar, and bees cannot push past a forest of petals to reach it. Aim for a long sequence of flowering rather than one spectacular fortnight in July.

For early forage, when queens are emerging and hungry, nothing beats willow, pussy willow and hellebore, followed by pulmonaria, forget-me-not and comfrey. In the main season, foxgloves, cranesbill geraniums, catmint, lavender (choose a hardy English type in a sheltered spot), monarda, scabious and knapweed all perform well in a short summer. Late in the year, sedum, asters, Japanese anemone and ivy keep the larder open when queens need to build up fat reserves for winter.

• Favour single flowers over doubles every time.
• Plant in generous drifts — bees find clumps far more efficient than scattered singles.
• Include at least three plants flowering in each of spring, early summer, late summer and autumn.
• Let a few herbs bolt; flowering chives, thyme and marjoram are bee magnets.

Skip the Spray, Rethink the Tidy

This is the single most useful change any gardener can make. Broad-spectrum insecticides cannot tell a greenfly from a bumblebee, and even products marketed as "natural" or derived from plants can harm pollinators on contact or leave residues in nectar. In a short growing season, pest populations rarely build to the point where spraying is justified, and the predators you protect — ladybirds, hoverflies, lacewings and ground beetles — will do the work for you.

Accept some cosmetic damage. A little nibbling on a leaf or an aphid colony on the roses is the price of a living garden, and the birds will usually clear it within a fortnight. If you must intervene, a strong jet of water or a hand-squash is almost always enough.

Water, Soil and the Long Game

Cool, wet climates tend to produce leached, acidic soils, so a modest application of garden lime on brassicas and brassica-family flowers helps, but do not overdo it. Most bee-friendly perennials are unfussy about pH provided drainage is decent. Improve heavy ground with well-rotted compost rather than fresh manure, which can scorch roots and encourage rank growth at the expense of flowers.

Avoid the temptation to feed everything lavishly. Rich soil produces lush leaves and few blooms; leaner conditions push plants into flowering, which is precisely what pollinators want. On a wet site, raise beds or plant on a slight mound so crowns do not rot through winter.

• Mulch with compost in spring to hold moisture and suppress weeds.
• Water newly planted perennials through their first two summers.
• Divide overcrowded clumps every few years to keep them flowering freely.
• Leave seed heads standing — they feed birds and shelter overwintering insects.

A Garden That Works With the Glen

The pleasure of gardening in a cool, changeable place is that the landscape does half the work for you. Native hedgerows, wildflower verges and the moorland beyond your gate are all reservoirs of pollinators waiting to move in. Give them a sheltered, chemical-free, flower-rich patch with somewhere to nest, and they will find it. You will not need to coax them. You only need to stop making their lives difficult and let the glen do what it has always done.
