"... if this might actually be good.."

You'd think! But OTOH, there's increased competition for nutrients.
Haven't tried it, I mulch. If you continue, hope you let us know the results.

Alphonso is right.
True that clover is a nitrogen fixer/green manure, but not while growing. Clover is benefitial when tilled into soils, before you plant shallow rooted veggies like garlic.
However, it may be planted between tomatoes, eg, to act as live green mulch.

RATS! I was trying to justify not pulling weeds.
