– SeaFeed Xtra – Organic Seaweed Fertiliser, Liquid Outdoor Plant Food Ideal for all Plants, Lawns, Gardens and House Plants, Rich in Additional Nutrients - 1 Litre Makes up to 500L

Promotes healthy growth: Many users report greener foliage, stronger root development, and improved flowering after regular use. * Suitable for most plants: It can be used on vegetables, flowers, lawns, shrubs, fruit, and houseplants. * Organic biostimulant: Made from seaweed (Ascophyllum nodosum) with added vinasse, which provides potassium. Seaweed extracts are valued more for stimulating plant health and stress tolerance than for supplying large amounts of nutrients. * Good customer satisfaction: The manufacturer reports an average rating of around 4.8/5 from over 280 reviews, with users praising plant health and value for money. Cons * Not a complete fertiliser: Liquid seaweed is relatively low in nitrogen, phosphorus, and potassium. Heavy-feeding plants like tomatoes, cucumbers, and peppers will still need a balanced fertiliser alongside it. * Bottle design: A recurring criticism is that the built-in measuring chamber can be awkward to use. * Results are gradual: Seaweed products work best as a regular supplement rather than a quick fix. Overall Rating: 4.5–5/5 It’s a good choice if you want an organic supplement to improve overall plant health, root growth, and resilience. For maximum performance, especially with fruiting crops, pair it with a balanced tomato or vegetable feed rather than relying on the seaweed alone.

Purchased the 1L version and WOW... Its brought my neighbour's plants back to life after being neglected in their absence. They were dead, dying, brown, wilting - the lot. Plain water helped perk them up a bit, but I felt there must be more to truly bring them back from the dead... and then I came across Liquid Seaweed (and the thousands of positive reviews). Now I can see why! I now have another problem I didn't anticipate...I was only trying to keep them alive. Instead I've inadvertently created a Jack-and-the-Beanstalk situation for a few of them. Vertically challenged doesn't begin to cover it - a ladder simply will not suffice. I'm going to need a cherry picker to hoist me up there. The odour is neither pleasant nor offensive - just very mild and perfectly tolerable. Instructions are clear and it’s brilliantly versatile: I’ve used it successfully on everything from potted plants to bedded shrubs. Excellent value for money, though the quantity goes fairly quickly with the amount of water I use (about 5 L of this every two months). So if you want not only revived plants but thick, tree-trunk-like branches and several feet of rampant growth... don't wait. Purchase now!

Bought this a few times now. Really like this product. Easy to measure out how much you need with the measuring chamber at the top. Whenever I use it I can notice an improvement in my plants health and growth. Lasts a long time, great value for money. Normally lasts a few months and I have a lot of house plants.

I'm not sure (yet) how effective this stuff is or will be as it is early days. It mixes well in my watering can, and there is a very helpful squeeze thing at the top which allows you to measure exactly how much you need just by squeezing the bottle, causing the fertiliser to travel up a thin straw like spout into the measuring chamber. Then when you tip the bottle to pour it out, only the fertiliser you squeezed into the measuring chamber comes out. Genius. I used this on a newly overseeded lawn, so hopefully it will encourage the grass root development, giving me a lush, green, thick lawn. Based on the amount of concentrate I used for my lawn, it should last me quite some time.

The first application did an excellent job of greening up the lawn

Was told about this by my son.It has fed the plants and grass very good product

The product is excellent and has had noticeable results on my large potted bay & palm trees. 5 out 5 stars for quality of product. However the bottle design is terrible 0 out of 5 stars. They’ve tried to be clever by building in the measuring cup into the top of the bottle and then having a side tube you squeeze to fill the measuring cup. It doesn’t work and is a pointless over engineered design. Apparently they must think that filling a separate measuring cup from a bottle is problematic for most people. I had to saw off top with my jig saw and put into another bottle. Won’t buy again for this reason.

Plants love this product , used this product on my garden plants , very versatile, All looking healthy and thriving well. Odorless , money well spent.

Fungerar bra!

livraison très rapide, dans un carton, gros bidon à bonne odeur maritime et j'espère que ça va fonctionner après les autres (sucre de canne et guano^^) pour mes plantes d'intérieur peu résistantes pour l'été, et pour leurs feuilles bien trop petites. En tant que bretonne, j'ai confiance dans les qualités des algues, que je vais mixer en brumisant fish-mix de biobizz, un essai écolo à voir...Essai qui fonctionne parfaitement, que je fais tous les samedis : les plantes adorent, droites et bien vertes, avec bourgeons sans arrêt, je recommande cet engrais que je reprendrai dès que vide!

è dotato di un dosatore sul tappo che garantisce l'esatta misura d'uso nel miscelarlo in acqua. L'etichetta dà le corrette indicazioni. inoltre evita sprechi, anche se occorre porre attenzione durante il versamento perché la bocca del contenitore non ha una guida di fuoriuscita. Nei vasi di fiori o piante ornamentali è eccezionale. nel mio caso i risultati sono visibili già dalla prima settimana. Un po' meno per le piante dirette nel terreno per le quali forse ci vorrebbe un'innaffiatura molto copiosa usando questo fertilizzante che lo rende poco conveniente. Però dove l'ho usato, alberello di limone in aiuola o pianta di rosmarino direttamente a terra etc. ho rilevato che in maniera parziale, c'è stato un buon rinvigorimento. Non sono un esperto per cui lascio ad altri i confronti con altri prodotti.

Product was promptly delivered, well sealed. Product works miracles, thanks.

Buen producto
