    Best compost i have used with amazing results over the last year, even better that it is peat free. Also like that the whole process is done locally too.

    Great stuff. Ideal for no dig as it is really rich. Use it for everything except seeds. Great value.

  16. Patrick McCarthy

    I never actually got this product. The guy at te site loaded the car with soil improver before I realised it and I didn’t have the heart to ask him to swap it. I am mixing this with old compost and using it in pots. Looks like a good product and I hope it sustains the Summer plants

  17. Jude Nixon (verified owner)

    Kelpie compost is absolutely brilliant. It gives fantastic results for seedlings and growing both veg and flowers. I will definitely order again

  18. Sam Ferguson (verified owner)

    Looks good quality and is nice to work with. Too early to comment on effect on plants as only used it a few weeks ago.
