Seaweed organic bio-stimulant

Awsome. Used to use a seaweed fertiliser from a previous supplier but that was only in there summer fertiliser!
This is great as can use this all year round! Meaning I can have my 'summer' lawn all year round!
Lawn has improved loads.

Uses it on my plants aswell recently and plants looking a healthier colour even if there isn't much growth! 😀

Wait till I use it in the summer and get it's full potential out of it!

Much better then a miracle grow fertiliser I been using which didn't seem to do much at all.
