After I wash the veggies, I use a salad spinner to take some of the wetness off of them, then lay them on a paper towel to air dry for a few minutes before wrapping them in the paper towel and putting them in a produce bag inside the crisper drawers. Sometimes my veggies will still be fresh after a week, but sometimes they do go bad in 3 or 4 days. Cilantro is not one of the better keepers, and neither are the dandelion greens that I get that are shipped in from across the country. Some veggies are fresher than others when you get them, which makes them last longer, but it helps to not have them too wet when they are put in the refrigerator and to go through the bunches each day, pulling out any that are starting to go bad. I try to grow parsley, cilantro, kale, Italian dandelions and carrot tops for my bunnies, which can be picked daily and will always be fresh, but the squirrels dig up or eat most of it, so I have to go out and buy it anyway.
