A method for growing herbs comprising planting (201) a herb and allowing the herb to germinate (202), becoming a herb seedling (2) and either transplanting to or maintaining (203) the herb seedling in a restrictive container (3), where the herb seedling is held for a predetermined period of time before transplanting (204) the herb seedling to a second stage, where the seedling is held in order to grow and develop a larger root system. Maintaining the herb seedling in a restrictive container has the effect that the herb's root system will be prevented from growing, in comparison to a herb planted in a nursery. The herb will essentially stop growing while the root system is restricted. Meanwhile the herb will continue maturing, developing oils which are more elastic. Herbs with more elastic oils will be significantly more resistant to cold temperatures at a harvesting size, compared to herbs that have not been transplanted to restrictive containers.
