Saffron calendar

Crocus sativus prepares for eleven months of the year and flowers for a few weeks. Scroll to follow the year.

June — July

Summer dormancy

The leaves have dried. The corm rests in warm, dry soil and forms the flower of the coming autumn inside itself. No watering — it would break the sleep.

Soil
28–32°
Watering
none
August — early September

Planting

The corms are lifted, the largest are selected and replanted 12–15 cm deep. One field bears for 4–5 years.

Depth
12–15 cm
Spacing
10 cm
September

Awakening

With the first autumn rain the corm wakes: white roots go down, and a shoot in a white sheath goes up.

Soil
18–22°

October

Sprouting

The shoot breaks through the soil. Inside the sheath, a violet bud rises together with the leaves.

Night
8–10°
Bud
2–3 days
Late October — November

Flowering and harvest

The field turns violet. Each flower lives for one day — it is picked by hand at dawn, and its three red stigmas are separated and dried the same day.

Harvest
05:00–09:00

≈150 flowers
December — March

Winter leaves

The flowering is over; the work is not. Slender green leaves gather sunlight all winter and feed the daughter corms forming on top of the mother corm.

Leaf
30–40 cm
Frost hardiness
−15°
April — May

Corms maturing

The leaves yellow and lie down. All the strength passes into the new corms; the old one shrivels. The cycle closes.
