In one word : "mulch" !
It impedes weeds sprouting, and development, smothers new weed seedlings
It retains moisture - less watering, fewer trips to the garden
Use whats available (and free) before you buy !
Mulch: rice hulls , buckwheat hulls, leaf litter, pine needles, straw ,
coccoa hulls, rinsed seaweed, pine bark , commercial fabric, cardboard , and newspapers, etc., etc.,...
thanks, I like the free idea too. I’ll start collecting leaves each fall.
