It sort of depends on the weather and the sun and wind. I tend to water mine every other day. You just have to watch your plants and decide what they like.

My siding for my very first sfg/victory veggie/herb garden will be arriving next week. I've never really grown vegetables before, just tossed tomato and pepper plants in among my flowers with great success.

I was also a little concerned about watering this new garden, given how hot the summers are here in Texas, how most veggies/herbs are said to require sun, and the new garden's location in exactly that - full scorching sun.

So, to solve this, I decided to make ollas for every few feet of the garden and let the plants water themselves. It should save me time, money and worry *keeping fingers crossed*.

I think it depends on your soil & amendments. My garden is on a section that has fairly shallow black clay on top of white rock. We tilled in a lot of compost and manure before we started a couple of years ago, and have since expanded the garden but haven't added more compost. I have noticed that the area with the most amendments is looser and dries out faster than the expanded area that is mostly black clay.

You can get a water tester with probe at Home Depot or big garden center, and find out when your roots need water.

I'm on the coast so my garden gets salt spray, constant winds, high humidity, the soil is pure sand, water just goes right through....
Depends on what I'm growing, how established it is before the heat hits... so many variables.
I try to make it about every other day to check. If anything is wilted or looks dry I water. Sometimes I don't water for a week or more.
Tally HO!

Should the roots be moist at all times? No. Damp maybe, as in not bone dry, but not wet or moist or you'll get root rot.

Is a good soaking every 3 days best? I've been told everyday, every 4 days...I just don't know. A good soaking is infinitely much better than a light watering. Other than that, timing depends on how hot and how dry it is. You may water once a week in spring, but every day come the hottest part of summer.

So, how to get un-confused? Follow this rule of thumb ~ stick your finger into the soil of the bed all the way up to the last knuckle, all the way up to where your finger meets your palm. If it's bone dry, water. If it's not, don't. It really is as simple as that. Works for potted plants, too.
