Plants that are good at breaking up clay include those with deep tap roots, like daikon radishes, and those with fibrous root systems like rye or clover.
Add Compost
If you don't want to wait a year for plants to grow and die, add compost. Compost is organic matter already broken down by bacteria and worms (through " vermicomposting "), making their nutrients ready for root uptake. Compost or composted cow manure (which has little scent) is commercially available and garden centers.
