Push young plants or seedlings into a gap in paving or a wall rather than planting them in improved border soil, and leave them alone.

Care

Light

Full sun — essential for the long flowering season it is grown for.

Water

Low — once rooted in a wall or gravel it needs no watering at all.

Soil

Poor, sharply drained soil, gravel, or the mortar of a wall. It is happiest where there is almost no soil at all.

Pruning

Shear the whole plant over after the main flush to tidy it and bring on more flowers; cut it back hard in early spring to remove winter-damaged growth.

Feeding

No feeding. It flowers non-stop for months on nothing at all, and a fed plant makes lax green growth with far fewer daisies.

Propagation

Easiest from its own seedlings, which appear in paving joints and gravel and transplant well when small. Division in spring works too, and softwood cuttings root readily if you want a particular form.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.

Common problems

Self-seeding into paving

How to spot it. Seedlings in every crack and joint.

What to do. Usually a virtue rather than a fault; pull out the ones you don't want.

Winter losses on heavy soil

How to spot it. Plants rot over a wet winter in border soil.

What to do. Grow it in a wall, raised bed or gravel rather than in rich damp ground.

Straggly, sparse growth

How to spot it. Long lax stems and few flowers.

What to do. Shear it back hard; it regenerates quickly and flowers again.
