My greens keep for over a week with no wilting and I wash them before I store them.
I open the bunches of parsley and cilantro, and separate the leaves of romaine. Throw out any stuff that doesn’t look good. Wash each type of veggie separately. Then I store them in a way that I found out about on this site. I have three rectangular stackable plastic tupperware containers with holes poked through one side for ventilation. I put one paper towel flat on the bottom, then a layer of veggies, then another paper towel, and another layer of veggies etc. until I’m done. One type of veggie per container.
I only really shake out the veggies before layering them in the container. I don’t let them dry completely or anything, and they’re still pretty wet when they go in.
Makes it so much easier to just pull out veggies from each container to feed Sammy. I’d rather do all the hard work on the day I buy the veggies, and then be able to do things much more quickly in the morning/evening for the following week.
