"Pro-Grow soil conditioner was purchased as part of a project working with a school about reduce reuse recycle. The children made plant pots from plastic pop bottles and used compost and soil conditioner in their pots. They learned the importance of recycling and how we use people's garden waste to produce soil conditioner and peat free compost and by doing this we are helping the environment and helping Veolia on their journey to Ecological Transformation"

"Always great as usual to pick up bags of lovely fresh progrow - used this time for mulching a newly planted bed, weed suppressant, moisture preserver and nutrition all in one. Fantastic stuff, wish I had room to buy a cubic litre!"

"I live using pro-grow as a mulch in autumn to provide cover for the soil knowing that long term the worms will be working in this lovely fibrous compost increasing nutrients and water retention for the soil. It is a wonderful cycle, adding program and then when clearing foliage or spent plants they go back in the green bag and become compost again. Fantastic. "

"I purchase two 1m3 bags of pro-grow last year and was impressed by the delivery, no problems. The product was used evenly throughout my garden, vegetable garden and flower beds. When dug in with existing soil it forms a good base for flowers/shrubs and vegetables. Additional benefit in the veg patch, very few weeds. Would highly recommend the product."

"Recently we had a delivery of 200 bags of Pro-Grow to my allotment in North London. It was a great morning work out moving the bags down the pathway to the allotment and a chance to work on my muscle! Everyone seems very pleased with the product since using it the last 2 years, and we have had some great vegetables as a result :)"

"It's my second allotment that I took on at the beginning of this year. It’s on a site in Hook which suffers from Heavy clay soil. Because of the soil I’ve used raised beds on the old plot, and a lot of these were filled with Pro grow. I find the fruit and vegetables love it, and it really retains moisture which is much better than the compost I’ve had in other beds. Compost I’ve used becomes very dry very quickly, and if you have a year like this year with not a lot of rain I find seeds don’t germinate as well as bed filled with Pro grow."

"We have recently moved into a new house and are turning a very bare plot into a garden. Soil improver is badly needed. We are delighted to have found Pro-Grow. We are currently using our second bulk bag. It is an easy-to-use product and makes a big difference to the quality of the soil. Pro-Grow in bulk bugs is good value. It is simple to place an order by phone or on the website, and the delivery arrives quickly. It is good to know that we are using compost from Hampshire garden waste on our new garden."

"When I got your leaflet I ordered 30 bags to see how it was. It's great but didn't go as far as I thought so I've ordered more to finish the rear garden beds, 100 bags for me and 40 for my neighbor as he was impressed with the quality and the price. Great product. Love it. "

"Having used Pro-grow last year, I found the best results worked with vegetables. The key is getting the right balance of mixture (3 to 1). If mixing with a very high quality multi-purpose compost, then only add as directed. If mixing with a low quality (cheap) compost, then used heaped portions (or an extra spade/trowel portion). You can't really go wrong - we had some great green beans, lettuce and radishes that just went on forever! As I grew these in pots, I even used the spent soil as mulch afterwards - so absolutely no wastage. "

"I use Pro Grow as a mulch to cover the soil in beds & borders. A nice thick layer not only helps retain moisture at this time of year, but also on our light chalky soils it gives a lovely dark appearance and looks great!"

"I was lucky enough to receive some Pro-Grow after visiting the Pitsea Landfill open day last year which was good timing as I had just started to dig out a new garden bed. We mixed one part Pro-Grow with two parts compost and planted the bed with Roses, Lavender, Jasmine and Hebe's. They have grown at such a rate and look amazing better than anything I have every grown before just need to put some more in the rest of the garden now."
