When can I sow chard in the UK?

April to July outdoors; March under cloches in southern England. A single April sowing usually crops continuously from June through to the following March or April when the plant bolts. Mid-summer sowings (July) crop from autumn through winter and into the following spring.

Is chard the same as Swiss chard or perpetual spinach?

Same species, all Beta vulgaris subsp. cicla. Swiss chard usually refers to the named cultivars with coloured stems (Bright Lights, Rhubarb chard, Fordhook Giant). Perpetual spinach is a green-stemmed type sold as a spinach alternative — same plant, marketed for the spinach-substitute angle. They're all the same family and grow the same way.

Why does chard not bolt like spinach?

Different species, despite the names. True spinach (Spinacia oleracea) is hard-wired to bolt as summer days lengthen. Chard (Beta vulgaris subsp. cicla) is a biennial — it grows in year one, bolts in year two. So a spring-sown chard gives leaf for 8–10 months before bolting, where spinach gives 4–6 weeks at best.

How long do chard plants last?

About 12–14 months — sown in April, they crop from June, through the winter, and bolt the following March or April. After bolting, replace with a fresh sowing. For continuous supply with no gap, sow a second batch in July; the older plants bolt as the new ones are coming online.

What's the difference between the coloured chards?

Mostly aesthetic. Bright Lights and Five Colours give a rainbow of white, yellow, orange, pink and red stems. Rhubarb chard has uniform deep red stems. Fordhook Giant has thick white stems and is the heaviest-cropping. Flavour differences are subtle; coloured stems tend to be slightly milder; white is more robust. Bright Lights wins on looks in an ornamental kitchen garden.

Can I grow chard in containers in the UK?

Excellent for containers. A 30 cm deep pot grows 3–4 plants. Use peat-free compost; water consistently; feed monthly through summer. The coloured cultivars (Bright Lights) make beautiful patio plants. Slug pressure is much lower in elevated containers than in the ground.

Burak liściowy / boćwina

Beta vulgaris Cicla Group

Nasiona boćwiny wysiewać bezpośrednio od kwietnia do lipca, w wilgotną, żyzną glebę, w pełnym słońcu lub w lekkim cieniu. Boćwina jest odporna na zimno (RHS H4–H5) i znacznie bardziej niezawodna w letnim uprawie liści w Wielkiej Brytanii niż szpinak — nie wybiega tak szybko i plonuje nieprzerwanie od czerwca aż do następnej wiosny przy niewielkiej ochronie zimowej. Odmiana Bright Lights daje łodygi w kolorze białym, żółtym, pomarańczowym i czerwonym; Fordhook Giant to standardowa odmiana o białych łodygach, dająca obfite plony; boćwina rabarbarowa ma ciemnoczerwone łodygi. Każde nasiono to skupisko 2–4 nasion — przerzedzić do jednego na każde miejsce w odległości 30 cm. Zewnętrzne łodygi i liście zbierać nieprzerwanie od 8 tygodni po wysiewie. Głównym szkodnikiem są ślimaki; poza tym jest to jedna z najłatwiejszych upraw w każdym brytyjskim ogrodzie przydomowym.
