I have a big problem with my clay soil.

I have spent the past 5 years trying to improve the soil but to date  still no joy.

Can anyone give me good advise on how to improve my soil.


Unless you have laods of money to pay for man power, grit and organic material to break up the soil and improve its texture, you're going to have to be patient.   You can go round with a large tined fork poking it into the soil as deeply as you can, wiggling it back and ofrth and then pour sharp sand down the holes to improve drainage and aeration.    Annual mulching in autumnw ith a few inches of well rotted garden comost and/or manure will also help.  The worms will work it in over winter and, in time, you'll end up with lovely soil.

There's another thread about clay soil and teratment advice here -



You really need lots and lots of compost, manure, grit and sharp sand.

How is your soil used? A book i have recommends growing things in it to break it up. I know that can be easier said than done with clay soil, but having dug in plenty of organic material last autumn I'll be filling in all the gaps in my border with annuals this year. On the plus side clay soil is supposed to be very fertile, and there are some plants that like it.

We're also cheating and putting in a raised bed for veggies.



Hi, I have read that clay soil is actually the most nutrient rich but you need to add sharp sand, gypsum and mulch to break it down. Does anyone have the correct ratio of these? Also, how much would  need of each for a garden of 90 square metres? 


I have heavy clay soil so use loads of horse manure and leaf mulch and do it every year. Hard work, but it helps


I do not think there is a correct ratio as such as it depends on the plant you want to grow.

Soil (compost) for nutrients and minerals.

Silt opens up the clay/soil to allow drainage and aeration and also provides vital nitrogen. 
clay holds the moisture in the mix. Climate and crop type play a huge part in determining the ideal ratio , but the theoretical formula of 3 parts soil , 2 parts silt and 1 parts clay 3:2:1 may not be the answer you need as this is based on outdoor wheat/maize production at least you have the reasoning which i hope helps. 
also if you search for " sandy loam " on your computer i'm sure you will get all the info you need. 
sandy loam is the agricultural term for the ideal soil ratio.
