One of our three core roots is that we are Environmentally Conscious and for the past 30 years all the herbs grown at Jekka’s have been raised following sustainable, environmentally friendly and organic approaches resulting in a remarkable biodiversity at the herb farm.
Our herb seeds are also untreated and can be used to grow organic herb plants. Our seeds are hand packed into gassine bags, which are fully recyclable, compostable and biodegradable. These bags are then put into beautifully illustrated paper seed packets. Therefore, our environmental footprint is small.
