Garlic friendly cover crops?

Hi Nick I have been building my garlic stock over the last 4 years, I hope to plant around 600 decent size cloves this year.  I live in subtropical Australia, I get no frost and rainfall of about 1400mm per year. This isn't really garlic country, however there are 2 varieties that have been developed to work around here.  We plant late March (Autumn) and harvest at the start of spring (September) here, so it only takes about 5 to 5.5 months to grow here.  I suspect this is a lot different to what is done in more common, colder garlic growing areas (I think I read somewhere it takes about 9 months to grow generally).  Unfortunately weeds also grow fast here.

This is my first year experimenting with living mulch around the garlic, Im hoping it will be successful because it takes me a lot of time to mulch the garden beds by hand.  I am going to try cowpeas and nasturtiums.  Both will thrive and be quite dense

I also hear garlic it's a very good tick barrier I have yet to test this theory for myself but ticks are a problem around here I guess there have been some studies on eating more garlic making bugs like mosquitoes  to leave you alone by like 30% bite reduction or something like that again it was an article I read a long time ago

My favorite living mulch is sweet alyssum because it smells so sweet ...
