Aside from terrific results on tomatoes, chillies and potatoes, Shropshire Seaweed will enhance pretty much any vegetable you could care to mention: courgettes, cucumbers, radishes, carrots - the list goes on. You'll be amazed by the versatility of the feed and the range of veggies that it will improve. There really is only one rule when it comes to treating your produce - little and often. Mix 10ml of Shropshire Seaweed in 5l of water to create the perfect feed. It might not sound like a strong mixture, but seaweed extract is effective at very low levels. Then apply this solution as a spray directly to the foliage of your vegetables. Repeat every 10 to 14 days during summer - and combine with with a monthly root drench of the same concentration.
"I have been using this product for around 3 months now and have noticed a significant difference in the growth rate and health of the veggies I am using it for. I am using it on potatoes, parsnips, garlic, peppers, tomatoes, beetroot, broad, French & Italian bean varieties, onions, carrots and leeks. This summer in Scotland has been poor with a lot of rain and cloud however, if I measure my crops against my neighbours at the allotment, mine are some distance ahead in growth and health." - bogfairy
"Very good fertilizer. I use a capful in 5 litres of water, once every fortnight. Happy plants and loads of veggies!" - Sid
"I bought this at the start of the season as a few of my plants looked like they needed a boost. The results were quick and noticeable. My french beans went from looking yellow and weak to strong and green in less than 10 days." - Adam F
"I try to be organic in my garden and on the allotment and this product fits in well. It certainly seems to have worked on my veg this year. I have used it on my courgettes and whilst all the plots around me are struggling to get their plants going, I have a glut! I will definitely be purchasing this product again." - sarah
Seaweed's unique biology nourishes and stimulates plants in a host of ways. Taken together the effect is a powerful organic feed that promotes strong growth and healthy, resilient crops.
Special growth hormones called cytokinins and auxins act like 'plant steroids.' They're absorbed directly through the foliage and result in larger vegetables; juicier fruits with longer shelf-lives; and fuller crops across the board.
Seaweed's plant hormones also work below the surface, stimulating the development of more extensive root systems. This helps to increase water access, resistance to root diseases, and offers protection against wind damage.
Alginates are a well-known 'clay improver' and also help to hold water in the topsoil. Meanwhile, seaweed encourages microbes within the soil to convert unavailable nutrients into a form that plants can actually use.
Seaweed contains many vital micronutrients that help protect against stress and disease. Alginic acid and mannitol, also present in seaweed, are superb carriers of these elements, taking them straight to where they're needed.
Seaweed increases the amount of chlorophyll in leaves, allowing plants to better harness energy from the sun. With more energy plants enjoy stronger growth and appear greener, healthier and more vibrant.
Shropshire Seaweed's unique mix of growth hormones and nutrients offers an immediate pick-me-up to plants of all shapes and sizes. Over the medium-to-long-term, they'll also enjoy signifcant improvements in terms of soil quality, root structure and energy capture. Seaweed creates a complimentary environment for healthier plants and stronger growth. And best of all: it's totally organic.

Shropshire Seaweed's success is down to the word of mouth endorsements by customers who have tried it and seen the results for themselves.
Since being launched in 2011, Shropshire Seaweed has risen to become the best-selling organic feed on Amazon.co.uk thanks to the massive volume of customer reviews and endorsements. Check out what our customers have been saying by following this link.
Below is a collection of images sent to us by our loyal customers.
So, how did a landlocked county produce a seaweed company?
Over 100 miles from the nearest coastline, Shropshire is the last place you'd expect to find a seaweed company. When we tell local people what we do, they often look at us like we're completely mad! However, here in the heart of rural England, we do think we know a thing or two about organic living and 'the good life,' which is what drove us to develop Shropshire Seaweed.
Of course, there's no seaweed to be found growing around these parts. We have to go to Ireland for that. The waters there are some of the cleanest in the North Atlantic, which helps to produce the healthiest and best Ascophyllum nodosum around. All the seaweed we use is grown and harvested on a sustainable scale, then it's dried and brought by sea for processing.
