Elixir Gardens Gypsum | Calcium Sulphate Clay Breaker Agricultural Grade Natural Soil Improver | Homogenous Granule Wind Resistant | Various Sizes 250g-25kg | (1kg) | Treats 5sqm

This product is recommended by a lawn professional in their online videos, so I'm confident it'll make a difference on my garden, where there's some pretty thick clay.The granulated formula means it'll be easy to spread consistently using a hand spreader, and it should help my flower beds as well as the lawns.The price seems pretty reasonable for the weight. This seller also has some keenly priced fertiliser, so I may give that a go, too.

I bought this, as I have a really heavy clay soil. The main thing I was hoping to do was improve the drainage under my lawn by braking up the clay.This product comes with straightforward instructions and doesn’t take long to apply.I used this over a month ago and so feel I can now review the results.This has made a slight difference to my lawn, although not the level of impact I had hoped. I applied it after removing plugs from the lawn to try and get the product deeper into the lawn.You may then wonder why the 4 stars....I also used this on some of my planters, which have a base of clay soil, but I top up with compost. I applied this product and then worked the soils with a shovel and fork, turning it over and the results have been amazing.The soil has changed from a compacted clay to a crumbly workable soil in a matter of a could of weeks.Clearly this product does work, I’m just not convinced it will sort out a lawn in one treatment, but if you have an opportunity to work the soil after application it can have great results as I’ve seen.I’ll be applying this to my borders and planters again next year and will give the lawns a go again too.

Too early to review really as it will take time to take effect as gypsum has low solubility in water. If I can, I will update later.

Needed to break down the soil in the garden as very thick clay I spread this around in the areas needed and worked very well

Hard to tell if this will actually help a clay garden with poor drainage or not. It will take many months or even years of applying gypsum to have a significant effect. But i can say this is granular so easy to spread and has had no negative effects on the lawn. It doesn’t mark paving slabs either.

Iam happy

Always excellent

High quality and easy to spread. Used on lawn as we have so much clay. Hoping it will make a difference. May have to use a few more times to appreciate its full effect. Laid under compost with seeds to cover patches in grass.
