Azura

Family: Brassicaceae Vegetable

Azura kohlrabi brings a vivid, jewel-like sweetness to the garden—its bulbs swell into smooth, tender globes with a crisp, succulent bite.

Expect a fine, juicy texture that shines in fresh salads and slaws, and holds its character beautifully when roasted for caramelized edges. Grow Azura for a striking harvest at about 55 days, when the skins are at their most alluringly crisp and the flesh is at its most delicate.

Culinary Notes

Chef's Note

Azura’s kohlrabi is tuned for that clean, jewel-like sweetness with a crisp, watery bite—so eat it cold and thin first, before the heat coaxes it into caramel. Roast only until the edges bronze; it stays delicate and sweet rather than getting tough.

Best Uses

shaved raw in slaws that hold a snap under vinaigrette
quick-brined and served as a crunchy pickle-style side
roasted wedges for caramelized edges without turning woody
pan-seared slices with brown-butter or tahini sauce

Frequently Asked Questions

How do I manage powdery mildew on Azura during warm, humid spells?

Azura is prone to powdery mildew on leaves once conditions turn warm and humid. At the first sign of white, dusty patches, remove the worst affected leaves, then increase airflow by spacing plants and watering at the soil line (not over the foliage). Spray with a labeled sulfur-based or potassium bicarbonate fungicide and repeat according to the label every 5–7 days until new growth stays clean.

How often should I water Azura during the main growing phase (around weeks 2–6)?

During the main growth phase, keep the top 1 inch of soil consistently moist but not waterlogged—typically this means watering about 1–2 times per week depending on your soil and heat. Check by feel: if the top inch is dry, water thoroughly until it sinks in, but if it stays damp, wait. Avoid frequent light sprinkles that encourage shallow roots and leaf stress.

When is Azura ready to harvest at 55 days?

Harvest when plants reach full size and the crop shows its mature color/shape for Azura, typically around day 55 from sowing. Check daily during the final week—if it feels firm and looks fully developed with no overly small or pale sections, pick at peak size before quality declines. For best flavor, harvest in the morning and use promptly.
