I dont consider vegetable gardens falling under landscape or lawn watering.
I have actually cut my watering back to 10 minutes in the morning and evening on Wednesdays and Saturdays.
I got away with this due to the sprinkler heads I used the ones you normally see lose 60% of their water in the are.
mine lose from 10 to 20%.
Our water restrictions here allow you to use drip anytime.
I looked on your restrictions and saw that you can water newly installed plants with drip or hand held hose for up to a year.
Any day for 2 hours.
You can find this on page 3 of your water restrictions.
I would consider a tomato plant newly installed.
