Compost, compost and more compost. In the wettest part of my garden I now have a natural clay pond but in other areas I dump all my homemade compost on it and lots of wood chip as a mulch which I get from a local tree surgeon. I have never dug any of it in, just left it for the worms to sort out. Within a year my soil was nice in the top 15cm and now having been doing this for 6 years I have to go down at least 60cm to find solid clay. You will need to do this or at least top it up each year. The other thing to do is when planting in it, dig a hole at least twice as wide as needed and replace the clay dug out with compost and homemade compost and grit. The plants roots are then more likely to spread out rather than go round and round.
