When to plant Salsify in Arid Australia

Arid zone — applies to Alice Springs, Mildura, Broken Hill, Kalgoorlie, Port Augusta and similar areas. Growing elsewhere? Temperate · Cool · Subtropical · Tropical.

Sow salsify direct from September to December, and again from January to March, working around the fiercest summer heat. This slow root crop resents transplanting, so seed goes straight into deep, stone-free soil at a 15-20 mm depth. Germination takes 10-18 days and the roots need a long 120-150 days to reach full size, so early-spring sowings in arid gardens like Mildura and Alice Springs give the best run before or after peak summer. Thin to 10-15 cm spacing in rows 30 cm apart. Deep, loose soil is essential for the long, straight tap-roots this oyster-flavoured vegetable is grown for.

Growing notes

Salsify rewards patience and deep soil more than anything else. The edible part is a long, slender tap-root, so the single biggest determinant of success is how deeply you have dug and how free of stones and clods the bed is. In the compacted, often stony soils around Broken Hill or Port Augusta, forked and stunted roots are the usual disappointment; the fix is to dig a bed a full spade-and-a-half deep and break up every clump before sowing.

Heat and dryness are the second challenge. Salsify sown too late runs into the peak of summer while still small, and moisture stress at that point makes roots woody and prone to bolting. Sow in early spring or wait until late summer for an autumn crop, mulch thickly, and never let the bed dry out fully during the long growing period.

Germinate reliably by keeping the seedbed evenly moist for the first three weeks; salsify seed is short-lived and patchy, so sow a little thicker than you think and thin later. Because it holds well in the ground, you can leave mature roots in the soil and lift them as needed through the cooler months rather than harvesting all at once. Any roots left to flower produce edible shoots and cheerful purple blooms.

Common questions

Why are my salsify roots forked and stunted?

Almost always stony or compacted soil. Salsify needs deep, loose, stone-free ground to form its long straight tap-root, so dig the bed a spade-and-a-half deep and remove clods before sowing. Fresh manure can also cause forking, so use well-rotted compost instead.

When is the best time to sow salsify in arid gardens?

Sow from September to December for a summer-autumn crop, or from January to March for an autumn harvest. Aim to keep the long 120-150 day growing period out of the very peak of summer heat where you can.

Can you leave salsify in the ground over winter?

Yes, and it is the best way to store it. Salsify holds well in the soil, so you can lift roots as needed through the cooler months rather than harvesting the whole row at once.

Why won't my salsify seed germinate?

Salsify seed is short-lived and germinates patchily, so always sow fresh seed and a little thicker than needed. Keep the seedbed evenly moist for the full three weeks it can take, as a bed that dries out will leave you with gaps.
