British Gypsum for Agricultural Amendment, Amend Very Compact Clay Soils, 25 kg Bag

Our garden is heavy clay soil - we have tried everything to stop it bogging in the winter but we always fail miserably, which requires the grass to either be re turfed or re seeded every single spring - this has gone on for 12 years! Our garden becomes to muddy that we are just unable to use it over the winter months. We have had some very heavy rain recently and since putting half a bag of this gypsum down the grass has stayed green and alive and the clay has not bogged - no water pools! So far i am super pleased - lets see how we fair over the coming winter months! However first impressions are great!

All good fast delivery despite the bigh weight, perfect for the job.

Our garden was quite boggy, you couldn't walk on it for sinking and sliding about, I added loads of rotted manure and 3 tons of sharp sand, left it for about a yr now I'm trying the gypsum. I put the gypsum on our clay soil a few days ago, I think its working, im quite impatient in getting the garden sorted but it all takes time! In some parts its still quite sticky and heavy so will need to buy some more gypsum. We don't sink or slide about and in some parts its quite crumbly so yeh getting there! Its good that it doesn't alter the ph of the soil when you just need something to break the clay up and aid drainage plus it adds some nutrients for plant roots too when eventually we get to be able to plant some plants! 😊

This is a simple product for a simple job: break up heavy clay without changing the pH. It does the job well, taking minutes to apply. Three months later, my heavy clay looks like a crappy soil instead of one homogeneous clod of damp. I'll mix some manure in next to give it texture and then it'll really help with drainage.

We used this agricultural gypsum on the very wet area of our clay soil garden. It is very fine and covers the garden with white powder - it works! Within a week there was a massive difference in the lawn and borders, much drier and able to be worked even though we had more rain. We feel this is an excellent product.

I am amazed at what this product can do for clay soils. The real treat has been the welcome return of so many birds and especially the two nesting pairs, that regularly feast on the huge fat worms that worked their way up, since the soil is now so lovely and open. I managed to hack back some lawn last year and so I'm dealing with a patch that's now about 10 ft x 4ft. I cannot believe how quickly this substance gets to work making the clay particles clump up. I bought this large bag (that's certainly heavy to move) for the second dressing on the flower bed, then the front and lastly the lawn. I would imagine the lawn might be a tad muddier during wet spells, after using this? but I've also got a feeling it will thereby reduce the moss build up I have to control every Spring? We'll have to wait and see, but I wish I'd used it years ago.

Even after a month of being dug in I am not sure it’s broken down the clay at all.

Only time will tell if this is effective on my soil, but I am hopeful. There is a lot here, which is what I wanted, knowing that I will have to treat my clay soil multiple times this is very good value. As a side note, it was delivered much quicker than the estimated time. A+
