I see some great advice here. Honestly, I use "intensive gardening" and companion planting to keep my weeds to a minimum, and watering to a minimum, too. I also do a lot of mulching with compost (or sometimes alfalfa hay depending on the plant) where there are gaps - that way I don't have many weeds. I only have had to week twice since we planted in early March, and my weeding too all of five minutes - probably a dozen little plants. I've done this before with intensive/block planting and had the same results, ironically also in another horrible drought year like we're having this year (worst since the 20's in Texas).
