The Cottage Smallholder

I planted a lot of garlic this afternoon. I'd bought the bulbs at The Garlic Farm stand at Hampton Court Flower Show. I put in a row beside the recently sown carrots and then I decided to fill up the gaps between the cabbages with garlic. I've heard of companion planting and nipped to the laptop to see whether cabbages would like to nestle beside garlic. Apparently they do and the flavour of the cabbages improves.

Then my eye fell on planting foes - garlic hates beans and peas. The row beside the carrots is next to some early peas. So the garlic is coming out tomorrow! Now I'm begining to wonder whether peas like carrots..

Has anyone any experience of companion planting? What works and what doesn't etc.
