If it’s your first go at growing, I’d do nothing but add water. They’re in good shape, so all you gotta do is not mess them up. Like mentioned above, your biggest problem will be overwatering, so be cautious. If they’re in the sun all day, they can probably handle a good watering every other day. But that’s ONLY on days when they actually get a lot of sun and it’s hot. If it’s cloudy, they won’t get as much sun and thus water will evaporate slower so I skip watering on cloudy days. But it’ll take some time for you to get a grasp on how fast water is evaporating from your soil given your weather conditions. I’m also in Virginia, and lately with the heat I’ve been watering every other day and haven’t run into problems.
