envii Seafeed Xtra - Organic Liquid Seaweed Fertiliser - 10 Litre

I have been growing vegetables for many years. But this year I have been spraying all the leaves with this seaweed once a week. The vegetables are massive. Everything is growing quickly. Much quicker than previous years and all my neighbours. I started eating the cucumbers and tomatoes at the beginning of June. Considering Beast from the East weather storm hit the UK to delay the 2018 growing season. This stuff has made my plants grow really quick. My sprout leaves are 3 ft long!! Everything is growing so well. Will never be without this stuff. One bottle will last ages as you only use 10 ml per 5 lire of water in a pressure sprayer. I spray the leaves top and underneath. I don't think the slugs like this stuff because I have very little slug damage, considering my vegetable patch is next to a 120 year old stone wall which is a snail hotel. Normally the snails are a huge problem. But not this year

I am not sure how much seaweed actually does for plants, but compared to other seaweed products, this seems quite good and works out cheaper per litre diluted than many others. The dilution rates vary for this, depending on plant type and application. Lowest dilution starts at 2 ml per litre and it goes up to 5 ml per litre. At 3 ml per litre, I worked out that this comes to just under 3 p per litre of diluted solution. Most other seaweed products I looked at were at least 5 p per litre, especially if produced through cold pressing, like this one, which preserves more beneficial ingredients. Seaweed is not a fertiliser as such, although this has added Urea, iron and amino acids. The addition of urea is the only thing about this product I'm not sure about, although I like the added amino acids. While adding an N source can be beneficial, if you're using this with other fertilisers, you might end up with too much N. Also, fertilisers containing urea should only be used when soil is above a certain temperature, think it's 10 C. I see they've now added info on NPK values, which is good. At medium dilution rate, it added 0.4 mS to EC when I tested, so adds quite a bit of dissolved salts. As well as watering in and foliar feeding, I use seaweed products to soak seeds before sowing. Having now seen the N content, I doubt this is suitable for soaking seeds, and have purchased a different product for that purpose. I wonder if the N source/urea is also organic, or just the seaweed itself? I use mineral fertilisers myself, so am not bothered, but if you only use organic products, you might want to enquire. Find it annoying that this company routinely omits ingredient transparency, and do not understand why. It's not necessary to give away any trade secrets.. I've marked other products down to 4 stars because of this, but because this gives quite a bit of other info, like seaweed solid content and manufacturing processes, and now NPK values, have given this one 5 stars, also because of good price.

I plant trees on behalf of the Woodland Trust and some of those recently planted were showing signsof distress due to the continuing lack of rainfall and very hot conditions. After readingreviews for this product I have begun using it whilst watering the trees. The resultsare quite amazing. Over the course of ten days new leaf buds are appearing from areaswhich previously looked dead. Cannot recommend this product strongly enough.

I had heard about seawewd for vegetables whilst in Cornwall. I did some research so bought this after seeing good comments. In 5.5 weeks my runner bean plants are fabulous, never have they looked as good as this! 5 stars 😊😊😊😊

Well I read the reviews and thought why not. I did read people were having trouble with dispensing the right amount of liquid and that it was making a lot of mess. Easy solution to that is remove the cap, hold the bottle upright and squeeze slowly. I've been using this product since early June and I have seen a big difference in the size of flowers and plants. I took some pictures before and after. The rate of growth has been amazing but try it for yourself. I would definitely order this again.

Yes. It’s good. The best thing is the built in measuring system. Can notice in a day or 2 plants look greener and grow rapidly, but all the brands I’ve tried do that. For me the measuring thing keeps me buying this and the solid plastic container. It also has no bits in it allowing me to use it in a sprayer, unlike some other brands

Have found this to be excellent, have not used it for too long, but certainly found it made my citrus flower there socks off which they have not done before. Only criticism is the container is difficult to use and could do with some measuring marks on the side so you do not use too much.

This is the second lot of seafeed xtra that i've bought. It's very easy to use with its special dispensing system - you squeeze the bottle and the extract rises into the non-return measure at the top and then all you have to do is add it to a watering can and top up with water.What i didn't realise, until too late, is that the extract stains clothing. My tomatoes looked in need of some perking up and I watered them with diluted Envii on a windy day. Some of the product splashed on my skirt and I can't remove the brown stains. I'll carry on using Envii, but I'll make sure I'm wearing my old gardening clothes when I do.