Shropshire Seaweed is a highly versatile plant feed. Select your application from the grid below to find out how to get the best out of it. You can also read about some of our growers' experiences.
Tomatoes are a staple of many a British garden and allotment. They also benefit greatly from a regular hit of Shropshire Seaweed. During the growing season, we recommend foliar spraying the leaves of your tomato plants every 10 days with a solution that is one part seaweed and 500 parts water. This should help improve the overall health of the plant and the size and shelf life of your juicy tommies. For better results, combine the regular foliar feeding with a monthly root drench at around double the concentration. Shropshire Seaweed is recommended for use on tomatoes by TomatoGrowingExpert.com and GiantVeg.co.uk. Ian Neale of GiantVeg.co.uk used Shropshire Seaweed to help help grow the UK's largest ever tomoato - a 2.6 kg effort (below) in 2013. What Our Growers Say "Used this last season on tomatoes. Had a great crop and stayed blight free. Will get some more next season." - Little Jim
Shropshire Seaweed has really made a name for itself amongst chilli growers in the UK and beyond. In 2014, one of our customers grew a prize-winning Dorset Naga plant which sprouted an incredible 2,256 chillies in a single year (read how he did it, here). If you want to try to outdo that, the best approach to feeding is little and often. Mixing 10ml of Shropshire Seaweed in 5l of water will provide a fanatastic fertilizer to use as a foliar spray. Apply liberally every 7 to 10 days during the growing period for a bumper crop of spicy chillies. Shropshire Seaweed is recommended for use on chillies by Dartmoor Chilli Farm, jalapeno.nu and Bountiful Seeds.
Enjoy juicier apples and pears by treating them throughout the summer with a weekly spray of liquid fertilizer. These fruits typically require a stronger concentration of Shropshire Seaweed than that used in other applications - around 50ml in 10l of water - but the investment is worth it. Mix and spray directly onto the leaves of the tree from April to September. What Our Growers Say "Great stuff. I use this once a week (two cap fulls in a large watering can) on my fruit trees - pear, apple and plum. The pear tree got rust really badly and I picked off virtually all the leaves. I then treated it with this and nearly straight away new shoots came and these grew on to be really healthy." - DR
Did you know you can use Shropshire Seaweed to make your lawn the envy of the street? Regular feeding throughout the growing season (late March to October) will leave your grass looking thick, healthy and green. It is also an effective treatment for the recovery of tired or damaged lawns or for boosting newly-laid turf. That's why liquid seaweed is the feed of choice on golf courses and prestige lawns the world over. Use the table below to work out your requirements and try to ensure an even spread across the whole area. If you are treating a large surface, we would recommend a backpack sprayer system. Otherwise a watering can does the job just as well. Application Mix stated amount with cold water at a ratio of 1:50 Typical Lawn (10m x 10m) Acre (4,000m2) Hectare (10,000m2) Recovery or Relaying Dosage per fortnight; Repeat four times 200ml 8l 20l General Maintenance Dosage recommended for every four weeks 100ml to 200ml 2l 5l What Our Growers Say "I gave it a go on our lawn with excellent results. Grass is thicker and greener: it was just a mass of yellow and sickly looking grass in the spring. With a bit of Verdone weed killer applied and a couple of sprays with the seaweed, it's starting to look a lot better. Picture below" - GSARider
Organic liquid seaweed fertilizer is renowned for its ability to rejuvenate box hedges and shrubs following winter weather. Mix approximately 15ml of Shropshire Seaweed with 5 litres of water and spray the solution directly onto the plant's leaves as a foliar feed, taking care to apply it as evenly as possible. Keep up this level of treatment once a week throughout the summer months. What Our Growers Say "I have used it once a week for the last few weeks on a beech hedge which was planted a few years ago and I think that at last it has decided to grow." - D. Onions "The pyracantha hedge is growing properly for the first time in years." - Amazon Customer "I have a young box hedge (buxus sempervirens) that was planted in last year, and despite being well cared for, was showing signs of struggling. It's now had two feeds with this fertiliser during April and has quite dramatically started to flourish with quite vigorous new growth." - Small Scale
