I am really pleased with this product ( John Innes no. 3). I had a pallet load which was really well packed and the bags were a sensible size/weight. The compost quality is excellent and I have already used a third to pint on table up hundreds of new bulbs. I shall certainly be back for more.

Peter Chapman from Sheffield on 05/06/2022

I have ordered the John Innes No 3 compost for several years now. In my experience it is an excellent compost. It is easily wettable and moisture retentive but free draining. I have used it in the greenhouse and outside and everything I have grown in it has done well. Some perennials have grown well for several years in the same pot of compost which would be unlikely to happen in a multi-purpose compost. I have also used the spent mushroom compost for several years and that is also excellent. The service from CPA Horticulture has been first class. Every order has been delivered at the time they said.

We get a pallet of this every year for flower, shrub and bulb pots, planting out seedlings, vegetable raised beds, patching up lawns and to add a layer of good soil to existing beds. The results are fantastic because of the nutrients, texture and drainage of this compost. The delivery was second to none in being helpful positioning the pallet where we wanted and getting it down the slope of our drive. Highly recommended!

Quality of the John Innes 3 looks good. Too early to tell whether plants will thrive. There was an issue with the delivery schedule. But the CPAH customer support was good and sorted out the delvery by the following day.

Must say that the delivery was as promised and being sceptical about the quality of the compost ordering via internet, it looks very good. The medium looks about the right mix for John Innes No3. Although I won’t be using for a month or so yet to see how it performs, compared to buying individual bags from diy stores etc it should be a real bargain.

Nice quality product in 20kg sacks. I expect a bulk bag would be more eco friendly but these are convenient for me as 67 year old lady gardener and I take the bags to the soft plastics recycling point. Helpful, friendly, Palletways delivery man who arrived within the given two hour slot. All round, very pleased. Many thanks

Painfully expensive at current price of £125 for 700L, but consistently high quality and an excellent long-lasting mix for raised beds on heavy clay, unlike some of the cheaper topsoil/compost mixes I've used have used.

Ive just received a “loose bag” of John Innes No 3 and a consignment of Ericaceous compost with John Innes. This is the 12th consignment from CPA Horticulture and I’m yet to find a fault in their deliveries or the quality of their products. As always delivered when promised, and predictably the products were excellent.

I’ve had numerous bags of this John Innes blend over the last couple of years and it’s excellent. I have a heavy clay soil in my garden and I have been digging this in my borders to improve drainage. The plants have been growing well and weeding is made considerably easier. There are no stones in the mix and I have also used it in my tubs and hanging baskets and for potting up plants. I will be buying more in the future.

Delivered a day early despite being updated online that it was coming on the Wednesday. No problem as driver could put it at the side of the driveway, and its too big to pinch! Interesting, mix must have been done when wet, as soil was somewhat in round lumps and the mix wasn't homogeneous as you find in bags but reasonable value in bulk. John Innes can vary considerably between suppliers but it appears to be less sandy than some. Probably would order again following assessment of performance
