Spring in Britain does not arrive all at once. A mild February morning will bring the first bumblebee shuffling out of the leaf litter, and by the middle of March the blackbirds are carrying nest material and the frogs have already returned to the pond. The garden that looked so dormant in January is quietly filling up with life, and the best thing you can do over the next few weeks is to work with it rather than against it.

Leave the Tidy-Up Until Late April

The single most useful change you can make this spring is to slow down. A neat garden is often a lifeless one, and the bits we instinctively want to clear away are exactly the places where wildlife is hiding.

Leaf litter, old seed heads, hollow stems and piles of dead wood provide shelter for beetles, ladybirds, queen bumblebees and the caterpillars that will feed next month's nestlings. If you cut everything back the moment the weather lifts, you evict hundreds of small creatures that took shelter there over winter.

Try a gentler approach:

• Cut herbaceous stems back in stages rather than all at once, leaving roughly 30cm standing for solitary bees to nest in.
• Leave the leaf litter under hedges and behind shrubs where it will not offend anyone.
• Keep one corner genuinely wild — a log pile, a patch of long grass, a stack of stones. It will look untidy for a fortnight and busy for the rest of the year.
• Hold back on the mower until you have had a few warm days and the ground has dried out.

Water Is the Quickest Wildlife Win

Nothing brings creatures into a garden faster than a reliable supply of clean water. Birds need it for drinking and bathing, hedgehogs need it after hibernation, and insects will gather at the edges of even a modest dish.

A bird bath should be shallow, with gently sloping sides and a stone or two placed inside so that a bathing blackbird can clamber out. Anything more than 5cm deep is a drowning risk for smaller birds. Scrub it out regularly with a stiff brush and plain water rather than reaching for chemicals, and refresh it every few days in warm spells to keep the water fresh and clear.

If you have a pond, keep the edges shallow and planted. Frogs, toads and newts all prefer gentle sloped sides to steep ones, and a strip of long grass or damp planting at the margin gives them somewhere to rest. In dry weather, top up ponds with rainwater from a butt rather than tap water, which carries nutrients that encourage algae.

Do remember to cover water butts or add a ramp inside. Every year, thousands of hedgehogs, frogs and birds drown after falling into an open butt they cannot climb out of.

Check Before You Cut: Hedges, Nests and the Law

All wild birds, their nests and their eggs are protected under the Wildlife and Countryside Act 1981. It is an offence to damage or destroy an active nest, and the nesting season runs roughly from March to August — sometimes later in a mild year.

Before you take a hedge trimmer to anything, do a slow lap of the garden and look for activity. Blackbirds, robins, dunnocks and wrens all nest low in hedges, ivy and dense climbers, often only a metre from the ground. Watch for a bird carrying material or food, or for a brooding bird sitting tight as you approach. If you find a nest, stop work in that area and come back in a few weeks. Hedges and shrubs that need a proper trim are best dealt with in late summer or early autumn.

The same care applies to the ground. Hedgehogs, frogs, slow worms and ground-nesting birds all use long grass, and a strimmer causes terrible injuries. Walk the area first, or start from the middle of a patch and work outwards so that anything hiding has a route to escape.

Welcome Back the Amphibians

Frogs usually return to garden ponds in February and March, laying clumps of spawn in the shallows. Toads follow a little later and leave their spawn in long strings, while smooth newts arrive quietly and lay eggs wrapped individually in pond weed.

Garden ponds have become genuinely important for British amphibians as so many wild ponds have been lost, so a few small habits are worth keeping:

• Never move spawn or froglets between ponds, as this spreads disease and non-native plants.
• Keep a third of the pond surface clear of vegetation and leave the rest planted up.
• Avoid fish if you want frogs and newts to thrive, as they eat the eggs and tadpoles.
• Leave a shallow, unfenced edge and some damp cover close by.

Food, Shelter and a Few Good Weeds

Put nest boxes up before the end of March if you can. Site them two to three metres up, facing between north and east, and out of the full afternoon sun. Clean out old boxes first and skip the pesticides anywhere near them, as nestlings eat enormous quantities of caterpillars and aphids.

With feeders, move away from whole peanuts and loose fats now that the weather is warming — they spoil quickly and whole peanuts can choke small chicks. Sunflower hearts, mealworms and quality seed mixes are safer. Wash feeders every couple of weeks with hot soapy water and let them dry fully, as dirty feeders spread disease through finch populations.

Finally, be a little forgiving with the lawn. Dandelions, daisies, primroses and violets are some of the earliest nectar sources of the year for queen bumblebees and butterflies. Let a patch flower, cut around it, and you will be feeding the very insects that will pollinate your beans, apples and tomatoes come summer.

Spring rewards patience more than effort. A few weeks of restraint now, a shallow dish of water and a second look before you start the hedge trimmer will turn your garden into the busiest, best-fed patch on the street.