Hanging baskets are many gardeners' pride and joy, so to keep them looking in tip-top condition, we recommend a higher concentration of Shropshire Seaweed. Around 15ml of seaweed extract, diluted in 5l of water, should be used and this should be sprayed evenly across the baskets at every watering throughout the summer months. What Our Growers Say "Best fertiliser I have ever used. Has done wonders for my garden. Have just bought my third bottle. Last year my baskets and containers were the best ever." - Cas Evans
Strawberries, raspberries and cherries really enjoy the good pick me up that seaweed offers. You'll want to mix around 50ml of the extract in 10l of water and spray directly to the foliage of these plants every 7 days throughout the growing season. For best results, combine the foliar feeding with a monthly root drench - use the same concentration of product for this as well. Soft fruits treated in this way should be larger in form, juicier and last longer once picked. What Our Growers Say "Started feeding my strawberries from the day I put them back in the greenhouse, beginning of March. They are huge and very sweet. The first one was ready May 18th in a non-heated house." - Bob Warwick
Shropshire Seaweed is a good way to lift a tired-looking flower bed. It's a great all-round, versatile feed and gets fantastic results on annuals, biennials and perennials. Mix 10ml of the seaweed extract in a full 5l watering can and feed your beds on a weekly basis, taking care to apply the solution to the heads, leaves and branches of the flowers as well as the soil below. What Our Growers Say "Wow! Put some on the ailing sweetpeas and they have turned into triffids!!. Wish I had found it earlier!" - Jane Boss "Bought the product primarily for my lawn, but have used it in beds, borders and containers and within a couple of days it looked like the gardening fairy had visited!" - Susan Gray "Good for roses. An instant feed that keeps leaves healthy. Do it regularly and you will notice the difference. Excellent." - Catherine Andrewartha

Groundsmen the world over use seaweed on sporting and prestige lawns because of the regular, strong growth it promotes, and for how green the grass starts to look after just a couple of applications. Depending upon the desired results, we recommend a Shropshire Seaweed dosage of between 4 and 8 litres per acre every 4 weeks during the growing season. Of course, this amount should be diluted at around 1:50 with water and spread evenly. Shropshire Seaweed is perfectly compatible with other targeted supplements and pesticides.
Hydroponics is a rapidly expanding sector on the British growing landscape - and here too seaweed extract is a very beneficial supplement. Shropshire Seaweed should be dilluted at a rate of no more than 1:2000 in the system reservoir and can be combined with a two-weekly foliar spray of the crops themselves.
Did you know that the Jersey Royal potato is traditionally grown under layers of seaweed? It's how it gets its unique, delicious taste. Your own spuds can benefit from the same treatment if you employ a liquid seaweed feed. Mix 10ml of Shropshire Seaweed with 5l of water and spray this mixture directly onto the leaves of the crop every 7 days throughout the growing season. When you dig them up you should find the potatos are larger and tastier - and they should last longer in the pantry as well.
Seaweed can be used to boost herbs and salad crops, helping grow-your-own homes to enjoy larger and tastier yields. Every 10 days, administer a foliar spray of diluted seaweed evenly across the plants. You should mix the product at a rate of 1:500 with cold water. You may find a trigger spray bottle the best and most accurate way of treating these delicate plants.
