Soil & Growing Conditions

Water: moist but well-drained or well-drained (RHS)

Soil pH range

5 8

Span reflects genuine variation between the cited authorities, not a single agreed figure.

Growth Stages

Stage	BBCH	Notes
Sowing	0	Sow seed 6mm deep in early spring; self-sows readily once established (RHS, Alibaba Gardening).
Rosette formation	1	Forms a rosette of toothed leaves, often overwintering (RHS).
Flowering	6	Tiny white flowers bloom spring through autumn on stems to 50cm (RHS).
Seed pod / harvest	8	Distinctive heart-shaped seed pods follow; harvest leaf rosettes at ~10cm for salads before flowering (RHS, PFAF).

Harvest & Storage

When to pick: Harvest rosettes at around 10cm height for salads, before flowering, for the mildest cress-like flavour; leaves also usable cooked (cabbage-like taste). Seeds can be ground for flavouring; root can be dug fresh or dried as a ginger substitute (PFAF).

Diseases

Albugo candida

RHS names this directly: may be susceptible to white blister.

What the research guides add

Shepherd’s purse is a common annual weed that is also edible, and NC State notes how hardy it is.

• A herbaceous annual in the mustard family that prefers moist, well-drained soil in full sun to partial shade; it tolerates drought, shade and soil compaction, and temperatures down to 10°F. (NC State Extension)
• Seeds germinate in spring and fall; each seedpod holds around 20 seeds, and the plant spreads by self-seeding. (NC State Extension)
• The leaves, seeds and flowering shoots are edible raw or cooked; young leaves are best added to salads before flowering. (NC State Extension)

   A secondary gardening reference rather than a university or horticultural authority, used only for edible-parts/harvest detail RHS's weed-advice page does not cover, not contradicted by it. Leaves, seeds and flowering shoots are edible, raw or cooked. Before flowering, young leaves can be added to salads; rosettes are best harvested at around 10cm height. Leaves and flowers taste cress-like raw or cabbage-like cooked. Seeds can be ground and used for flavouring in soups; fresh or dried root can substitute for ginger.
