What You'll Learn
Saffron crocus thrives in cool, temperate and arid regions in Australia
In Australia, saffron grows well in the Mount Lofty Ranges of South Australia, the Yarra Valley of Victoria, the alpine valleys of northeast Victoria, the western slopes of the Great Dividing Range in central New South Wales, and throughout most of Tasmania, except the west and parts of the northwest.
Saffron crocus grows best in a sunny position with well-drained soil. While the bulbs are actively growing, keep the soil moist; once dormant, allow the soil to dry out. Poor soil can be improved by adding organic matter before planting. For best results, plant in late summer when the saffron corms are dormant for flowering in late autumn.
Saffron crocus bulbs require a cold winter to flower successfully and will not grow in tropical or subtropical climates. A cool temperate climate is essential for saffron production. Mulch heavily in the summer months to protect the bulbs from hot temperatures. Weeds can be controlled with herbicides during summer or autumn, before the new season's growth of the crocus.

The best time to plant bulbs is late summer to early autumn
Saffron crocus bulbs should be planted in late summer to early autumn in Australia. In the southern hemisphere, saffron corms are available to buy during their dormant period, which is from December to April. In warmer and temperate climates, buckets of ice should be placed on the bulbs each night during winter to ensure sufficient winter chilling.
Saffron crocus grows best in cool, temperate and arid regions in Australia. It requires a cool Mediterranean climate, with hot, dry summers and cool to cold, wet winters. It is recommended to plant bulbs in full sun, or somewhere that will be sunny during the autumn flowering period. A sunny position is ideal, and the soil must be well-drained.
Planting at this time of year also allows the bulbs to benefit from the autumn and winter rainfall, which is important for their growth. Saffron crocus requires a cold winter with a few frosts to flower successfully. By planting in late summer to early autumn, the bulbs have enough time to develop strong roots before the cold weather arrives. This helps them to withstand the cold temperatures and increases their chances of surviving the winter and flowering in the spring.
In addition, planting saffron crocus bulbs in late summer to early autumn aligns with their natural growth cycle. Saffron crocus is a fall-blooming flower, and planting during this period allows the bulbs to develop and flower at the appropriate time. This timing also helps to avoid extreme temperatures, which can be detrimental to the growth of the bulbs. Late summer to early autumn provides a balance of warmth and moisture that is optimal for the healthy development of saffron crocus bulbs.

Saffron crocus requires well-drained soil and full sun
Saffron crocus is a beautiful bulb with purple flowers and three stigmas per flower. It is reasonably easy to grow, but there are some specific requirements to ensure success. One of the most important factors is well-drained soil. Saffron crocus will not thrive in waterlogged conditions, so it is crucial to choose a planting site with good drainage. While saffron crocus can grow in a range of soil types, from sandy to loamy, it is essential to ensure that the soil is not too compacted and allows for adequate drainage. Digging in organic matter, such as compost and well-rotted manure, can help improve soil drainage and fertility.
In addition to well-drained soil, saffron crocus requires full sun exposure. This means choosing a planting location that receives ample sunlight throughout the day. While the bulbs are actively growing, it is important to keep the soil moist. However, once the bulbs become dormant, typically in summer, allow the soil to dry out. The combination of full sun and well-drained soil helps the saffron crocus bulbs thrive and promotes healthy flower growth.
The ideal planting time for saffron crocus is late summer to early autumn, depending on the region. In warmer areas, such as Western Australia, autumn is the preferred planting season. When planting, place the bulbs 5 to 15 cm deep into the soil, with a recommended spacing of 15 cm between each bulb. Saffron crocus performs best in cool, temperate, and arid regions of Australia, such as Tasmania, western Victoria, elevated parts of South Australia, and western New South Wales.
To ensure the health of the saffron crocus corms, it is essential to maintain the right soil conditions. The soil pH should be slightly acidic to neutral, ideally around 6.5. Additionally, the soil fertility should not be too high, as saffron tends to perform better in less fertile soils. A cool temperate climate is crucial for successful saffron production. The natural climate for saffron crocus is a Mediterranean climate, characterised by cool to cold, wet winters and hot, dry summers.
By providing well-drained soil, full sun exposure, and the right climatic conditions, you can create an ideal environment for saffron crocus to thrive and produce its prized stigmas, which have been valued for their flavour, colour, and medicinal properties since ancient times.

The stigmas must be harvested straight after the flowers open
Saffron is the stigma, or female flower part, of the saffron crocus. Stigmas must be harvested straight after the flowers open because the flowers only appear for two to three days before shrivelling away. The harvesting process involves selecting open, upright flowers and gently pinching them without damaging the foliage or pulling the plant from the ground. This process is typically done by hand in the morning to ensure accuracy and a higher probability of the crocus reflowering in the season. The stigmas are then dried in a dry, sheltered spot for three to five days and stored in an airtight container.
The saffron crocus is a bulb with purple flowers, each containing three stigmas. It is a perennial bulb that grows up to 40 cm high and is summer dormant. It requires a cold winter with a few frosts to flower successfully. The best time to plant saffron crocus bulbs is during their dormant period in summer (December to April in the southern hemisphere) and in late summer to early autumn for the bulbs to flower in the following year.
In Australia, saffron grows well in cool, temperate, and arid regions with full sun and well-drained soil. It performs best on sites with sandy or loamy texture and slightly acidic to neutral pH levels. While saffron is relatively easy to grow, it requires long periods of sunlight and manual labour to pick the stigmas, making it the world's most expensive spice.
To harvest saffron stigmas, use your fingers or a pair of tweezers to gently pluck them from the centre of the flower. It takes about 50 to 60 saffron flowers to produce one tablespoon of saffron spice, and the stigmas should be dried in a cool, dark place before storing.

Dry stigmas should be stored in sealed glass jars
Once the saffron stigmas have been harvested and dried, it's important to store them properly to maintain their quality. Saffron is light-sensitive, so storing dry stigmas in glass jars helps protect the precious spice from degradation due to exposure to sunlight. Glass jars with airtight seals are ideal for creating a barrier against moisture and oxygen, both of which can affect the quality of the saffron over time.
The glass jars should be stored in a dark place, away from direct sunlight, to further protect the saffron from light degradation. Additionally, maintaining a consistent temperature in the storage area is crucial. Saffron is best stored in a cool, dry place, as heat and moisture can impact the spice's flavour and colour.
The use of glass jars also serves another purpose—safeguarding the saffron from pests. Insects, in particular, can be a nuisance, and glass jars provide a physical barrier to protect the stigmas. This is especially important given the high value of saffron, which makes it a tempting target for insects seeking a nutritious meal.
Finally, storing saffron in glass jars allows for easy identification and access. Saffron is known for its vibrant red colour, and storing it in glass jars makes it simple to identify and retrieve, ensuring a seamless cooking experience. Glass jars also provide a hygienic and sterile environment, which is crucial for a spice that comes into direct contact with food.
