When to plant Snow Peas in Cool Australia

Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.

Snow peas have a shorter, sharper cool-zone window than shelling peas: sow direct from August to October, 20 mm deep, as winter loosens its grip. They are startlingly quick — germination in 7–14 days and flat, sweet pods in as little as 25–35 days from a well-timed sowing — which makes them the first real harvest of spring in gardens from Hobart to Armidale. Sow close, 8–10 cm apart against a trellis or mesh fence, and sow again three weeks later; a short succession stretches the picking across the whole spring.

Growing notes

The plants are frost hardy, so an August sowing in Canberra or Ballarat will germinate and grow through late frosts without complaint — but as with all peas, frost burns the flowers, and snow peas reach flowering fast. An early-August sowing in a frost-prone site can be blooming while hard frosts are still arriving; if your garden sits in a hollow, hold off until late August or September, or drape frost cloth over the row on clear, still nights. Later sowings into October crop quickly in the warming soil but finish sooner, because snow peas dislike real heat — in the cool zone the whole show is effectively over by early summer.

Position and soil are simple: full sun, free-draining ground that was fed for a previous crop, no added nitrogen, and a 1.5–2 m support installed at sowing, because even compact varieties sprawl. Keep water modest until emergence — seed rotting in cold, wet early-spring soil is the most frequent failure, and the fix is patience and drainage rather than more watering.

Pick pods flat and young, every day or two once they start. A snow pea left to fatten turns stringy and signals the vine to stop producing; picked hard, an August sowing plus a September follow-up keeps a family in stir-fries all spring.

Common questions

When should I plant snow peas in Hobart?

Sow direct from August to October. An August sowing gives the longest picking season, but in frost-prone spots wait until late August so flowering misses the hardest frosts.

How quickly do snow peas grow?

They are among the fastest crops in a cool-climate garden: seed emerges in 7–14 days and well-timed sowings produce pods in as little as 25–35 days.

Why aren't my snow pea flowers turning into pods?

Frost is the usual culprit — the plants are hardy but the flowers are not. Cover rows with frost cloth on clear, still nights, or delay sowing so flowering falls later in spring.

Do snow peas need a trellis?

Yes. Install a 1.5–2 m support at sowing time — even shorter varieties sprawl, and pods on trellised vines stay cleaner and are far easier to find and pick.
