envii SeaFeed Xtra – Organic Liquid Seaweed Fertiliser, Outdoor Plant Food Ideal for all Plants, Lawns, Gardens and House Plants, Rich in Additional Nutrients - 5 Litre

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.OverallRating: 4.5–5/5It’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.

Seemed to help my rhubarb and potted plants. I found it good.

Good stuff. I find seaweed fertiliser provides an excellent supply of nutrients for vegetables on the allotment. It is a natural, safe feed and provides the plants with an extra top up when used alternatively in combination with a regular feed. The envii container is very good with no leakage and easy to use.

Super easy measure so no overdoses or spills. Plants doing really well on it especially dahlias

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.

I've been using this fertiliser for just over a month now and I have to say my plants have been absolutely flourishing since I used the first application. I could not recommend this product more; it has become an essential part of growing my plants over the summer.

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.

He comprado ya una 20 garrafas de 5 litros de este producto (el paack de cuatro sale a mitad de precio) y la verdad es que aunque a priori es caro, vale muchísimo la pena. Me explico. Yo lo uso de dos maneras, la primera para revitalizar plantas que están un poco pachuchas y la segunda, para acelerar radicalmente el crecimiento de las plantas, sobre todo el primer año. Este producto consigue que cualquier planta mustia, con pinta de morirse o de esas que no van "ni p'alante ni p'atras" vuelva a la vida, literalmente resucite. Incluso ha revitalizado una palmera de 7 metros que sufrió mucho en el trasplante, estuvo un año agonizante, todo el mundo que pasaba la sentenciaba y a partir de echarle este producto revitalizó. El ahorro es muy grande, porque las plantas son muy caras y con un par de chorritos del producto en el agua de riego las salvas. Respecto a acelerar el crecimiento, tendríais que ver mis geranios, con apenas un chorrito en el agua de riego al mes y a pesar de estar en una maceta más bien pequeña son tan frondosos y altos que hasta un pájaro ha hecho un nido dentro. Por cierto, la hiedra que estaba en la base de la palmera y recibió muchísimo producto, se ha hecho inmensa. Este es otro ahorro porque con este producto puedes comprar en el vivero plantas más pequeñas, que de hecho se adaptan mejor y que son más baratas, sabiendo que con este producto en la mitad de tiempo se hacen el doble de grandes. Lo he regalado a amigos y todos alucinan.
