Why a single square metre is enough to test
A one-square-metre patch is small enough to dig, edge and replant in an afternoon, yet large enough to show whether a pollinator planting scheme is working. The useful test is not how many flowers appear in the first June but whether the patch supports insects across the season. A wildzy approach treats that square as a habitat unit: it needs sun, shelter, water and a succession of flowers, not just a packet of seed.
Read the site before buying plants
Most failures start with light and drainage. Spend ten minutes tracking sun at 10am, 1pm and 4pm; mark the patch’s sun hours on a sketch. Then dig a spade-depth hole and fill it with water. If it drains within an hour, the soil is free-draining; if it still holds water after three hours, choose moisture-tolerant species or add grit and raise the bed by 5–8 cm. These two facts decide whether lavender, foxgloves, sedges or asters will survive.
Build the patch in three layers
Use a simple layer plan: low nectar plants at the edge, mid-height flowers in the centre, and a woody or tall herb element on the sheltered side. For a sunny patch, combine thrift, wild marjoram and purple toadflax with a small rosemary or currant bush. For shade, use wood anemone, common dog-violet and a clump of foxglove. Keep 20–30 cm between groups so air moves; dense planting looks instant but collapses in damp winters. Leave one bare, sunny tile as a basking spot.
Maintain for insects, not tidiness
Cut back in late February or early March, not autumn; seed heads and hollow stems carry insects through winter. Remove cuttings to avoid enriching the soil, because rich soil favours coarse growth over wildflowers. Water only in the first six weeks and during prolonged dry spells; after that, deep roots should find moisture. Record the first bee, hoverfly or butterfly seen each month. If nothing visits by July, add a shallow water dish and move the tallest plant to the windward side.
Measure the result with a five-minute count
Once a week from April to September, stand still for five minutes and count insects landing on flowers. Note the group—bumblebee, solitary bee, hoverfly, butterfly—rather than trying to identify species. A healthy one-square-metre patch in a mild, sunny site should record at least three insect groups on most counts by midsummer. If it records one group only, add a second flower shape: umbellifers such as fennel, or tubular flowers such as honeysuckle. The count is the result that matters, because it turns a pretty border into a repeatable wildlife test.
