Review: Good stuff, plants will thank you for it. - Good stuff. I find seaweed fertiliser provides an excellent supply of nutrients for vegetables on the allotment. It is a natural, safe feed and provides the plants with an extra top up when used alternatively in combination with a regular feed. The envii container is very good with no leakage and easy to use.
Review: A great addition, green lawn! - Amazing product, used with fertiliser and scarifying/aerating and the results in 22 days are better than i could have expected. Photos speak for themselves, taken 3 weeks apart believe it or not!
