Has my plants growing like weeds
I bought this along with a spray bottle to try both misting and watering my plants with it. If you don't like long reviews, I'll be straight up and say it works brilliantly well and my plant pot budget has gone up from all of these massive plants! Seaweed fertiliser seemed like a logical purpose to me. I'm a big fan of both organic and sustainable gardening. It makes sense to cut out the supermarket middleman and grow your own organic produce for a fraction of a fraction of the price. It grows naturally across the world and, unlike peat moss, is harvested in a way that has no negative effects on marine ecosystems. That really appealed to me as I would feel guilty if I was contributing to the destruction of our planet with my vanity project. On to the effects: seaweed fertiliser increases pest/disease resistance, works as a nitrogen fixer (more on that later), increases fruit production, provides better foliage, and is 100% natural. As a nitrogen fixer, it doesn't include the nitrogen your plants need, but increases the amount of nitrogen in the soil by creating a better environment for the bacteria that produces it. That can sometimes be all you need to work on nitrogen deficiencies if they're not major. With all of its benefits, all you really have to do is pick a good brand and you're away. Vitax seemed trustworthy to me, and they have a very good price for a litre of concentrate. A capful is good for 8 litres of water, so you will have to be gardening on an industrial scale to run out of this any time soon. Unfortunately I'm running out as my friends have been taking bits home after they've seen what it can do. Try it. It can't hurt to give it a go, and you will be very surprised to see what a month of seaweed can do for your plants.

Seaweed fertiliser
Initially I thought that this was an expensive way to purchase liquid fertilizer. However as the season draws to a close I find that I have only used 4/5 ths. of the first bottle. Naturally one has to apply selectively, my application was limited to : tomatoes and freshly planted rose bushes. A little does go a long way, and the tomatoes are better this year. Will use again next year.

Convenient to store and use; use was recommended
Vitax 1L Organic Liquid Seaweed is used as a plant fertiliser when suitably diluted. It can also be used to help remove and deter bugs from the leaves when used as a spray wash. Dilution rates are printed on the label but there is no obvious Use By date so it may be good for a couple of growing seasons or more. It has been suggested to use this as an alternative to fish, blood and bone or chicken pellets both of which are foul smelling and, when previously used by neighbours, attracted several complaints causing them to cease using the products. Seaweed extracts are known to be used as components of certain top-rated fertilisers but, as such products are sold in huge quantities unsuited to our small garden space, their purchase is not justified. A bottle of this size is more practical and convenient as a small amount is added to a quantity of water in a can. Storage is much simplified and not smelly.

Best plant food ever.
This is by far the best plant food I have ever used. I used it for the first time last year and saw a huge improvement in my plants tomatoes and my new plumb tree. I will use it on strawberrys and rasberrys this year.

Empecé a usarlo hace unos meses con mis orquídeas, en la proporción que indica el fabricante, y una vez a la semana. En cosa de un par de semanas ya se notaba cómo las plantas estaban sacando muchas más raíces, que estaban creciendo con más fuerza y con tallos y hojas más fuertes. También parece que sirve para reanimar plantas que están un poco pachuchas, y me ha ayudado con los típicos esquejes que no hay forma de enraizar (cosa que con hormonas enraizantes no me funcionaba). En definitiva, un muy buen producto para todas las plantas en general.
