For herb plants, please see our Looking Good List for availability. You can organise a Farm Collection, collect at one of our Open Days or during a Herb Experience. Please use our online webform or email your list directly to us (firstname.lastname@example.org). We no longer offer a general mail order service for our herb plants but we do offer a limited selection of Jekka's Culinary Herb Boxes.
At Jekka’s we sell herbs in 1 Ltr and 2 Ltr pots. These are established and hardy herb plants that are grown following organic principals and to survive the UK climate. Please read Jekka's blog that contains her top steps to growing on your herbs.
There is also ‘Jekka’s Seasonal Tips’ series that covers growing and maintaining herbs in early spring, late spring, summer and autumn & winter. Together they form Jekka’s guide on how to grow herbs. For a hands-on herb experience, where you will learn how to grow herbs, check out our Master Classes.
Our herbs are designed to be grown in containers or planted in the garden. Although some herbs will be quite happy indoors, most prefer being outside. Please see our indoor growing blog for more information.
If you think your herbs need a little more attention we always recommend an environmentally friendly solution, and these are Jekka's top three:
- Maxicrop liquid seaweed: 'Feed on Fridays' as Jekka always says for all round good plant health.
- SB Invigorator: a safe and effective insecticide and fungicide to help control a wide range of pest species
- Epsom salts: the horticultural equivalent of what you put in your bath that will top up the plant's magnesium and stop orange leaves.
Please note, the compost in Jekka's Kits will have enough natural food for approximately 6 weeks.
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.
