Excellent plant food.
I bought this as the 1 litre bottle is almost empty. The price per litre is much cheaper and will last nearly a year. This plant food has given my container plants a real boost.I've used it for 2 months,and despite the frequent heatwaves my plants are in full bloom,healthy foliage.I'm very pleased.

Good product, don’t use too much
Good product helps the grass to grow. All I would say it don’t use too much as it can cause ph imbalance in your soil, leading your lawn to go yellow

Love it.
This is the best purchase I’ve ever made. The quality of the feed is very good, and you only need a small amount for the five litre can. My flowers are looking happier and stronger now. It’s a great value for money, and I’ve been using it for a month now, and there’s still plenty left. The smell is fine, but that’s not the most important thing to me. I love the size and design of the bottle, and how they made it is incredible.

Easy to mix and use, good value lawn and vegetable plant treatment
We’ve been using it for some weeks now to feed our lawn and vegetables and have really noticed the difference. Previously our lawn was patchy but with this treatment the grass seems thicker and stronger and green. It’s easy to use, measurements are given just follow the instructions.

Good product, flawed bottle design?
Product seems good, plants respond well when watered with a liquid seaweed solution. However I find the integral measuring reservoir difficult to I use and therefore won't be buying again.
