You can buy a beginner set which provides some practice at setting a system up.
https://www.dripworks.com/ Rainbird. Home Depot online might have what you need. (Do they have any stores in Georgia? :)
I think a lot depends on how you have your garden laid out. If you have a lot of 40 foot straight rows with one type of plant (Say corn) you could just go with go with Augie’s suggestion and run a one feeder line at one end of the rows, and put an outlet with a shut off for your drip hoses and that would probably work well. One set up at the beginning of the year with not much change. (Be aware that too long a run and you lose water pressure at the end!)
If you have a number of small beds you might need to use something a little different. I have a number of 2’ by 12’ beds. and several 2’ by 6’ beds. I use a 1/2’ feed and run 3 1/4” drip lines in each bed ) I can get enough pressure to water 2 beds at a time. Then I have to switch to the next 2 beds. It does resolve the issue of mold pretty well. (Use 6” spacing drip lines) I can get a bed planted with marigold in the front sun side, then your tomatoes, and basil at the back and they stay pretty well watered. Read up on it beforehand and start small the first year.
Thank you all for the ideas and suggestions! It helps a great deal to know where to start/look
My garden is long and narrow, I’m guessing I will need to eventually set up zones. We normally have three zones with sprinklers (or we would lose pressure). Starting small is a good idea. I may start with just the tomatoes this year. We may need to have some topsoil brought in, so much of mine has washed away.
