Food choice should shift with the seasons. High-fat foods such as fat balls and suet blocks suit the colder months, when birds need extra energy to maintain body heat. During the breeding season, softer foods and mealworms are more useful, since adult birds feed these to chicks that cannot yet manage tougher foods. Sunflower hearts work well year round and avoid the mess of husks left by whole sunflower seeds.

Design details matter more than they might appear to. Good insect houses combine hollow stems, such as bamboo or reed, bird feeders with drilled wood blocks offering a range of hole diameters, roughly 2 to 10mm, since different species use different sized cavities. Natural, untreated materials are preferable to anything varnished or chemically treated.

Feeding is straightforward but worth getting right. Meaty cat or dog food, or a specialist hedgehog food, is a better choice than bread and milk, which can cause digestive upset. A shallow dish of fresh water left out overnight is just as useful as food, particularly during dry spells in summer.

Different nematode species target different problems. Some are used against slugs, others against vine weevil grubs feeding on plant roots in containers and borders, and others against chafer grubs or leatherjackets damaging lawns. Because they are pest-specific, the right choice depends on identifying which pest is actually causing the damage.

Bees and other pollinating insects rely on gardens for a large share of their food, especially in built-up areas where wildflower meadows are scarce. A garden that offers flowers from early spring right through to autumn does far more for pollinators than one with a single showy burst of colour in June.

Stocking the pond with the right planting from the start makes a noticeable difference to how quickly it settles. A good place to begin is a considered selection of pond plants suited to the pond's size and depth.
