Months of wild harvest wrack production
We have developed a detailed knowledge of harvest seasons. Specifically, it may be possible to pick small quantities of a variety early in a season, but we delay first harvest until the rates reach commercial scale. Indicative seasons for our key species are given below. Please contact us if you would like to learn more about production months.