Shropshire Seaweed helps to encourage the germination and propagation of seeds and seedlings when applied prior to planting or whilst transplanting. Seeds are best served by soaking them for 12 hours in a weak solution - 5ml of Shropshire Seaweed in 5l of water. When you take them out of the solution, plant them immediately. Double the concentration to 10ml of Shropshire Seaweed (again in 5l of water) for seedlings and dip roots in the solution prior to planting out. What Our Growers Say "Soaked seeds for 12 hours before sowing. Had 95% germination. A must for all gardeners." - W. Baker "The results are outstanding for use on seedlings and established plants, using it to root feed and foliage feed. In a word: brill!" - donwilky
If you own paddocks or grazing land, seaweed extract is a low-cost way of keeping the grass in good condition for your animals. It's also totally organic and offers no threat to the health of horses, cows or sheep. You don't even need to clear them out of the field to apply it. Mix 2l of Shropshire Seaweed per acre (or 5l per hectare) and mix out at a rate of 1:50 with water. Apply evenly across the area every four weeks from spring to autumn.
Aside from terrific results on tomatoes, chillies and potatoes, Shropshire Seaweed will enhance pretty much any vegetable you could care to mention: courgettes, cucumbers, radishes, carrots - the list goes on. You'll be amazed by the versatility of the feed and the range of veggies that it will improve. There really is only one rule when it comes to treating your produce - little and often.

One of the most common questions we get asked by growers is whether Shropshire Seaweed is suitable for use on erciaceous or acid-loving plants, such as rhododendrons, azaleas and camellias. Well, we're happy to say that, yes, the product is perfectly compatible. Seaweed has a pH of approximately 6.0, so it will not cause any detrimental change to the growing environment. On top of that, the product's growth hormones and nutrients are effective right across the plant spectrum. Individual species may also require soil amendments or iron supplements depending upon the nature of your soil - if you're unsure, consult your local garden centre for advice.
Shropshire Seaweed contains no chemicals or supplements and is approved for use in organic systems by Organic Farmers and Growers. It therefore poses no health and safety risk to the user when handled in accordance with good practice. No gloves are required for handling and you are free to spray your plants in the company of pets and small children. It is also totally compatible with all other nutrients, supplements, fertilizers and pesticides, either organic or otherwise. We ask that all customers follow the instructions laid out on this website for the plant you wish to treat. If you have any questions, please contact us on 01952 677002. Shropshire Seaweed has a shelf-life of 24 months in its original container. It should be stored out of direct sunlight (it breaks up the carbohydrates in the solution) and protected from frost where necessary. Despite posing no threat to the environment, animals or humans, the product should still be disposed of in accordance with local regulations.
Seaweed extract is a useful solution for turning around sorry-looking trees. As it is applied as a foliar spray, it can be targeted at dry or diseased parts of the plants, such as leaves and branches. Again you only need a small amount of seaweed extract - around 20ml in 5l of water - but keep up a feed frequency of every 7 to 10 days. Of course, a regular foliar spray of seaweed will also help seemingly healthy trees, often encouraging them to produce more and bigger fruits. What Our Growers Say "I have a very large olive tree that just grows and grows and never produces olives. I researched and the advice I found said try this. I bought it and used it regularly. My olive tree has now flowered and appears to be starting to grow olives - very exciting!" - Amazon customer "I now have an olive on my little olive tree! Will definitely be ordering more!" - Susan Gray "I bought this product to save my peach tree. It does the job brilliantly. Also it works perfectly on other flowers and plants. If you want a beautiful garden, start using this organic fertilizer. I will keep buying it." - Liming Sun
Shropshire Seaweed builds upon a long-history of using kelp in British agriculture
Historians have discovered that seaweed has been harvested for use as a plant supplement since Roman times, with the earliest evidence of its use being in the Scottish islands. The practice appears to have caught on and by the nineteenth-century many British coastal locations boasted their own seaweed gathering operations.
Until relatively recently seaweed cultivation stayed limited to coastal regions due to the difficulty in transporting the heavy kelp cross-country. However, advances in drying and processing techniques have now made seaweed a convenient liquid feed and it's used the world over.
Modern gardeners who use liquid kelp extract, such as Shropshire Seaweed, continue a British growing tradition stretching back over 1,500 years.
