Sesame seeds are one of the oldest recorded oilseed crops, cultivated for their edible seeds and revered for their medicinal and nutritional properties. Sesame seeds are a staple in many diets and have a range of culinary uses, from the kitchen to the cocktail bar. Sesame seeds are well-suited to Australia's hot and dry conditions, and the global sesame seed market is projected to reach $26 billion by 2025, making the Australian sesame industry a high-growth potential emerging industry. This article will provide a step-by-step guide on how to grow sesame seeds in Australia, covering topics such as climate, soil, watering, and harvesting.

What You'll Learn
Sesame seeds are suited to Australia's hot and dry climate
Sesame seeds are well-suited to Australia's hot and dry climate. Sesame is a tropical annual herb that grows to about 60 cm tall, although some sources state it can grow up to 1.5 m. It is drought-tolerant and thrives in high temperatures with little water. Sesame is commercially produced in desert settings, so when we say it's drought-tolerant, we really mean it. Sesame prefers areas with a long, hot summer.
Sesame seeds can be planted directly into rows in the ground in late spring, at least one full month after any danger of frost has passed. The optimal soil temperature for germination is 21°C, and germination takes 10-14 days. Once the first true leaves form, the seeds can be transplanted into the ground or a larger container. If growing in a raised bed or the ground, space the plants 60 cm apart. Sesame likes full sun, so choose a spot in the garden with plenty of sunshine and well-drained soil.
Once established, sesame plants require little care. They can be watered once a week until transplant time. To increase productivity, try transplanting into a raised bed or using black plastic mulch over the soil. Avoid drip irrigation as sesame plants prefer dry conditions. Sesame is indeterminate, so it will continue to bloom and set seed capsules until the end of summer. Expect flowering to peak in mid-to-late summer.

Sow seeds in late spring/early summer
Sesame is a tropical annual herb that grows well in Australia's hot and dry conditions. It is drought-tolerant and thrives in high temperatures with little water. In Sydney's temperate climate, it is recommended to sow sesame seeds in late spring/early summer. Here are some detailed steps to follow for successful germination and growth:
Sowing and Germination:
- Choose a sunny spot in your garden with well-drained soil. Sesame plants require full sun and moist but not waterlogged soil.
- Sow the seeds at a depth of about twice the size of the seed.
- Lightly cover the seeds with a sterilized, soil-less starter mix.
- Keep the seeds moist until germination, which typically occurs within 10-14 days. Avoid over-watering, as sesame seeds prefer dry conditions.
- The optimal soil temperature for germination is 21°C (70°F).
Transplanting:
- Once the first true leaves form, you can transplant the seedlings into the ground or larger containers.
- If planting in the ground, space the plants about 60 cm apart in rows.
- To promote warmth and reduce water loss, consider transplanting into a raised bed or using black plastic mulch over the soil.
Sesame plants require little care once established and will continue to bloom and set seed capsules until the end of summer. With the right conditions and care, you can successfully grow sesame plants from seeds sown in late spring/early summer.

Germination takes 10-14 days
Sesame seeds are slow-growing and can take 90 to 150 days to harvest after planting. However, germination, which is the process of a plant sprouting from a seed, only takes 10 to 14 days. Sesame seeds should be planted in late spring or early summer, ensuring the soil temperature is at least 21°C (70°F) for optimal germination. The seeds should be covered lightly with a sterilized, soil-less starter mix and kept moist but not overly wet. Sesame plants thrive in full sun, so choose a sunny spot in your garden or place the seeds on a sunny windowsill.
Once the seeds have germinated and the first true leaves appear, you can transplant them into the ground or a larger container. Space the plants 60 cm apart if growing multiple sesame plants in the ground or a raised bed. Sesame plants can grow up to 1.5 meters tall, but they can also be grown successfully in smaller pots or containers.
It is important not to overwater sesame plants, as they are drought-tolerant and prefer dry conditions. Once the seedlings have sprouted, reduce watering to once a week until it is time to transplant them. Sesame plants do not require fertiliser and should be planted densely, about 15 cm apart in rows.

Sesame plants are drought-tolerant
Sesame plants require very hot, dry conditions with full sun and well-drained soil with a neutral pH. They favour moist and well-draining soil, but once established, they can tolerate drought and thrive in high temperatures with little water. It is important to note that sesame plants require adequate moisture for germination and early growth. While the crop can survive drought conditions, yields are significantly lower. Therefore, moisture levels before planting and flowering greatly impact yield.
To grow sesame plants, it is recommended to sow seeds indoors 4-6 weeks before the last average frost date. Keep the seeds moist until germination, but avoid a highly damp environment and do not over-water the seedlings. Sesame seeds should not be directly sown outdoors. Once germinated, the seedlings can be transplanted into the ground or a larger container. Sesame plants should be planted in a well-drained soil of medium texture and placed in full sun for optimal growth.
Sesame plants are relatively low-maintenance and can be a rewarding crop to grow in suitable environments. With their drought tolerance, sesame plants can thrive where other crops may struggle, making them a valuable crop for diverse agricultural regions.

Harvesting involves threshing and cleaning
Threshing and cleaning are vital processes in harvesting sesame seeds. Threshing separates the seeds from the chaff and debris, while cleaning removes any remaining impurities to ensure optimal seed quality.
Traditionally, threshing is done by beating the plants with sticks or shaking them to release the seeds from the pods. This can be done on a tarpaulin or a clean, hard surface to collect the seeds. In modern settings, portable, hand-held threshers or small machines are used to increase efficiency and reduce labour. Specialized combine harvesters designed for sesame crops can also perform threshing and cleaning in one pass, cutting down the time and labour required for harvesting.
After threshing, winnowing separates the seeds from the chaff and debris. This can be done by tossing the mixture in the air and letting the wind carry away the lighter chaff while the heavier seeds fall down. Specialized machines in modern settings perform this task with greater precision and speed.
The harvested seeds then undergo cleaning and drying to remove any remaining impurities and excess moisture before packaging and shipping. This process involves removing debris such as dirt, rocks, and plant material. Sieves, air blowers, and magnets are used to clean the seeds thoroughly. Finally, the seeds may be hulled to remove the outer bran layer, resulting in the familiar white sesame seeds.

Frequently asked questions
In Sydney, sesame seeds should be sown in late spring/early summer. It is important to wait until nighttime temperatures are above 15°C and the soil is at least 21°C.
Sesame seeds should be planted in rows in the ground, in weed-free beds. The seeds should be planted at a depth about twice the size of the seed. Sesame plants need full sun, moist and well-drained soil, and space to grow—space them 60cm apart if growing multiple plants.
Sesame seeds take 10-14 days to germinate. The plants will flower about 6 weeks later, and the entire growth cycle from planting to harvest is around 90-150 days.
