Growing Roselle

Indoor Sowing: Late Winter and Early Spring.

Direct Sowing: Spring and Summer.

• To grow hibiscus from seed you must first scarify the seed by nicking or sanding the seeds. This helps to get moisture into the seeds to improve the germination rate.
• Plant the seeds in the growing medium and keep the soil moist until germination.
• In temperate zones, start hibiscus in pots at the same time as you would tomatoes.
• When seedlings are about 11cm, transplant them to a sunny spot in the garden.
• Hibiscus grows well in soil with a high level of organic matter, but too much nitrogen will delay flowering.
• Keep plants evenly moist & well-weeded until they are about 60cm high.
• Once this height is reached, mulch the plants to retain moisture and keep weeds at bay.
• Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil.
• Suitable pH: acid, neutral and basic (alkaline) soils.

Pick young calyxes by hand when still tender or use garden clippers once stems have gotten tough. Pick approx. 10 days after flowers open at the beginning or the end of the day. Harvesting the calyxes early promotes greater yields. Around 6 weeks, the young edible leaves & shoots can be picked.

Fresh calyxes are typically dried or dehydrated prior to storage. You can keep them fresh in the ‘fridge for 4 – 7 days. Leaves & stem tips can be stored in the refrigerator for about a week.
