Quality at reasonable price.
The best plant fertiliser I’ve ever had. Difference to outdoor potted plants noticeable in 24 hours. Can be heavily diluted with water but still shows results. Good container which when squeezed measures out required amount in a built-in cup at the top. Price very reasonable and will purchase again.

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.

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.

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.

It’s plant food. It works.
It’s plant food. It works. It’s not a scam product like so many things that are popping up on Amazon these days.
