Review: Great product for drainage problems - Great item slowly but surely eats away the clumpy clay under my lawn, it's drained loads better. I drilled holes 2 foot deep put a 1kg in each hole. Mostly filled the hole with water and left it to drain for a few days. I then packed it with compost as that burns at clay too. Topped the compost up a few times until it was firm. Last few inches I put topsoil in. Worked great after a few month. It takes time. I will do 6 monthly sprinkling sparingly to keep at that clay. It did great at the bottom of planters but just a tiny bit. Just don't use on acidic soil loving plants, check guidelines on plants
Review: Easy to apply - 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.

## Features

- Here at Elixir Gardens we supply to many professional growers as well as a range of garden centres, nurseries and landscaping businesses.
- The main purpose of Gypsum is to make the small particles in clay soil join together into larger particles (like that of a sandy soil) which enables better water penetration and retention, as well as better root penetration. In turn, this also enables better nutrient uptake and usage by the plants.
- In a new or established garden if you have a layer of clay or hard subsoil type of soil. This type of soil creates poor drainage, soggy soil and soil compaction.
- Gypsum is also useful for repairing soil that has been damaged through compaction, either from heavy stock, machinery, in the recovery of sub-soils exposed by earth movement or in soils affected by salinity. Because it reduces salt levels in soil, it is effective in coastal and arid regions.
- One of the main uses of gypsum is to remove excess sodium from the soil and add calcium. A soil analysis is helpful in determining if you need to apply gypsum as a soil amendment. Additional benefits are a reduction in crusting, improved water run-off and erosion control, assisting in seedling emergence, more workable soils, and better percolation.
- Slow release formula.
- NOTE: The appearance of this fertiliser can change between batches due to the raw ingredients used in production. Additionally supplied packaging may differ from that displayed.
