Shropshire Seaweed is a highly effective feed for tomatoes, helping to produce large juicy fruits and plants which are more resistant to blight. The most effective method by far for tomoatoes is to apply the feed as a foliar spray directly to the leaves every 14 days throughout the growing season. This should be done at a dilution rate of 2ml per litre of water.
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 fantastic 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.
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.

Organic liquid seaweed fertilizer is renowned for its ability to rejuvenate box hedges and shrubs following winter weather.

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.

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.

When you dig them up you should find the potatos are larger and tastier - and they should last longer in the pantry as well.

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.

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 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.
