This compost and topsoil has been great…
This compost and topsoil has been great for topping up my new garden allotment beds. We put in 5 very large beds and managed to get them really full using manure from the local stables and about 30 bags of supagrow to top it all off. On one of the beds I also added 4 bags of topsoil to give the soil more structure. We managed all of this for next to nothing, and it was a great growing season.
Hope you see more bags in stock this year at Wilko!

Just waste not compost
For those who want to complain about this compost, it's no use to email their customer service or sales department. Instead, try the Of&G organic website and look for the PAS certification. There is an email address there for the certification body and maybe they will investigate the issues with this compost.

Have had SupaGrow compost and topsoil…
Have had SupaGrow compost and topsoil quite a number of times. This year's batch of compost is absolutely dreadful. Smells very like leylandi cuttings and is FULL of plastic, stones, sticks, polystyrene and broken glass. Will not be buying this product again. Will be looking for receipts to see if I can return what hasn't been opened. Put some in the garden with flower seeds and nothing has germinated. Shocking and unacceptable quality supposed to be "organic".

Plants died…
All my tomato seedings which were growing well in seed compost died the day after I potted them o n into the potting compost I bought from the range. I then did an experiment. Six seeds into my seed sowing mix potted on 3 into the Range compost mix and 3 into an alternative compost from another compost( it was B &,Q) which normally wouldn't use. The Range ones died within 2 days an the others are thriving. I have now lost all my specialist F1 tomatoes which I cannot replace

Morning Mr Johnson,
Thank you for taking the time to share your experience with us. We are truly sorry to hear about the loss of your tomato seedlings and the disappointment this has caused, particularly with your specialist F1 varieties which, as you mention, are irreplaceable at this stage of the season.
We take all feedback seriously—especially when it concerns potential issues affecting plant health. The outcome you’ve described does not reflect the standard we expect from our potting compost products, and we fully understand your frustration.
We would like to investigate this matter further and would be grateful if you could provide the following:
• The batch printed on the bag
• Any photographs you may have of the compost or affected seedlings
Please email this information to sales@supagrow.co.uk, and a member of our technical team will review the issue as a matter of priority. We would also like to discuss a suitable resolution with you directly.

The worst compost I have ever come…
The worst compost I have ever come across. It killed various seedlings that I potted on using it (cosmos, chilli plants, zinnia, phlox) and killed off all the radish I put in it in a raised bed.
When discarding the seedlings, the smell of the compost with horrific. It was thick and smelt of sewage.
There were also random bits of glass and metal in the compost.
Please avoid this product!!

Thank you for your feedback.
We are genuinely sorry to hear of the issues you've encountered with the Supagrow compost and fully understand your frustration.
A smell is completely normal and will 100% disappear over time.
The presence of foreign matter of glass or metal is certainly not in line with our quality standards, and we take such reports very seriously. Our compost products are subject to screening and quality control procedures, and your experience clearly appears to fall short of what we aim to deliver.
We would appreciate the opportunity to investigate this matter further. If you are able to provide the batch number and, if possible, photographs of the material in question, our technical team will review it thoroughly to ensure appropriate action is taken.

Awful stuff
Awful stuff. From the stench that comes from it for the first few days down to the mixture and the growth if plants. It doesn't hold moisture doesn't feel like compost at all and has killed several plants of mine. Highly disappointed and won't be buying again and do not reccomend anyone else to purchase it just because it's cheap! It's worth spending that bit more.

Truly awful compost
Just as many others have pointed out this really isn't very good soil. Luckily I hadn't actually planted many plants at all yet and therefore may have saved myself a lot of money but I noticed my one plant that normally is super easy and particularly low maintenance most years suddenly looks very lifeless as soon as I had planted it in this soil. I therefore investigated and had come across these reviews, it's obviously not an isolated event. Please do not buy this soil just because it is cheap.

This killed my plants too
Unfortunately like the previous reviewer's experience, this also killed my plants. I recently purchased 4 bags of this compost last weekend and was excited to pot on my plants that I had nurtured from seed. Within days they've dried and died. All my hard work has been undone. I suspect there are sterilising chemicals in this compost to keep it weed free that is also kiling plants, rendering it 'NOT fit for purpose'. The texture of the soil appeared good, I used a sieve and there werent many bits however the colour was much darker than usual compost. I wish I had checked reviews before buying. To the manufacturer: I still have the bags and can provide batch numbers and photographic evidence if it helps.

Zero star rating
Zero star rating. Purchased a bulk order last year. On opening the bags there was an awful smell, a mixture of fire ashes and chemicals. Killed the plants I potted on ( including some expensive ferns ). Horrible texture, no body at all. Vile stuff, I don't know how this stuff is still on sale. Avoid at all costs

I'd say this stuff was a load of poop, but poop is good for plants.
Zero stars. Minus one hundred stars. There is nothing 'Supa' about this stuff, nothing whatsoever. Seriously, this so-called organic compost is nasty, just nasty. My tomato, aubergine, cucumber and pepper plants have been the worst I have ever grown. A terrible yield, lots of blossom end rot, the worst. Did everything right, and I know it's been a horrendous year weather-wise but even so, the results were awful. When will I stop writing this review? When I run out of words that mean bad. Such as dreadful, dire and disastrous (yes, I am using thesaurus.com because otherwise, I'll have to resort to swears). The water just ran straight through and then sat in the tray going anaerobic. It was harrowing, hideous and horrifying. The compost set in the pots like concrete and my poor plants looked tortured, despite all my efforts with seaweed feed etc. Defective, deficient, dissatisfactory. Going in the greenhouse was depressing, infuriating and, as I was growing for a client, embarassing.
Now the company are going to cut and copy in how to get a refund response to this, as they have with the other poor souls who have made the same mistake as me in buying this crud, which says something about the company doesn't it. A refund doesn't replace all the lovely veggies that should have grown. Unsatisfactory, unacceptable, underwhelming. Ok, out of words.

1 start is an understatement.
1 start is an overstatement!.. if I could give 0 I would! Worst soil ever !!! Not one of my plants or vegetables like this soil .. it either
Kills them or just stops them growing, And that’s just the beginning.. apart from the bags being 70% of wood and bark and stones ! I have found LOTS of broken glass .. broken pieces of wire some mesh of some sort, peace’s of sponge.. and peace’s od sharp metal! So if I was anyone buying this soil be careful and don’t let your kids play with it or it will be a trip to the hospital with an infected finger.

Terrible Compost, Kills Plants!
I like many others bought this compost from the Range and regret it. I bought 4x bags of f for £10 but the compost has killed all the plants I used It on.
Around £100 of plants were damaged. I have rescued what I could but am not impressed. Looking at the reviews this also doesn't seem to be an isolated problem as others still seem to have the same problem.
I am surprised to see this is still for sale. I have contacted the Range as well as this issue needs resolving. It’s the only time I have ever had this problem with compost.
