Have purchased before and happy with the quality of this and most importantly, so are my plants.
Have been using this for years - keeps my houseplants super happy!
I ordered a 2.5L bag and have loads left
So nice and fine. I add to the top of my favourite plants in pots
Excellent product. I have just started using it on my plants this spring and hoping they will bloom through summer and beyond. 👏
Lovely rich product, plants are loving it
Again this is great stuff and for the price it cant be beaten!

Brilliant quality

Not actually needed to use this yet but it looks good quality and well packaged
I might be a bit premature with this review as I have yet to see a change in my plants, though through experience I know I will be in good hands. Taking away the guesswork and time it takes to ratio the soil components yourself is worth paying a little extra for. It also makes a wonderful change to see beneficial live organisms in the mix rather than fungus gnats and plastic litter from commercial garden centre bags. I appreciate that the packaging is resealable and includes a guide on which mix will work for each plant. Delivery is super quick and packed securely. Will definitely order again.
Great item, shipped fast. Thank you!
