Review: Great fertiliser for the lawn, plant pots, flowers, veg beds, the whole garden! - At first when this arrived, the bottle was bulging a little, as though it wanted to explode. Slightly alarming, but at least it was full to the brim. The in-built spout is handy, and you can measure it out with minimal mess. As you'd expect, it's a deep green liquid, so be careful! Now I've used some, the bottle stands up properly and doesn't look like it's ready to blow! I used some in a sprayer, and added some iron sulphate (as suggested by some online professionals). It mixed easily with water, and sprayed without clogging. Just be careful not to get it onto clothes or paths, as they'll be stained green. After a week or so, the grass is noticeably a deeper green. A visitor even commented on how lush it looks (I hope my wife hadn't prompted them to say this!). On my fairly modest lawns, the bottle should last a year or maybe two, so it's really decent value.
Review: Kelp plant fertiliser. - I bought this seaweed fertiliser to feed my house plant and cacti. Kelp is known to have a lot of potassium which is beneficial for flowering cacti. The bottle arrived safely with no leakages. The liquid inside has dark brown colour. Doesn't smell much of anything. I diluted it as per instructions. The plants seem to like it but it's hard to tell as they can't speak human language. No side effects observed which is good. I also used diluted fertiliser to soak seeds before sowing and I can tell it was beneficial. Good for soaking seeds and watering seedlings. It's very economical so will last me for ages. I like it's natural and organic with no nasty chemicals in it. Can highly recommend for plants which need potassium. Hope it helps.

### ⭐⭐⭐⭐⭐ Great fertiliser for the lawn, plant pots, flowers, veg beds, the whole garden!
*by F***N on 30 December 2025*

At first when this arrived, the bottle was bulging a little, as though it wanted to explode. Slightly alarming, but at least it was full to the brim.

### ⭐⭐⭐⭐ Excellent plant food
*by P***N on 6 June 2022*

Used this across all of my vegetables and soft fruit plants and within a month they had increased in around 20% more growth than expected / normal. Will buy again and so far pleased with the results. Organic as well which is a must have. Be nice to your plants and go get some of this - they will thank you for it. Only down side it that weeds also like it to make sure you keep you garden weed free.
