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.
