Planting & Spacing Calculators

Correct plant spacing is one of the most important factors in creating a thriving garden, yet it is one of the easiest things to get wrong. Overcrowded plants compete for light, water, and nutrients, leading to poor growth and increased disease risk in the UK's damp maritime climate. Our plant spacing calculator takes the guesswork out of border planting by working out exactly how many plants you need for a given area, whether you are planting in rows, grids, or staggered patterns for a more natural look.

Hedging is a quintessentially British garden feature, with popular species like privet, beech, and laurel all requiring different spacing. The hedge spacing calculator covers single and double-row hedges — privet is typically planted at 3-5 plants per metre in a single row, while bare-root beech works best at 5 per metre in a staggered double row. For spring colour, the bulb planting calculator covers depths and spacings for UK favourites like daffodils (15cm deep, 10-15cm apart), tulips (15-20cm deep, 12cm apart), and crocuses (8cm deep, 8cm apart).

The UK allotment tradition has made vegetable spacing second nature to many gardeners, and tools like the row planting calculator and square foot gardening calculator bring that precision to every plot. For extending harvests through the growing season, the succession planting calculator spaces out your sowings at two to three week intervals from March through to August. The companion planting calculator helps pair crops that benefit each other — a practice increasingly popular as UK gardeners move towards more organic and sustainable growing methods.
